Re: Should we stop analyzing?
Hi Nuno, > > Do they clone the production database, change the statistics, prove that the > > system can complete it's batch job in 8 hours, then install ? I doubt it. > > Exactly my point above. Not feasible. So, what's the alternative? You hit the Nail on the head here, Nuno. The central questions about stats changes are: 1- How can I list the changes to execution plans after re-analysis, A Priori? 2 - How do I justify the risk (and server expense) of re-analyzing? Some alternatives might be: 1 - Enhance the dbms_stats "auto" option (monitoring) to make it more intelligent. Wouldn't it be nice if dbms_stats could do an "incremental" refresh, tracking ONLY stats changes that might make a difference to execution plan: a) Changes to clustering_factor b) Changes to column skew. Only create histograms when column is skewed AND SQL uses the column. The 10g workload tool "claims" to do some of this. c) Changes to highest-lowest values of key indexes, etc. 2- Devise a method where new stats can be collected, stored and compared against historical SQL (from stats$sql_summary) a) Allow for dbms_stats to collect, store and compare changes to historical execution plans, using historical SQL from STATSPACK (or new 10g workload views) b) Allow the DBA control about whether to implement the new statistics > itwouldhavehelpediftheyhadfixedthecodebackin7/8/9insteadofdelivering > aseriesofpatchesasnewreleasesthattotallyconfusedeverybodyaboutitsoperation Yes! IME, there ARE still problems in the CBO, especially with complex subqueries. I have more than a dozen systems where management insists on staying with the RBO! Every time we collect deep stats and histogram and switch optimizer_mode, hundreds of statements generate poor plans. It would cost these clients many thousands of dollars to have adjusted these plans, and management says "If it ain't broke, why fix it". We need look no further than Oracle Applications to see this issue. Oracle made a big-deal about going to the CBO in 11i, yet when we look at the SQL, a significant number of statement employ the "rule" hint! Connect-the-dots and you can guess why the RBO IS NOT being removed from Oracle10g. . . . JMHO. . . . Regards, Donald K.

Re: Should we stop analyzing?
Jonathan, Good point about the "change-control" issue. When we consider that re-analyzing stats can cause huge changes to data access patterns Im continuously amazed at the number of shops that re-analyze on a schedule and have the Monday Morning syndrome. I have worked for shops where they must certify every change, no matter how trivial. Mostly banks and medical systems. These certified shops are stuck. On one hand, they are obligated to follow the best-practices of their vendor, yet obligated not to make any untested changes in production. Even Oracle is schizophrenic on the issue; my contacts in the real-world performance group are zealously in favor of the take one deep sample approach, while the 10g developers are pissed that the CBO has been getting a bum-rap because of crappy statistics. Personally, I love the automatic histogram generation skewonly and the auto option in dbms_stats, and use it for all my 9ir2 clients. However, I remain skeptical about the benefits of dynamic sampling and workload analysis automation tools for most shops. In my experience, the vast majority of shops DO NOT benefit from re-analysis, and Ive got shops where re-analysis NEVER results in CBO changes. Regards, Donald K.

Client-server Forms6i against Oracle 9i (9.2.0.4) database?
Is it possible to run Forms6i in client-server mode against an Oracle 9.2.0.4 database? One of the developers where I work flatly states that Forms 6i (in any mode) doesn't work against (any) Oracle 9i and I cannot find any specific information either confirming or denying this assertion. Searches on Metalink and Google both came up with nothing of relevance. I would assume that with an Oracle8i client it shouldn't be a problem, but I haven't worked with Forms at all since v3.0 and she is adamant that it is simply impossible - with no explanation of why.

Re: urgent Help!! FYI
Freeman, Before I change it, listener.ora property is like the following: $ls -al listener.ora -rw-rw-r-- 1 oracle oinstall 1732613 Jul 18 16:02 listener.log After I change it by the following steps, it works fine. $chmod 666 listener.ora lsnrctl start Now Oracle listener starts up.

Re: urgent Help!! FYI
Dick, It works now after I change the $ORACLE_HOME/network/log/listener.ora to like following: $ls -al listener.log -rw-rw-rw- 1 oracle oinstall 1732613 Jul 18 16:02 listener.log But before the parameter is like following: $ls -al listener.log -rw-rw-r-- 1 oracle oinstall 1732613 Jul 18 16:02 listener.log I just don't know is this file property changed or not? If changed, who changed it. But before power off, it works fine. Thank you very much again! Don "Goulet, Dick" wrote: > In your listener.ora file add the line "logging_listener=off".

Re: How to make SPFILE in sync with INIT.ORA ?
Hi, I really need some helps to configure my database with audit_trail option. I have tried some but fail so far. My database is Oracle 9.2. I have read all email related to spfile. Can somebody provides simple steps for me to update my specified initialization parameter in init.ora? (1) Manually change the initialization parameter, e.g. audit_trail = db in init.ora. How to sync it when re-start Oracle database? (2) Can I change the audit_trail = db initialization parameters in init.ora on-line? Any comments are appreciated! Many thanks!

Re: security without using different usernames
Pete,
I follow your steps to enable audit_trail = db in init.ora located in
ORACLE_HOME/dbs
and restart my Oracle database on solaris. After my database is up, I do the exact
query in your paper and results as followings:
SQL> select name,value from v$parameter
2 where name like 'audit%';
NAME
VALUE
audit_sys_operations
FALSE
audit_file_dest
?/rdbms/audit
audit_trail
NONE
Please tell me what is possible causes that I fail to enable audit on my database.
Any comments are appreciated!
Many thanks!

Re: Oracle security question
Ron, I have urgent question. Because I want to shutdown my database, I login as oracle and execute dbshut. But later I found that the process is very slow so I realize that I should type shutdown immediate. Then, I use control-D to stop shutdown command. And I re-execute "shutdown immediate". Now the shutdown command seems to take longer time to finish. Is there something wrong or normal? Any comments are appreciated! Thanks!

Re: Oracle security question
Dear Guang Mei: Thanks for your message. Your suggestion is very helpful. After reviewing all possible uesers, I have locked them. Now I have only one concern that if nobody knows my database's sys and system's password, there should be no way to unlock these accounts. Am I complete right? Thanks! Any comments are appreciated!

Re: Oracle security question
Dennis Thank you very much. My data in that database is changed three times. The first is whole data being delete. The second is over ten thousands records being added. The third is whole data related to a month being deleted. I know my working environment is very complicated. For this report application, I write shell scripts and C/C++ program to parsing Apache web server access log file (www.welch.jhu.edu) in order to get client ip, access date, and host ip, which are associated with the special pattern as "ntlinktrack.cgi", which is associated with Library E-Book,E-Journal, and E-database. Then I need to schedule a solaris cron job to process access log daily and load parsed data into database. Also I create some log files for saving intermediate information from my program. Then I create some ColdFusion pages to post these results into website. In my database there are over million records. Oracle DBA is new duty for me since I had found that my data was missing. This is the reason I post my question on Oracle user group. Now I am trying to read as much as I can but I do not have much time. I want to make sure my database is secure as early as I can. So what do you think of my reason? Thank you very much! Don DENNIS WILLIAMS wrote: > Don > SYS is the owner of the Oracle dictionary tables.

Re: Oracle security question
Dennis: Thanks for your message. Now I have changed sys password by the following command: alter user sys identified by xxx But when I try to login from sql plus window by using sys, I cannot successfully login. Also I get an error message. The message is something like "connection to sys should be as sysdba or sysoper". So my question is what sys for? Thank you very much!

