Goal: To restore the database from RMAN backup on a different server by
means of moving the backup pieces and logs over to the new machine and use
Rman to unpack the database files.
Strategy: To restore the database from the RMAN backup pieces into a new
directory locations on the machine and extract the control file and startup
the database.
Some of the steps to setup the new machine.
1) Install oracle 8i
2) install the patch 4.0
3) copy .profile over
4) duplicated the Admin directories for the database to be restored
5) created a big mount /u02/vssppln/ point for all the datafiles and
controlfiles and so on
6) Created a backup mount point to store the RMAN backup pieces and
archivelogs
7) moved the backup pieces and archivelogs to the new machine
8) Setup and confirm connectivity to Rman catalog
9) No mount the database to be on the new machine
10) Launch the Rman command
rman cmdfile=restore_dbsid.rman trace=restore_dbsid.log
Problem... I run this restore from Rman backup...but it gets to processing
the command and gets to the RMAN-03022: compiling command: set and just
hangs...adding another line every 1/2 hour or so...
Anybody seen this or have ideas? I talked to one guy who did have this but
couldn't remember the solution. This is the first time doing this so I might
be missing something simple..
Here is the command in operation
== rman cmdfile=restore_dbsid.rman trace=restore_dbsid.nohup_log

RE: RMAN restore on another server
DENNIS...Thanks for your feedback. Here it is.. (NSF problem??)
1. I am not using Tape only disk backups..
2. I ftp'd the backup pieces to new machine
3. I created a link to duplicate the backup location on the original machine
and other locations as pfiles...edited the init file for new control locations
etc.
4. The controlfile was wrapping in the backup piece same backup command
5. It is an NSF mount point. (Netapp)
Is there a solution with the NFS issue?

Brian - First, congratulations on performing what seems pretty close to a
disaster recovery test. I don't know the specific answer to your problem, so
I'll ask a couple of questions related to hard points I encountered, and
maybe that will strike a cord.
1. You say you connected to your existing RMAN catalog? How does the
catalog know to recover this new database and not the one it backed up?
Maybe it is confused. I found it much simpler to recover from the
controlfile even if I used the catalog to perform the backup. Also in a true
disaster, you may not have your RMAN catalog unless you have another tape.
If you can recover from the single tape with the RMAN backup, then your
offsite tape could get you up and running.
2. Are the backup pieces in the same path as you backed them up? I don't
think that is your problem because that usually gives a clear error.
3. Are you using NFS? I encountered a problem with NFS very similar to
your symptoms. My sys admin assumed there would be only a connection or two
over NFS, so left some stuff default. Come to find out RMAN opens a bunch of
connections.
Sorry, but that is all my brain can think up on Friday.

Goal: To restore the database from RMAN backup on a different server by
means of moving the backup pieces and logs over to the new machine and use
Rman to unpack the database files.
Strategy: To restore the database from the RMAN backup pieces into a new
directory locations on the machine and extract the control file and startup
the database.
Some of the steps to setup the new machine.
1) Install oracle 8i
2) install the patch 4.0
3) copy .profile over
4) duplicated the Admin directories for the database to be restored
5) created a big mount /u02/vssppln/ point for all the datafiles and
controlfiles and so on
6) Created a backup mount point to store the RMAN backup pieces and
archivelogs
7) moved the backup pieces and archivelogs to the new machine
8) Setup and confirm connectivity to Rman catalog
9) No mount the database to be on the new machine
10) Launch the Rman command
rman cmdfile=restore_dbsid.rman trace=restore_dbsid.log
Problem... I run this restore from Rman backup...but it gets to processing
the command and gets to the RMAN-03022: compiling command: set and just
hangs...adding another line every 1/2 hour or so...
Anybody seen this or have ideas? I talked to one guy who did have this but
couldn't remember the solution. This is the first time doing this so I might
be missing something simple..

RE: Oracle and Novell eDirectory LDAP
Stephane - Last week the following message was posted. While it relates to MS AD, rather than Novell, the principles are the same and after all LDAP is a standard -- right? ;-) So you may want to scan the archives for this thread. Several people have expressed interest in this topic, and it seems doable, but nobody has posted a success story. From my meager understanding of LDAP, I think you will have to install and run Oracle Internet Directory, at least to get started, then export an LDIF from OID and import it into eDirectory. Depending on how you intend to use LDAP, you may have to continue to synchronize the two. Dennis Williams DBA Lifetouch, Inc.