Re: Oracle security question
Stephane, Thanks for your message. The reason I ask this question is that now I am responsible for creating some reports based upon this database. But I have found that there are unaccountable data in my database, which is not from my insert script or my cron job program. Thanks!

Re: index on null column
Queries against the non-null values should benefit
greatly. Queries on the null values will not use the index since null
values are not indexed (at least in single column indexes). It is an old
trick to create an index on something like STATUS where the vast majority of
records have a NULL (meaning perhaps "PROCESSED") and a small percentage
of the records have other non-null values for STATUS ("PENDING","APPROVED",
etc.).

Re: Oracle Performance Tuning Exam
Sorry for the very late response, but I've seen a lot of similar postings recently. I've been lurking for some months now, when I have time for even that, but I've never been accused of being under-opinionated, so... In my opinion, the exam to take first is the Architecture & Administration exam. Anyone with any sort of significant Oracle DBA experience should be able to pass it cold. If it doesn't seem too easy or doesn't score well, adjust the exam schedule and allocated study time accordingly. I took the 8i Architecture/Administration exam and the 8i Backup & Recovery exams on the same Tuesday at OracleWorld 2002 with zero preparation other than experience. I finished the first in under 20 minutes, the latter in about 35. Both seemed easy. Of course, there were some "trick" questions, some RMAN syntax trivia, and other OCP exam inanity. Two days later, I took the SQL & PL/SQL exam. I "crammed" on obscure syntax and advanced stuff for about two hours in the IOUG bookstore in the exhibit hall immediately prior. It was unnecessary - no advanced stuff appeared on the exam (Warning! Your mileage may vary.). It was easier than I thought based on what I had heard about it. It wasn't really difficult, but it was a little tricky in places and a bit tedious in places. All the other exams were allowed 90 minutes, but this one was allowed 120 minutes. I actually took about 65 minutes (almost twice as long as any of the other five for 8i + 9i) due to checking over every answer twice and some of the "tricky" questions thrice. I think that the vast majority of experienced DBAs could easily pass these with an 80%+ score with no formal preparation. The only caveat is that one needs to be conversant in RMAN - the basics at least. The tuning exam was "a bit odd". Knowing that it required the "party line" answers, I spent about two hours reviewing the various ratio formulae and memorizing other fairly useless trivia. Some of the questions had no truly correct answer - especially some that said something like "pick three..." when there were definitely NOT three "correct" answers (and perhaps not even two - or one). This one might require some study by even the most experienced DBAs. Actually, the amount of "prep time" required might be directly proportional to one's tuning expertise! The fairly naive might actually score better than actual experts given the same prep time! There were a number of questions that should have had a "none of the above - no matter what the book says" choice - or perhaps an optional write-in answer (e.g. "I refuse to answer - even the question is utterly irrelevant and misleading!"). I studied about 12 hours for the networking exam - primarily because I've never used connection manager, Oracle Names, or OID in "real life" - and have only rarely used some other stuff like MTS. This exam was *much* easier than I anticipated. However, it did have a few "GUI trivia" questions - stuff like knowing what menu something is on in netca, picking among four very similar possible answers for the exact wording on some boilerplate or menu, ad nauseum. (Kind of missed the point of GUIs didn't they?) I took the 9i upgrade a week later, but studied for it most of the week (The week of Thanksgiving - 4 evenings, one Saturday and a couple of hours per day for the three days at work). It could be considered the most difficult since it covers only 9i new features - few of which one might have any "real life" experience with. It covered most topics at the conceptual level or a very basic level, but there were a couple of extremely esoteric technical questions that almost nobody would even attempt to answer in "real life" without consulting a manual. All these OCP exams were far easier than I ever thought they would be - even after taking a few. Most of the questions were of a conceptual or rather basic nature. All the exams had some serious flaws - questions that were ambiguous, the wrong "correct" answers, obscure syntax trivia, GUI trivia, too many questions about things that (almost) nobody ever uses (e.g. OEM's Oracle Trace), etc. A significant part of the game is in knowing how to take exams. In this, I've had a lot of experience - about 240 university semester hours and three degrees. If you don't see an obviously "correct" answer right away, weed out the obviously "incorrect" answers. Never leave a "multiple guess" question unanswered if there is no penalty for missed guesses. Et cetera... After having gone from 0% OCP to 200% OCP (8i + 9i) in about three weeks in November, perhaps now I can say "OCP doesn't mean squat - except to HR checklists" - without appearing to be just another crusty old curmudgeon

Re: SqlNet Response ports
I guess I should have asked also:
1) what version of Oracle are you using?
2) Is this using MTS or dedicated servers?
Since this is Linux, there are three cases:
1) Dedicated severs - there is no redirection. Client talks to dedicated
server on listener port.
2) MTS & Oracle 9i - ditto
3) MTS & pre-9iR2 - MTS does redirect by default 0 to some (pseudo-)random
port above 1024 but this may be overridden by adding a pfile (init.ora)
entry like:
mts_dispatchers="(address=(protocol=tcp)(host=yourhostname)(port=443))(dispa
tchers=1)"
See: Metalink Bulletin: 1016349.102 & Note: 163082.999
Go to advanced search and search on "Doc ID" with these IDs.
There may be multiple mts_dispatchers= lines in the init file and there may
be other parameters of interest. For the sake of this particular issue
though, the pertinent item is the ("port=443)" clause. It would force MTS
redirects to port 443.
Actually, this parameter is obsoleted by the initiiation parameter:
local_listener=listener_name_alias
where tnsnames.ora has an entry like:
listener_name_alias=(address=(protocol= tcp)(host= yourhostname)(port=
443))...
and other appriopriate MTs initialization parameters.
Please see the documentation for your version for options.
Good luck!

Re: Oracle Tech Support
description of the differences (few except for time), and still got the idiot treatment. I said it was a bug and nobody would even consider the possibility. For about twelve rounds, they kept saying stuff like that I couldn't expect the query to run the same unless the hardware was identical (even after I explained that 8.1.7.4 was running on a single 1.2 GHz PIII CPU Dell desktop with Linux 7.2 and 256M RAM and a single IDE drive, but 9.2.0.2 was running on a dual 1.4 GHz Dell server with Linux 7.2, 4G RAM and the 9i database was alone on a Dell/EMC FC4700 array with 2 GB of cache and a bunch of 15k SCSI drives set up with RAID 0+1 (except for redo on dedicated mirrored drives) Or that I should consider moving redo logs off of disks with other datafiles.. Or that the datafiles might need to be redistributed to balance I/O (How much I/O does "select name from v$datafile" require? Is I/O redistributi9on likely to make it 400-600 times faster? Besides, the database and system was idle except for me and a few background processes.) Agh! Guess what? It was a bug. When I later found and applied patch #2773907, the problem disappeared entirely - the query went from >6.5 sec to 0.01-0.02 sec. All the nonsense that support suggested or asked for was entirely useless in solving the problem - and I politely told them so at the time (but humored them anyway).

Re: Preventing select on table
I disagree that it is inherently bad to EVER use a natural key. In most cases, such as this one, it doesn't work very well. However, there are many cases where implementing the primary key as a surrogate key, simply to satisfy a blanket "thou shalt not use natural keys" is overkill and unnecessarily complicates things. As a simple example, consider a table of US state codes to be used in addresses (STATE_CODE, STATE_NAME, ...). Is adding a sequence-generated STATE_ID really necessary? It is unlikely that CA will ever mean anything other than California or that California will demand that it be changed to CF. All that adding a surrogate key here does is complicate the application. The vast majority of users will never need to drill down to see what CA means, but to display anything useful on a screen or report, the surrogate key will always require a join.