RE: RMAN restore on another server
Brian - I think that is the problem -- you can't tell RMAN you are on a
different server. The part I'm not getting a clear picture on is your
control file. For this specific recovery, how is it getting a control file?
Did you move one over from production, or are you waiting for RMAN to cough
it up from the backup pieces? On 8i this tends to be a problem.

Re: rebuilding indexes - sure to cause a ruckus
Hi! Yes Yong I agree with you, that rebuilding may be beneficial in some cases, especially some tables/indexes become either logically or physically read only (btw, I was not speaking about coalescing in my post, it's a different story anyway). But the point I wanted to make is that single query's speed (LIO amount) right after rebuilding index doesn't usually give us enough information to determine whether overall system speed will go better in long term. When you have rebuilt an index, it becomes more compact, causing more recursive operations for block splits and perhaps index height changes in the future. Also, in heavily loaded 24x7 environments with no real low-peak time, the additional CPU, IO and brief exclusive lock usage may cause more harm than it gives benefit. And often this benefit is only short term in regular OLTP systems. But in some cases, as when you've deleted a number of rows from your table or done a lot of updates and you never expect these keys to be back in the index, a rebuild can be justified. Tanel. - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Friday, December 05, 2003 10:29 PM Tanel, I think you're saying a query almost always runs faster right after the index rebuild and there's no point in finding the criterion whether to rebuild an index. (What is 42?) Some time ago I posted a message somewhere else showing a case where rebuilding or coalescing an index may be benefitial. A data warehouse is found to have some data errors. Deletes and updates are done. Then the database goes to mostly read-only again, and will last for a month or quarter. Then shrinking frequently used B*Tree indexes is a good idea. Now I'd like to add one more criterion as a result of reading Jonathan Lewis' dbazine article and email with him (errors are mine): the index is full scanned, or if range scanned or unique scanned, the index selectivity has to be fairly low (but not too low for the index to be ignored by CBO). In a typical working environment, a data warehouse does have plenty of relatively quiet period. I worked on a monthly data load project at an insurance company. I remember we rebuilt a partitioned IOT (one partition at a time) and fast full index scan (certain partitions) did run faster. There're some errors in Don Burleson's dbazine article (e.g. pct_used in dba_indexes) and Mike Hordila's Oramag article (structurally unbalanced index). But one thing alluded to in there is important: study Oracle performance problems as scientific research. You said setting _wait_for_sync to false improves performance. That's a fact. We can only explain and analyze it but not deny it. Similarly, when Mike says queries run 10 to 50% faster after index rebuild, we can't deny unless we find his measurement is wrong. Wouldn't it be nice if Oracle researchers write articles with sections like Abstract - Experimental - Results - Discussion in that order? Yong Huang Tanel Poder wrote: There's no point of arguing about whether a query ran faster right after you rebuilt your index. Nor there is no point in finding some ultimate algorithm for finding the point of index rebuilding, we all know the answer - it's 42. Instead, a long stress test has to be done, e.g. running 10 millions of continous transactions and queries (simulating real life). Do one 10M without rebuilding indexes in the meantime, measure total execution time, IO amount, CPU usage, segment sizes etc. Then restore your database back to starting point and do the same test again with regular index rebuilds during the operations (online or taking users offline, depending on environment type). And then measure the same statistics, especially total execution time. Note, that statistics and time also for rebuilding indexes should be accounted in totals, because in real life they don't just disappear somewhere as in some simple-minded tests.

Re: Oracle Data Guard
Hi All, can any one let me know kindly the following info. 1) Has any one used the Oracle 9i Data Guard? Yes, physical standby and successfully. 2) If yes then, is there any performance impact on Target/Source server database. Your database has to be in archivelog mode, but when you are thinking such solutions as DG, then you probably are already running archivelog anyway. If you run in maximum protection or maximum availability, yes there is. The impact depends mainly on network connection between primary and standby(s) and the speed of redolog disks. You could tune these by using faster network, enabling jumbo frames and SDU size if using Gbit ethernet, also setting lgwr and log apply processes priority higher than others. 3) any drawbacks using Data Guard. You should set your database or critical tablespaces to force logging mode in order to transfer all changes to standby in physical standby.

RE: CPU Capacity Planning
Thanks a lot, Cary.
Yes, this sentence on p.248:
As long the execution of each business function can
be expressed in terms of an LIO count, you can
translate the queueing model's output in terms of
business function response time and throughput
was the one I marked as something to go back to, as I
didn't really understand it.

Note that you can avoid even using queueing theory

performance curve for each resource on the system.
You can learn the

Thanks for the clarifications, Cary.
With regards to a hardware sizing - how do LIOs fit
into queueing theory? Let's say I can come up with
something like:
#CPUs required = Sum( LIOs(Bus.Tx i)) /
(10,000*clock rate/100)
where i={Bus.Tx 1..n}
[on a projected box that haven't been bought yet, it
might be a little difficult to estimate the
denominator, ... and on the existing one I guess I
have to get hold of Jonathan's paper to learn how
this
can be done]
..but in any event for forecasting purposes, how
queueing effect might be taken into account here?
Let's say I measured Sum( LIOs(...)) for a 50 users
in
a unit testing environment and I am told that
production would be 10 times more than that, what do
I
do?
Thanks,
Boris Dali.

Thanks a lot for the reply, Cary. Yes, your
explanation makes all the sense in the world even
though it is precisely the weighted average
approach
that I've seen on some capacity planning
spreadsheets.
Two additional questions if I may, Cary.
Would it be correct to say that when I throw
additional users on a system it is only queueing
component of a response time that climbs up, while
service time stays the same?
[Cary Millsap] Sort of, but not exactly. There
are
lots of scalability
threats that begin to manifest in reality when you
crank up the load.
For example, you'll see latch free waiting on
applications that parse
too much, but only at higher user volumes (never
in
unit test). You can
consider the new appearance of latch free events
to be a type of
queueing if you want, but it's really not queueing
in the sense of a
simple CPU queueing model.
If that's true, than does
it matter how I measure service time of my Bus.Tx1
-
on a loaded system where hundreds of users run
this
operation or when nobody executes it all? Also is
it
important to have the other two operations -
Bus.Tx2
and Bus.Tx3 - running concurrently (as they would
in
a
real life) for the c measurements?
[Cary Millsap] You'll put yourself at risk if you
simply try to use a
queueing model to extrapolate big-system
performance
from data collected
in a unit testing environment. It's because of the
potentially
out-of-model scalability threats.
In other words assuming I have an identical
replica
of
a production environment where I am the only user
-
would service time/rate measured there be
applicable
for a loaded system with heterogeneous workload?
[Cary Millsap] ...Only if you your production
environment doesn't
trigger any new serialization issues that weren't
visible on your unit
test env.
And another stupid question.
Knowing individual business tx. characteristics
(response time, number of CPUs required to comply
with
SLA requirements, average utilization per CPU,
etc),
how does one go about sizing the box in terms of
the
overall system required CPU capacity? Or put it
another way - what do I tell a hardware vendor?
That is, if what comes out of a queueuing exercise
is:

RE: RMAN restore on another server
Brian - My sys admin pleads amnesia on the NFS problem. My recollection was
that it was misconfigured or had a default configuration that expected only
a couple of connections and RMAN actually opens MANY file connections. My
specific symptoms is that RMAN would create the first few data files and
then just stop. Oracle Support made me take NFS out of the mix and then
everything worked.
In your case, I am also concerned about the control file. I was unable to
get 8i to create the control file from the backup although others on this
list reported success with that. I would feel better if you said that you
separately backed up the control file at the end of the RMAN backup, and
manually moved that control file into place on the test system. At least you
would eliminate that as the problem.

Brian - First, congratulations on performing what seems pretty close to a
disaster recovery test. I don't know the specific answer to your problem, so
I'll ask a couple of questions related to hard points I encountered, and
maybe that will strike a cord.
1. You say you connected to your existing RMAN catalog? How does the
catalog know to recover this new database and not the one it backed up?
Maybe it is confused. I found it much simpler to recover from the
controlfile even if I used the catalog to perform the backup. Also in a true
disaster, you may not have your RMAN catalog unless you have another tape.
If you can recover from the single tape with the RMAN backup, then your
offsite tape could get you up and running.
2. Are the backup pieces in the same path as you backed them up? I don't
think that is your problem because that usually gives a clear error.
3. Are you using NFS? I encountered a problem with NFS very similar to
your symptoms. My sys admin assumed there would be only a connection or two
over NFS, so left some stuff default. Come to find out RMAN opens a bunch of
connections.
Sorry, but that is all my brain can think up on Friday.