Re: RAC on linux
Oracle 9.2.0.2 RAC on RedHat 7.2 is "OK", but 7.2 has no support for CFS or
AIO (As I remember - it has been a while. I switched to AS 2.1, still on
raw devices, months ago.). It was in many respects the least problematic
combination, but is, of course, not officially supported.
As far as the docs go, some are very good (RAC Concepts), some are
marginally useful (e.g. RAC Setup and Configuration). Note that the CFS
docs repeatedly mention "watchdog", even though it was discarded in
9.2.0.2 - months before CFS was even available. Other such contradictions
abound... For example, no two docs seem to call the quorum disk the same
thing - some call it that, some say the "cm" disk, some say other things.
To keep things interesting, they sometimes rotate this usage between docs
when a new version comes out. All quite confusing until you adapt by
skimming over the details.
Don't even think about anything prior to 9.2.0.2 on any version of Linux -
unless you actually want to do *A LOT* of jumping through flaming hoops -
tweaking everything in sight, "faking the watchdog" (really - MetaLink even
has detailed directions for "faking it"), diagnosing random node reboots, ad
nauseum. My experience over the last year with RAC on Linux has been
"entertaining", to say the least.
In 9.0.1.1, the Oracle-supplied cluster management software consisted of
oracm (cluster monitor), oranm (network monitor), and watchdogd (daemon to
randomly crash nodes ;-). Nodes spontaneously rebooted for no apparent
reason - and took all the other nodes in the cluster down with them. This
usually occurred at least a few times per week. ("It will be fixed in the
next release".)
In 9.2.0.1 (I think - it might have been 9.0.x), they eliminated oranm. It
was slightly more stable - only spontaneously, randomly, and for no apparent
reason rebooting one node at a time (usually). ("It will be fixed in the
next patchset.")
In 9.2.0.2, they eliminated watchdogd and added a kernel module named
"hangcheck-timer". It became *much* more stable. I figure with the next
release perhaps they will eliminate the last of the Oracle cluster
management software troublemakers - oracm - and RAC will actually become as
stable as it was initially hyped to be in 9.0.1 ;-)
All this was on a complete front-to-back Oracle "certified" configuration
from a major vendor. [In hindsight, I should have been more suspicious when
they used the "c" word so often and so loudly...]

Re: IOUG 2003
I renewed my membership for 3 years at OracleWorld, so got a significant discount from the $125/year. I mentioned the registration discount for the IOUG-A live! conference registration and they said that was changing too. The person I talked to said that in the future, IOUG membership would be "automatic with conference registration". I'm not quite sure what that means if one is already in IOUG, but I suspect that it means there is no discount!

Re: Partition Question
It depends on your reason for partitioning -- if you mean to drop a partition in the future (to roll off the 1999 data or whatever) then the ID range is potentially a valid approach, as long as ID is serial. If you just want to put chunks on different disk volumes, you could use the type or even a hash partitioning scheme. It's down to what you're trying to accomplish, and what is good for one partition key is probably bad or neutral for the other.

Re: Database design, replacing null by a default value
Properly formulated, a DW only reports on what happened, and ignores what did not happen. If it's really like a DW then you just leave the nulls out. You should do this if you can. Otherwise you have to decide how to lie based on least harm to aggregates. If you average or sum you should use 0 to avoid messing up the sums. If you can use a conditional code to skip a negative, and the negative is not allowed, -1 makes a good null, but you wouldn't want to sum it into an account or anything. Blanks may be an option depending on how Seibel interperets them, but it's probably a coding error. For a varchar I'd use a zero-length string or a single blank, if zero-length isn't allowed. If blanks are significant, first shoot your source system designer, then use ''. :) paquette stephane wrote: > Hi, > > We're in the process of writing functionnal specs for > a system which is like a DW but instead of a DW the > staging area push the data in Siebel. > > If we replaced null by something else. > What would you choose : >for a varchar field ? >for a numeric field ? > > Someone has proposed blanks for the character field > but I'm not comfortable with that. > > TIA > > = > Stéphane Paquette > DBA Oracle et DB2, consultant entrepôt de données > Oracle and DB2 DBA, datawarehouse consultant > [EMAIL PROTECTED] > > __ > Lèche-vitrine ou lèche-écran ? > magasinage.yahoo.ca > -- > Please see the official ORACLE-L FAQ: http://www.orafaq.com > -- > Author: =?iso-8859-1?q?paquette=20stephane?= > INET: [EMAIL PROTECTED] > > Fat City Network Services-- 858-538-5051 http://www.fatcity.com > San Diego, California-- Mailing list and web hosting services > - > To REMOVE yourself from this mailing list, send an E-Mail message > to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in > the message BODY, include a line containing: UNSUB ORACLE-L > (or the name of mailing list you want to be removed from).

rebuilding an instance from a cpio file?
I have a huge cpio file that a sys admin created when it was decided to remove an instance (8i) from a test server. I don't know for certain what to do with this file, but I'd like to get that instance back up and running long enough to do an export of the db. Can somebody help with the syntax to list out the contents of the cpio file? I have read the man pages, but I can't figure out the syntax to just list the cpio contents.

Re: using obfuscation
Sorry, I munged the create view with the query.. I was reminded of a meeting
while typing the note :)
create view my_data as select de_encrypt(sensitive_data) as
clear_sensitive_data, sensitive_data from my_table;
create index on my_table(sensitive data);
select clear_sensitive_data from my_data where
sensitive_data = encrypt('CLEAR TEXT')
Upon review, it does provide a cyphertext/cleartext attack, doesn't it? Just
goes to show you -- security is hard.

Re: using obfuscation
What about...
create view my_data as select de_encrypt(sensitive_data) as
clear_sensitive_data where
sensitive_data = encrypt('CLEAR TEXT') ?
This lets you create an index on the sensitive data without decrypting it, and
the function need only be called once on the clear text.
Caveat: no idea if this should work :)

Re: Velpuri bkup script-syntax error

Re: Oracle 9.2 Stability Feedback Requested
All the bugs? Possible? Perhaps... Reality? Nope. The crippling bugs with SMU appear (at first glance) to be fixed in 9.2, but there is no shortage of other bugs.

Re: Senware AutoDBA
That was truly a disaster of a session. I, and the small group I was with, left almost immediately. I was on the sundeck for the post-mortem though and even have a nice picture of Gaja discussing (emphasis on "cuss") it with Stan. I believe the presenter was the CTO, but I'm not sure. I have been hounded constantly about AutoDBA by a sales rep from Insession Technology. After a cold call from her, long before the conference, I asked for some technical material on it and got only marketing material - even the supposed "technical white papers" were pure marketing blather. I did try to get a "trial download" off their web site. I "registered" only to find out that there was no trial download. Instead, I got another call from the same sales rep offering to come out and give a presentation to executive management - and perhaps, after that, to come out and install a trial version. I have never seen AutoDBA nor used it, but I have formed a strong subjective opinion that it is most likely pure garbage. I apologize if anyone here is associated with this product and offended. Please don't take it personally - my admittedly highly subjective opinion is based largely on the tactics of marketing weasels. Here is the basis: 1) The presentation at IOUG-A Live! 2002 (The last straw - I already had a dislike for AutoDBA before that.) 2) The fact that they couldn't or wouldn't offer any substantial information about it - only marketing rhetoric. 3) The marketing is hyperbole full of exotic-sounding buzz-phrases meant to impress PHBs (e.g. "Utilizes advanced artificial intelligence, predictive analysis algorithms, and intelligent neural network technologies") - and it seems to be based mostly on the standard tuning myths (e.g. "As space is allocated in an Oracle database, the tablespaces become increasingly fragmented which hinders database performance. AutoDBA automatically repairs these fragmented tablespaces, improving database efficiency"). 4) The tactic of wanting to "sell" it to upper management before offering a trial copy or even significant technical information about how it works and what it does. 5) The proverbial "Big One" - I now work closely with someone who was not long ago a manager at a company that markets AutoDBA and was the project manager on that company's initial "evaluation" of the product. They said that AutoDBA sent out a couple of their "experts" who spent three days trying to get it working - installing it, patching it, downloading stuff from all over the web, patching it again, hacking ... and it still barely worked. They begged off the project (and shortly after left the company) when told in no uncertain terms that their "evaluation" needed to be "very positive". Granted, that was over a year ago and the product may have improved since then, but as recently as a few months ago a "registration" for a "trial download" on the web lead only to a marketing call. No thanks... I feel a bit queasy even now just thinking about it.

Re: Replication
Light works with a 9ias application (part of the Light package) to establish the mobile database and application on the mobile client. Once the application and database are downloaded, the database uses Advanced Replication to sync with the master when the clients are brought back to the network. While mobile, Light emulates the oracle server (and potentially the 9ias server) for a single user. You have a master database server connected to the mobile data server (9ias) which handles the interface to the mobile clients (laptops, desktops, what-have-you). Up to 64 mobile clients per mobile server, if I remember the marketing speil right, but we're still at the 4-client dev/test phase. We have staff working on it, with assistance from an Oracle consultant brought in for the purpose. I just deal with the master database. Since we're doing stand-alone, we have to hand-jar the java applications (the jar wizard with Oracle Developer doesn't fit the bill somehow) so application deployment is the sticking point at the moment. We might get an answer this month, but the dev manager is doing the schedule and application details. My understanding is that if you deploy a JSP web app using 9ias, the app can be downloaded and run on the mobile client against the Lite database, and that sort of deployment appears to run smoothly (the examples work). But we're not doing that in this case so I have no real-world experience there. "Ramon E.

Re: Replication
Yes that's how it works, although the volume for 2-3 months might be excessive, if the deltas get large.

Re: Replication
Oracle Lite is designed to do this -- the content-deployment part for standalone applications is a little buggy, but the data deployment and web-app deployment seems to work. We're instituting a couple of applications with this now, and data sync seems to be working fine. Application sync has been getting most of the attention so far, though, as we try to get the programs deployed properly without by-hand intervention. paquette stephane wrote: > Hi, > > We will develop a new system that has a central > database (817/win2000). > >From times to times, some users will worked with a > deployable version of the application in a region > without network connection. > When the users are back, there should be able to > synchronize with the centralized database.

Re: User with less privileges...
I agree on the use of roles - it is the best way to go. However, beware that object privileges granted via a role are NOT in effect inside a definer's rights procedure/package (the default type). This *may* require some investigation and, perhaps, some changes to the application, the privileges of the package owner, the owner of the package, or the package authid, or ... I disagree about granting CONNECT to everyone - grant "create session" instead. CONNECT is actually a pre-defined role with a number of system privileges that most application users do NOT need (alter session, create table, create cluster, create database link, etc.) in addition to the "create session" system privilege. Likewise, I would grant explicit tablespace quotas. Granting RESOURCE is again overkill. Most application users don't need tablespace quotas and even if they do it is usually something trivial (e.g. 1-10 MB) in USERS. The system privilege "unlimited tablespace" (included in the RESOURCE role) is especially dangerous as it includes the SYSTEM tablespace. The "easy way" out is to just grant *everything* to PUBLIC, but it is a very poor choice from any rational security perspective - as you are now discovering. (Oracle preaches this, but doesn't actually practice it themselves!) You will need to do as Bill suggested: 1) Create a set of application-specific functional roles (e.g. CUST_SVC_REP, CUST_SVC_SUPR, CUST_SVC_ADMIN, ...). 2) Grant privileges to roles as appropriate 3) Grant roles to users as appropriate 4) Revoke all (most?) of the application object privileges (and perhaps some others) from PUBLIC The public synonyms are another issue. The don't carry any intrinsic privilege - SELECT, INSERT, etc. still have to be granted to the user or to a role granted to the user. However, public synonyms can be a performance issue and *may* be undesirable for other reasons.

Can you give some ideeas about this problem. I have a schema which contains all the objects for the application. The user owner of the schema is also the application administrator and having more privilleges. The other users can have access to these objects by beeing granted with some special privilleges (like select/update/insert/delete for tables, execute for functions&procedures) Because the user are deleted or added from time to time, the application author decided to grant the above kind of privilleges to the public and also create some public synonyms with the same names as the originals. BUT, my problem is that now I need to create an user (he does not have any relations with the ordinary application users) which I don't want to have any access to the hrowner objects, or just on few. Is this doable working only on this new user or I have to re-create all those synonyms and grant privilleges to every application user and revoke'em from public?

Massive update troubles
I have a data conversion team working on our financial data, prepping it for load into SAP. My concept for the conversion process was to download the flat files, run programs written in C or Perl to transform the data, then use SQL*Loader to load them into relational tables for constraint testing and general analysis, prior to export to the SAP system. At some point early on I lost control, and this mutated into: download the flat files, load them into Oracle, run stored procedures to transform the data through 2 or 3 stages to a new schema for SAP. Still ok, you're thinking. But -- now we're running more than a couple hundred thousand rows at the time, and the developers are still tweaking the process (because the SAP requirements are slowly mutating -- another issue). Frequently the developers will stop a long running query with ALTER SESSION KILL -- this is working but often takes a very long time to roll back. Well, there's the rub -- this is a PC system, and the developers frequently want to make a tweak to their program and re-run it. This puts a tremendous load on what the PC isn't good at -- I/O. So I wind up with a frantic developer on the phone "the Oracle server's locked up!" and sure enough, he's right -- there's so much going on in there you can't do anything that requires a disk access. The evolved response is shutdown abort, startup mount, recover, open. This always works and always takes about 3 minutes. Naturally, I've moved them to their Very Own server, so that this doesn't disrupt other work.