Goal: To restore the database from RMAN backup on a different server by
means of moving the backup pieces and logs over to the new machine and use
Rman to unpack the database files.
Strategy: To restore the database from the RMAN backup pieces into a new
directory locations on the machine and extract the control file and startup
the database.
Some of the steps to setup the new machine.
1) Install oracle 8i
2) install the patch 4.0
3) copy .profile over
4) duplicated the Admin directories for the database to be restored
5) created a big mount /u02/vssppln/ point for all the datafiles and
controlfiles and so on
6) Created a backup mount point to store the RMAN backup pieces and
archivelogs
7) moved the backup pieces and archivelogs to the new machine
8) Setup and confirm connectivity to Rman catalog
9) No mount the database to be on the new machine
10) Launch the Rman command
rman cmdfile=restore_dbsid.rman trace=restore_dbsid.log
Problem... I run this restore from Rman backup...but it gets to processing
the command and gets to the RMAN-03022: compiling command: set and just
hangs...adding another line every 1/2 hour or so...
Anybody seen this or have ideas? I talked to one guy who did have this but
couldn't remember the solution. This is the first time doing this so I might
be missing something simple..

RE: Alert Log
This is from the Oracle 8i Administrators Guide for Windows:
Oracle8i for Windows NT background threads use trace files to record occurrences and
exceptions of database operations, as well as errors. Background thread trace files
are created regardless of whether the BACKGROUND_DUMP_DEST parameter is set in the
INIT.ORA initialization parameter file. If BACKGROUND_DUMP_DEST is set, the trace
files are stored in the directory specified. If the parameter is not set, the trace
files are stored in the ORACLE_BASE\ADMIN\DB_NAME\BDUMP directory.
This is the same information from the Oracle 9i Administrators Guide for Windows:
The alert file is named SIDALRT.LOG and is found in the directory specified by
parameter BACKGROUND_DUMP_DEST in the initialization parameter file. If
parameter BACKGROUND_DUMP_DEST is not set, then file SIDALRT.LOG is
generated in ORACLE_BASE\admin\db_name\bdump. Alert files should be
deleted or archived periodically.

Thanks much, Ken Janusz, CPIM
RE: PERL?
The difference that has affected me the most in writing utility scripts is that PERL can talk to the database like using a telephone. Ksh must talk like using a walkie-talkie; that is, each side of the conversation must talk then release the push-to-talk (PTT) button before the other side can talk. Using a small amount of cleverness (which is good, because that's about how much I have) in ksh, you can program around most of the communication limitations. For example, to deal with sqlplus getting stuck for one reason or the other, you can run the subsection of the script in the background (as a ksh job). Then you check on the job later in the script. If the job is still there longer than it should be, the script can kill the job. THEN, for good measure, look for sqlplus (and possible another ksh that got forked by the script) with parent process ID (PPID) of me and kill them. This is similar to the other side failing to release the PTT button. Unlike PERL, which can maybe yell into to telephone to wake the other side up, ksh must launch an artillery shell onto the other guy which, in a rather violent manner, will cause him to release the PTT button (well ... actually .. the PTT switch kind of got blown up too). Then, depending on the situation, retry the sqlplus or conclude that something is wrong. That being said, ksh is so easy to use and so handy, that I still use it for automating database management and monitoring. I'm sure a big part of that is because I learned shell, sed, awk, etc. programming before perl was standard equipment on Unix boxes. I suppose if you are starting from the beginning, then the way to go would be perl. But you can still do a heck of a lot with ksh (the REAL ksh; not the POS public domain ksh that tends to show up with linux). For an excellent book on getting started with this, go to Amazon and search on Mark G. Sobell (or just Sobell). Here's a tinyurl link to what I think is still must-have book. Even though a lot of it is outdated, the sections on getting around in Unix and shell scripting are still entirely relevant. http://tinyurl.com/y8x6 (Note that the used book sellers are just about giving away the book) There is also a BSD version of the above book. And you want to get O'Reilly's book on Sed and Awk. Those should get you going down the wonderful world of shell scripting ... which is the ORIGINAL, and still great, Rapid Application Development. -Original Message- I've read a lot about PERL on this list. And, I am wondering what can you do with PERL that you cannot do with SQL*Plus, PL/SQL or Unix shell scripts?