Re: Cursor Sharing
Actually, "CURSOR_SHARING=FORCE" is in the index. ;-)
The short (?) story is that it is a crutch. It can provide some relief from
applications that pour out tons of nearly identical SQL -varying only in
literal values, but it can also cause some significant problems. Also,
there are a lot of bugs with it in all the versions I've used it in (8.1.6.x
and 8.1.7.x). My experience is that it (a) works and (b) helps
significantly in about 30% of the system where I've tried it. Bugs include
things like:
1) "... where col1='X'and col2='Y' (in 8.1.6.x, it substitutes wrong and
generates an error. Fixed in 8.1.7)
2) If the first value in a bind list is a null, it can generate a process
crash with an ORA-07445 (in 8.1.7.1.? at least)
3) Java thin clients can return wrong results (hearsay - from Stan Yelliot)
--- Moral of the story - test it *very thoroughly*!
It can also cause some significant problems, even when it works "correctly".
For example:
*) It cures the most obvious symptoms, but not the disease. Developers
often like to think otherwise and simply continue bad coding practices.
CURSOR_SHARING still doesn't avoid a soft parse. Applications with lots of
literals typically don't reuse cursors either. Partially "masking" serious
design and coding flaws with "magic bullets" like CURSOR_SHARING=FORCE
doesn't actually solve the much larger systemic problems. It is likely to
buy you some time and fewer headaches with thrashing in the shared pool, but
it still isn't very scalable in the long run.
*) *ALL* literals get substituted. This can throw the optimizer off.
Examples:
(1) "where ... and 1 = 2" ("Oh! I don't really need to fetch any rows!"
isn't obvious.)
(2) When a literal causes the optimizer to use histograms well. STATUS_CODE
has possible values of 'OPEN and 'CLOSED'. 99% of all records have
'CLOSED', but 99% of all queries are for 'OPEN'. DBAs would gladly "suffer"
an extra statement with literals rather than suffer a poor execution plan
for 99% of the executions.
I consider using CURSOR_SHARING=FORCE like I would consider using a
tourniquet - its preferrable to sudden death, but it isn't applicable in
every case and is rarely a great long term solution. About three days ago,
I had this discussion with a (very technical) VP. *Everything* is written
with literals. Every literal statement is "prepare()"ed. I explained the
basic issues to him and his preference was not to use it. He wants to
force a resolution of the deeper issues by letting the situation become so
bad soon that it forces a better, more permanent solution - before the
rapidly increasing transaction volume REALLY hits the fan. The
CURSOR_SHARING=FORCE safety valve is something we are reserving as a last,
temporary resort.

Mike,
What is the version of the database? Some versions of 8.1.7 had a few bugs
when this parameter was set to FORCE. I suggest searching Metalink. But it
does work as advertised in later releases. I would also recommend reviewing
Tom Kytes' book to read about his views in using this parameter at the
instance level (my boss is reading my copy, so I can't give you page #s).

Re: SMP on windows2000
My understanding is "according to design" it should do it automatically. My experience is it does, sort of. But the app has to be multi-threaded (by the OS definition, not just context-mapped like Java green threads) for it to ever use more than one processor at the same time. If your single-threaded then for obvious reasons NT will tend to give the next time-slice to the same processor if it's not busy, so it looks like you're stuck on the same one much of the time. With the task manager you can set "processor affinity" on MP machines from the right-click menu of the process. This limits which of the N processors will be used to schedule your process. So you can limit one processor hog to 1 or 2 processors and let the well behaved programs run freely on the others. I don't know how to do this using non-gui tools or to set it up at start time, and your userid has to have permission to do it (essentially you have to be running as the process owner). But it's a starting point for research :).

Re: Rant - Oracle Security
Whenever I talk about database security, I put the emphasis on the much more common accidental damage. If the focus is on preventing external attack, everyone dozes off - few have had (known, at least) penetrations that got to the DB server. However, how many DBAs have NOT had a case of someone calling them and saying something like "Ooops! I dropped the ORDERS table in PROD. I thought I was in DEV." or "Can you restore the 20 records I accidentally deleted?" or ... ... or have never done something themselves like "lsnrctl stop" and discovered that they actually shut down the listener on a node other than the one intended? This kind of stuff probably happens a million times more often than things like SQL injection attacks. Sound security practices make both accidental and malicious damage much more difficult.

Re: Please share your experience with RAC on linux:)
I'm working on getting a new system up on the same (?) platform - Dell PowerEdge 6450 nodes, Dell/EMC FC4700 array, and 9i RAC. Click on the Dell/Linux "Yes" in the certification matrix at: http://www.oracle.com/ip/deploy/database/features/ops/certification/index.ht ml?content2.html 1) The current certification is only for RedHat 7.1 and Oracle 9.0.1, but the Dell rep says that 9.2 should be certified on RedHat Advanced Server within "a month or so". There are some distinct advantages to the new RedHat release - and to 9.2. So far, we are just doing some burn-in and "get aquatinted" with RedHat 7.1 and 9.0.1 RAC. The SA/VP wants to go live ASAP and prefers the current config. After seeing the long list of patches to 9.0.1, some issues with it, and some serious security holes (as mentioned here a month or so ago), I am in favor of testing out 9.2 on Advanced Server and using RH7.1/Oracle9.0.1 only as a fallback position. For one thing, the Oracle-supplied cluster software is (at least) "quirky" in 9.0.1. It is supposed to be significantly better in 9.2. RedHat Advanced Server is supposed to add a lot also - multiple HBAs, a logical volume manager, etc. 2) I use SuSE at home and it is a much smoother Oracle install than any (6.2-7.2)RedHat - at least for Oracle 9.2. SuSE even supplies an "orarun9i.rpm" to configure the kernel, startup scripts, and a bunch of stuff for Oracle9i (or "orarun8i.rpm" for 8i). In addition, there are several very savvy SuSE technical people (e.g. Michael Hasenstein and others) who frequent the SuSE-Oracle mailing list. Oracle on RedHat (any version) seems to always require jumping through a few more flaming hoops. However, RedHat is now in bed with Oracle again - after their little falling out. Even more important is that Dell officially supports only RedHat for RAC. (They also support SuSE, but do not certify it for RAC - or, I think, Oracle in general.) 3) RAC on Dell/RedHat is headed for production "soon", but no production experience yet.

So, what i care is: 1. Which Oracle version to use, release 1 or release 2. Release 1 is certified on many platforms with proper hardware and os, but release 2 is relatively new. But since oracle supports new version and there is maybe less bugs , i prefer release 2 version . Can you share your opnion? 2. Which OS to choose. Suse and Redhat is the oracle prefered version. For RAC/OPS support , is suse better than redhat? Or if i choose redhat, shall i choose the redhat 7.1(the certified version with rac release 1 on Dell machine) or Redhat Advanced Server, or redhat 7.2/7.3? 3. Has anyone here used RAC in production? Especially on Linux/RAC combination? what about your experience? Please share your valuable experience here:), thanks.

Re: Rant
What Ruth describes is "tablespace point in time recovery" or incomplete recovery. I believe the question was about performing complete recovery on a single tablespace while the rest of the database is in use. (I could be wrong in this assumption.) If a single tablespace (other than SYSTEM!) needs complete recovery, then: 1) SQL> alter tablespace BAD_ONE offline; 2) restore corrupted tablespace datafile(s) from backup 3) restore archive log(s) from backup if necessary 4) SQL> recover tablespace BAD_ONE; 5) SQL> alter tablespace BAD_ONE online; While this is happening, object in other tablespaces are fully accessible, except that there may be some issues with objects in other tablespaces that reference objects in the BAD_ONE tablespace (e.g. foreign key constraints referencingtables in BAD_ONE, tables in other tablespaces with CLOBs stored out-of-line in BAD_ONE, tables with primary or unique key constraint indexes in BAD_ONE, etc.). There are a few variations on the theme for step 5 - for example, "recover datafile" perhaps if all the datafiles for the tablespace are not corrupted.

Re: RE: Rant
CDs have some advantages - expense, searchability, and storage space primarily, but... 1) CDs are more difficult to read in bed, on a plane, waiting in the terminal, etc. 2) Books are easier to read, require less equipment, and are more portable than a computer and a CD 3) Try having six different CD manuals open to related sections spread out in front of you - reading them while you work against the database. 4) An open book shows two full pages of information. An open PDF about half a page. 5) I could usually grab a manual and flip through it to the relevant info about 10x faster than a computer search - and with a lot less extraneous (click/point/scroll/type) activity. 6) Highlighters, margin notes, and sticky-note bookmarks don't work at all with CDs I miss hardcopy manuals!

Re: Index questions
Bitmapped indexes will be fast for the queryagainst the 'Y's, but a
bitmapped index may not be appropriate if you are getting lots of DML
activity on this.
Another option is to use NULL instead of the "vast majority" value ('N' - in
this case) and create an index. The nulls won't be indexed, so the index
will be small. This works best when there are relatively few non-majority
values and they are the ones most critically/commonly queried. A hint MAY
be required to make the CBO use the index. This obviousy won't help on
queries against 'N' though. Example, ORDERS table with a STATUS column -
98% 'Closed', 2% ('New' | 'Pending' | 'Whatever...'). Change the logical to
interprete NULL as 'Closed' and create an index on ORDERS.STATUS. Queries
for open orders - ('Closed' | 'Pending' | 'Whatever...') become very fast.

If we have a column of 'Y','N' values, the index will
not help with CBT(usually most of the values are 'N').
My question is : how about bitmap indexes? Should it
help a lot, or just a little bit?

Re: runInstaller - ruinInstaller? RUINstaller?
There have been times when I would have paid extra for (1) a character-mode
installer and/or (2) a reliable and consistent way to create a listing of
EXACTLY what was installed (e.g. the long-defunct "instver").
I think I've installed Oracle with just about every mechanism they've had
since Oracle 5 came out - cpio from tape, custom platform-specific scripts,
a few dozen floppy disks (Xenix & DOS), orainst /c, orainst /m, and
runInstaller. The java-infested runInstaller is one of the worst pieces of
junk that Oracle has ever forced upon the user community. I've made it a
point to express this opinion to several rather senior people at Oracle. A
few - from the technical ranks - have even agreed (off the record of
course). For one thing, "making it easy to install Oracle" makes it far too
easy for the clueless to install it poorly!
Some of the comments like "Any machine that's need to run a production
database should be strong enough to run Java ok" miss the point entirely.
For one thing, not all Oracle installations are on production servers. More
importantly, the vast majority of Oracle installs are NOT done at the system
console. At my last two jobs, we used Exceed Hummingbird - which had quite
a few problems with runInstaller. At my current job, we use Reflection-X.
It seems a bit better - once you learn the quirks. (Hmmm... The first
screen is chopped off at the bottom so the buttons are invisible... Hit
return to go to next screen... Still invisible... Minimize... Click the
minimized icon on taskbar to restore... OK The buttons at the bottom are
visible now...). If you think that sounds like fun, try it over a dial-up
connection.
However, if you really want to experience ruinInstaller (pun intended) in
all its glory, try a cluster install sometime. I spent at least a couple of
man-weeks over the last five years fighting it, trying to diagnose problems,
trying to get it to work correctly - and have NEVER seen it actually work.
A typical cluster-based install with ruinInstaller usually goes something
like this:
loop until entirely sick of it
1) Perform cluster-based install, for which runInstaller reports successful
completion.
2) Go to any node other than where ruinInstaller was run to find that
a) not all the components were copied across
b) only parts (or nothing) got relinked
c) some components were installed, but cannot be recognized by local
ruinInstaller (hence can never be patched or upgraded)
d) all or some combination of the above and/or other major aggravations
3) Fumble around trying to find out why ( with little or no luck)
4) (optional) check Metalink - no help
5) (optional) Call support...
a) "We've never heard of a problem... "
b) Are you sure the server is plugged in? ..."
c) "Can you rcp/rsh between nodes?" (YES!)
d) "Are you sure?" (Well it did copy about half the required components
over... and I can rcp and rsh between nodes as the oracle user - outside
ruinstaller.)
e) ad nausem - perhaps apply some iffy hack that doesn't end up solving the
problem (e.g. "Try it again. When you reach the screen, open
another shell session, convert the .mk file to pig latin, put three
pennies in the Pepsi machine, go out to the parking lot, and perform a Hopi
rain dance. Then select . It should work now.")
6) Wipe all nodes completely clean and start over
end loop
Then... (optional)
Call somebody deep inside the mothership at Oracle and ask them about this
nightmare - and find out that it actually is a known, but largely
unadmitted, problem! Once someone on the OPS development team even supplied
a convoluted deep-geek hack to make it (almost, 99.2%-ish) work.
Finally...
Give up on the cluster install and just install the software individually on
each node. The problem here, on a complex install at least, is in trying to
determine exactly what options were selected everywhere so that you actually
have the same executables on every node. [Checking it with a file dump of
the "Installed Software" isn't very helpful since it seems to generate the
list in pseudo-random order as a hierarchical tree ("diff" doesn't work very
well).]
After the first dozen or so attempts (on several different platforms, with
several different versions of Oracle8 & 8i), I simply decided that I
wouldn't bother attempting another cluster install with ruinInstaller again.

Re: exp73 dumpparam for unlimited extents?
With compress=N, you will get essentially the same mish-mash of extents you had previously - unless you are importing into a LMT. You have basically two options: 1) Pre-create the objects with a storage clause specifying the extent sizes you want - with initial and next the same size. Then import with ignore=Y. Of course, if you drop the users, you will have to recreate them before pre-creating the objects. This is the only option for dictionary-managed tablespaces to get uniform extents. (Hint: imp ... indexfile=somefilename.sql ..., edit somefilename.sql to (1) uncomment the create table statements and (2) modify storage clauses, then run somefilename.sql. If the export is large, you may wish to split this into two parts - one for the tables and one for the indexes and constraints. (It is a little more complicated than it might seem at first, but isn't too bad. One possible approach is to perform one export with rows=Y indexes=N constraints=N and another with rows=N indexes=Y constraints=Y. Details left as an exercise for the reader ;-) 2) Convert the tablespace(s) to LMT(s) with uniform extents - or drop and recreate them as such - prior to the import.

Re: Rollback OPTIMAL setting
I prefer to have OPTIMAL set and deal with "long running large transactions" another way - setting "OPTIMAL" on the developers! Granted, this doesn't work for 3rd party products, but I usually deal with in-house applications. Getting this to work requires: (1) having enough rollback segments, (2) large enough rollback segments that extends almost never occur, and (3) NOT having the "one giant rollback segment for large jobs", and, most importantly, (4) all "batch-lookin' thingies" have to be reviewed by the DBA and optimized, by either the DBA or the developer - or both, until they pass muster. Using this, I rarely seen an ORA-01555 or a rollback shrink (over six months on the systems I'm working with now) - and when I do, I know that it (usually) means that somebody broke rule #(4). When that happens, I track it down and work with the developer to fix it. My experience is that the vast majority of developers are receptive - they actually like to have their code run without problems. Of course, this assumes that the "wasted" disk space for (1) and (2) is not a significant issue. It rarely is, but I work almost exclusively with (essentially) OLTP systems where space is typically less critical than I/O throughput capability and reliability. Usually, we have to add disks for performance rather than space. The database datafile drives are typically 36 GB (less often 18 GB) and are rarely "full", so a GB or two more for rollback tablespace is OK. If I had to operate under the space constraints that many seem to have, I might not set OPTIMAL either. I am looking forward to the day that this "no OPTIMAL" suggestion fades into the "myths and folklore" category. Either because of basic policy changes (e.g. the extents myth), a better Oracle algorithm (e.g. 10i system managed undo???), more intelligently designed batch processes in applications, or the trend towards ever-increasing drive size. Note: All this doesn't mean that I don't understand why so many use the "manual shrink" method. My philosophy differs in that not setting OPTIMAL should be a last resort, not a blanket policy. Don Granaman [OraSaurus] - Original Message - To: "Multiple recipients of list ORACLE-L" <[EMAIL PROTECTED]> Sent: Thursday, June 27, 2002 10:13 AM One of the constant comments regarding rollback segments is not to set optimal.

Re: the ora certified masters cert - finally bloody sick
*** I swear this will be my last post on the issue. If I've offended anyone, they have my most sincere appology. However, I think you have interpreted this wrong. I have never said or implied, nor do I remember seeing anyone else say, that anyone with an OCP is trying to cover up for some deficiency. In the post that you replied to, I said "a few... that waved their OCP around like it was a Nobel prize". These (two) people were - quite obviously. The vast majority of OCPs I've known, including many on this list, are not like that at all. Many got it because it is now a market necessity. Some got it to get an entry-level DBA position. A few that I know got it just to see if they could pass all the exams without any preparation. My problem is not with people who have it, it is with the marketing and hype that has made it mandatory - regardless of level of exerience or anything else. And also with Oracle's most recent greedy exploitation of the situation they created. Will I get it? Probably. (I don't want to be the only one left without it and it looks like Kirti's gonna go for it now. ;-) I've been lucky that my last two jobs I got because someone I had worked with previously called me (a VP and a CTO). However, when and if I have to go looking again, I'll likely need it just to clear the HR checklist hurdle and land an interview. (Unless I get lucky again). Lets see... What do I need to do in the next few months... Finish building and testing a Linux 9i RAC system, set up new software for the MML on every server and migrate all the backups it and a new tape library, diagnose and redesign | tune significant parts of a custom in-house application, move two other internal Oracle systems to bigger servers, spend a couple of weeks reviewing and hardening a client's nine exclusive Oracle8i systems in Chicago and one 8i OPS system in Texas (all but one using literally every option Oracle offers in 8i, including iFS - which I haven't yet had time/motivation to learn), do a security and architectural assessment of a prototype 8i system that another client wants to install in *thousands* of retail locations around the world, do the standard "only DBA in a shop full of developers" development support and production thing, work with the CTO and VP on developing a disaster recovery plan, *perhaps* write a white paper (or two) and a presentation (or two) for OOW 2002, and, oh yeah, ... study for and take about six essentially entry-level DBA exams before Oracle ups the ante again. Sorry, but if I had a choice, I'd rather sleep occassionally instead. I don't really need any more flaming hoops to jump through. I imagine there are a lot of people like me out there who feel the same way. Don Granaman [OraSaurus] - Original Message - To: "Multiple recipients of list ORACLE-L" <[EMAIL PROTECTED]> Sent: Thursday, June 27, 2002 4:33 AM I've been pretty quiet while you all said that the OCP program was pretty worthless because I can see your point. I don't believe that it proves that the holder is technically better than someone has isn't certified. From my point of view, though, I'm convinced that in a tight market it's helped to get me into interviews and that justifies the cost to me. Now, however, you're straying towards calling OCP DBAs liars and cheats and implying that we're dangerous to have on site and I'm sorry but I'm not going to have that. What merit is there in saying "doctors have malpractice insurance and OCP ... should have one too.". Where's the evidence for that kind of witless comment? I originally took my OCP after amassing 10 years of DBA experience. I don't want to get into a pissing contest over this but it grates on me to have it constantly implied that OCP is just there to make up for lack of ability. I'm aware that many of you (Don for instance) have qualified their statements by saying that applies to "a few" or "some" but the implication is still that the majority of OCPs are trying to make up for some sort of technical deficiency. If you don't want to spend the money or the time then that's fine by me. I certainly won't it necessary to criticise you for it.

Re: the ora certified masters cert, yet again
I absolutely am NOT saying that anyone with an OCP is incompetant, a bad person, or any other such thing. Some of the best DBAs I've known were OCP. Some weren't. Some of the very worst DBAs I've known were OCP. Some weren't. I simply think that its main value (other than the totally artifical value of being a common checklist item for hiring authorities now) is to get people to study, learn, and try things out. However, those things don't really require a certificate, ILT classes, or checks made out to Oracle. I agree that this thread is worn out.

Re: the ora certified masters cert, yet again
"What do you hate/find-frustrating about Oracle?" (Let me count the ways... ) That could easily be the most revealing interview question ever conceived! I love it!!! I'm amazed at the number of times someone that is supposedly qualified can't answer a very simple, but unexpected, practical question. I used to always start out with a few "indicator" questions to determine strengths, weaknesses and which way to go. One such was "If you find a file named 'afiedt.buf', how was it probably created?" That particular question caught two very "confident" applicants without the foggiest clue a few years ago. One was the "Oracle Wizard" at his current company. (Seriously. It was the official job title on his business card! ... even though he had been out of college less than a year.) The other was an extremely smug 7 & 8 OCP DBBS who claimed many years of experience and opened our conversation, immediately after the handshake and introductions, with "I'm one of the best Oracle DBAs around - if not THE best.". When I asked this question after a few minutes of pleasant generalities, his smirk disappeared, his jaw dropped and he just sat there staring at me with the best "deer in the headlights" look I've ever seen.

Re: the ora certified masters cert, yet again
The Chauncey certification exam (singular) was a failure because: 1) It didn't parrot/require enough Oracle ILT material 2) Oracle Corp didn't get a big enough cut 3) It was more scenario-based - requiring more understanding and less "knowledge" OCP is more like a "learner's permit". The Chauncey certification was more like a chauffeur's license.

In a separate post Rachel also said Oracle denigrated the prior Chauncey/IOUG tests so it's obvious that Oracle is just using testing and certification as another source of revenue.

The relationship between ORACLE and its user groups have not always been friendly. The OAUG's complaints have made the national press. If my memory serves, and its already been shown to be faulty, the first OOW-Americas was scheduled to be at the same time as the IOUG-A. Corey indicated he was going to see Ellison and explain to him that he couldn't do such a thing, that OOW-Americas would have to be rescheduled.

Re: conferences - IOUG vs OOW
Ditto. There are some great technical sessions at OOW, but the percentage is dramatically lower. Oracle chooses the vast majority of the presentations at OOW and their motivation is quite different from that of IOUG. It seems that every morning at OOW is largely consumed with keynote (e.g. "pump me up" marketing) sessions. One per conference is about all I can take - sometimes even that is too much ;-) In a way its OK though - you can usually just sleep in! [Actually, they seem to have caught on to this (at both conferences!) and now scatter them throughout the day more]. A huge plus is that the crowd at IOUG-A Live! (nee IOUW) is *MUCH* smaller. The possibility of becoming roadkill, as in the inter-session stampede at the Moscone center, doesn't exist at IOUW. There are more/better chances of running into and hanging with your homies from the list. At the IOUG conference (especially), some of the best technical "sessions" are/were on the sun deck, in Starbucks, etc. The roundtables at IOUW are a real plus also. One advantage that OOW does have though is that Oracle usually lets some of their best deep-geeks escape from the bowels of the mothership to go to the conference. I always seem to get chances to drag them off for a little one-on-one time or at least some ad hoc small group discussion. (Its nice to have friends in low places!)

Overlays in Turbo Pascal One of the more challenging aspects of writing Pro*C user exit code for Forms 2.3 on a DOS client running against an Oracle 5 database was trying to link 1,000 or so C functions (at one function per file for modularity) to create a large iapx (?correct name for version?) executable within a segmented 16-bit architecture.

Re: Management Reports
This type of request is entirely too common. The problem is that measuring the "performance" of an Oracle system isn't like measuring the performance of a car in the Indy 500 by timing laps, but that is typically the perception of those asking. At my last employer, we developed application-specific performance monitors - how many orders pending at each stage of the process (approval, submitted, filled, etc.), average processing time (overall and per phase), etc. It was much more useful for identifying problems. Of course this added non-trivial load to the system. The best such "single measure" chart I've ever seen was part of the Precise (nee Savant) Diagnostic Center. It was the response time of the periodic poll to gather information. Other products may have something similar. What are you trying to measure? If it is generic response time, that approach might work. If you don't have anything already, you could write something that pulls some statistics periodically (not too often) and time it on each run, graphing how long it takes. Beware of the Heisenberg uncertainty principle though. The act of detection will likely influence the results. Performance problem may appear and disappear between polls - not showing up. Increasing the frequency of the poll will further denigrate the overall performance. This is a Pandora's box of potential issues. Also beware that an application-independent generic "performance graph" will not always reflect what the users see (e.g. due to application-specific issues - locking, etc.). Generic response time may not be what they want - and probably isn't. One problem with this approach is that often the generic response time is best when the application performance is at its worst! Why? Something else in the stack goes into a catatonic state so that the instance/database is freed up to service the response time query faster. I've seen it happen many times. [Actually, this can be a plus. Scenario: Them: "Quick! Check the database! It seems slow!" Me: "No, its actually running much faster than normal. It seems that the app isn't submitting any/much work."] Another possible alternative is the "Etch-a-Sketch" approach. Give them whatever kind of nonsense appeases them to get them off your back so you can do useful work ;-) Of course, there are potential "issues" with this as well!

Re: Re:RE: Difference Between DBMS/RDBMS
I think that 6.0.x was all there ever was on most platforms. I worked with Oracle on a smorgasboard of Unix-like platforms (AIX, Sun, Xenix, SCO, Unisys s5r4, etc.) all the way through Oracle6 and don't remember ever seeing anything beyond 6.0.36. That could be because either (1) we skipped later 6.x in favor of Oracle7.0.x or (2) what was in memory was swapped to disk and never needed again. ;-) I didn't work with VMS after Oracle 4 (!), but there was at least a 6.2 release on VMS - exclusively I think. [If I remember correctly (unlikely), the VMS release 6.x (x=2?) for the VAX cluster was the granddaddy of OPS].

Re: the ora certified masters cert, yet again
Hmmm... Within the last two days I saw a news blurb that said there are now 113,000 OCPs - up from ~60,000 two (?) years ago. I imagine the a non-trivial number of these went through the entire ILT schedule to get there. I'm not sure exactly what this new OCP ILT requirement is, but I'd venture a guess that it isn't some new course developed entirely from scratch. Look at what the OCM requires in the way of ILT - two additional existing courses (and they aren't very picky about which). So, it sounds like ~26,000 new OCPs per year. True, this isn't likely to cause their stock price to double, but I do think it is much more about revenue rather providing useful certification. How else could requiring a $2,000 ILT class be justified? (My understanding is that it is a class, not a practicum exam). Also, this is just the beginning. I'd bet that future certifications will up the ante on this Oracle ILT requirement. Perhaps by 10i (11i?), the OCP will become more like the Oracle Masters deal - more required ILT courses and simpler exams with heavier emphasis on the GUI tools and whatever esoteric features Oracle is pushing at the time. Think of it this way: Possible Oracle10i OCP requirements: 1) Four weeks of Oracle ILT @ ~$2000 / week for a new OCP 2) Two weeks of Oracle ILT for an upgrade 3) Some exams that are easily passed by regurgitating the ILT - flaws and all Assume 100,000 people want a 10i OCP. Assume that 30% are new and 70% are upgrades. (Wild guesses all.) 100,000 * [(0.30 * 4 * $2000) + (0.70 * 2 * $2000)] = $520,000,000 That doesn't include OCM or OCW (Oracle Certified Wizard) which add to the ILT requirements - and revenue. I can't imagine Oracle promoting anything so heavily if they only break even. (Does anyone else remember the Oracle Developer Programme?

Re: Online vs offline backups
Many of us haven't had the luxury of downtime for cold backups for production systems in many years. Hot backups are quite sufficient. However, whenever I do a cold backup of a dev or test database (and when I could do cold backups in production) I *always* back(ed)up the redo log groups and the control file. Why? 1) You don't HAVE to restore the redo logs - and definitely shouldn't if you have surviving current redo logs and want to recover as much as possible. 2) Its a "no-brainer" to restore and recover a test system to a known state with a cold backup of datafiles, redo log groups, and a control file. Just slap them down, copy redo members & control if necessary, and startup. Very handy for repeating variations of tests from the same consistent known state.

They aren't - unless it exceeds a non-trivial percentage (6%? 7%? more? I can't remember now...) of their income and is "required" (?). This new requirement for OCP is just another in a long line of propaganda/baloney from Oracle in its never-ending attempts to suck up every buck it possibly can. [Oracle likes $. HR likes mindless checklist items. It is a match made in heaven.] I thought that the "need practically any two ILT classes, no matter how irrelevant" 9i OCM was going to be the limit of extending the the greedy grab for OCP bucks - for 9i at least. This isn't about certification anymore (as if it ever was), its about revenue. Since this "new requirement" (for the moment at least) doesn't apply to upgrade from an 8i certification, does anyone know if there is (or soon will be) a new constraint/surprise/ambush limiting that to 8i OCP obtained prior to, oh say, June 15, 2002?

No.), I would go direct at http://www.cabelas.com/ - bottom left side, under "About Us" -> Careers -> DB2/Oracle DBA ... or: http://www.cabelas.com/cabelas/en/templates/community/aboutus/career-details .jhtml?contentId=MIS_DB2_Oracle_DBA&hierarchyId=10708 Don Granaman [OraSaurus] - Original Message - To: "Multiple recipients of list ORACLE-L" <[EMAIL PROTECTED]> Sent: Wednesday, June 12, 2002 3:13 PM Company in Sidney, Nebraska has an Oracle /DB2 DBA position opening on its IT staff.

Re: Cache vs. Oracle
Cache = Mumps++ (Yes, it used to be called "Mumps". Is that an omen? ;-) I worked almost four years in a shop where one of the two most critical systems ran on Cache, but I didn't have anything to do with it. The other 40+ production databases were Oracle - those were mine. My only opinion of Cache is that even their "technical" people are completely full of BS. Once, we had two of them on site for a week on a consulting engagement (tuning). During that time, I heard them telling people how Cache was so much better than Oracle because, among other things, "With Oracle, design and code have nothing to do with performance. Only database tuning by the DBA makes any difference. With Cache, the developer has full control over performance. You don't even need a DBA." Of course, this database was a continual performance nightmare - primarily because the developers "had full control"... and no DBA (they administered it themselves - as per vendor propaganda). Whether Cache is actually capable of decent performance is still a mystery. There were also some other significant issues, but I don't have the details. Be sure that it will actually do what you need before seriously considering it.

Who should I buy Oracle software from?
I have a client that is purchasing additional Oracle db product. The company that the client has worked with for several years turns out to be a "not authorized" reseller. This is the first that I have heard of "not authorized" Oracle software resellers. Are there any reasons why one would purchase from an "authorized" vs a "not authorized" reseller?