RE: PERL?
Hey Mladen, Weren't you going to be taking a look at Python too? (Around Thanksgiving as I recall.) I'd be interested in your feedback on it as well. My take is that Python is powerful yet easy to learn, it's much more productive than Java and is still quite scalable. Like Perl it's a great multi-platform scripting/glue language and shares many of its advantages but unlike Perl, it's been object oriented from the start. There is some looseness to its OO but the Python community touts that as an advantage. ;-) We have a Python story here where we host our software for the majority of our customers. While we perform most of the administration for our customers we also allow them to admin some stuff via a web app developed in Python. This app was developed under an accelerated schedule with a 3 man team headed by a brilliant computer science PhD dweeb who really doesn't have to work for a living but chose to work with us just for the fun of it. One of the things our customers can do is perform upgrades of their app and this entails things like creating complete database schemas, Oracle backups and creating/dropping tablespaces among other things. (Kind of scary from a DBA control freak perspective.) Shortly after this web app went production, one of the developers was tragically killed, another developer who was an intern went back to school, and the PhD dude went on to be a university professor so the app was kind of dumped on my department consisting of a dozen admin type dweebs. We had to learn Python to maintain this mission critical app in short order. Not only were we able to quickly come up to speed to support the app, we have since greatly enhanced it to where it's become central to much of our SysAdmin/DBA duties. One reason for this successful transitions was the virtue of Python. Several in the department (myself included) were Perl literate beforehand and there is now unanimous consensus that we could not have had as good transition if the app had been written in Perl and we are glad Python was forced on us because the readability of Python code makes it MUCH more maintainable. Besides being DBA I've now done enough in Python that I am part DUHveloper. With socket programming and XML I've been able to transact between databases. (Which is definitely more sophisticated I/O than PL/SQL is capable of.) I've also used Python to develop a web server and I'm even thinking about replacing some Apache usage with my own web server code. Well that's our story and there's more to Python than I can cover here so as soon as hunting season is over I'm going to resume preparation for my upcoming IOUW presentation titled, Python, Oracle and the Meaning of Life. Hope to see some of you there.

In fact, perl stands for Practical Extraction/Reporting Language. That means that perl is excellent for producing all kinds of reports. In fact, it has a part called formats which is, in fact, a small report writer and can be used to produce beautiful reports very quickly and with minimal effort. The next very useful feature is an extremely versatile regular expression engine which can do whatever awk sed can do and more. That, of course, is ideal for parsing all kinds of regular expressions, like, for instance, parsing alert.log. Perl , as I've said before, is a general purpose programming language with pointers (all right, all right, the name is references, but those are really pointers) , which makes for an exceptionally powerful combination. Last, but not least, there is a huge treasure chest called CPAN (http://cpan.perl.org) which contains vast number of modules. In case of emergency, it's really easy to find something useful. One other thing worth mentioning is that perl has bindings and modules which make it possible to work with many databases, Tk, Gtk, HTML and almost anything conceivable (OLE, ODBC, ADO and other MS perversions included). There are two problems with perl. One is that perl is a huge language with so many intrinsic and important elements that it is really hard to learn the whole language. A title of a perl master should be an equivalent of a PhD. Another problem is a serious inadequacy of perl syntax for OO. Perl doesn't have classes, abstract classes, private/protected/public interface, templates, exception throw/catch mechanisms or some other things that we know and love. Perl's OO model is based on something called module, essentially a program unit and a very weird function named bless. This function plays a vital role in object construction and, it is done from up down to the ground instead of doing it from the ground up. Bless takes a pointer (reference) and blesses it to the pointer to a member of a given
RE: RMAN restore on another server
Dennis and all,
I have no problem getting the controlfile... I just comment out the SET commands to
change the directories of the dbfs...and I replicate the control according to the init
file specifications.. So This operation actually extract the controlfile out of the
backup piece so I know the location and connections are working fine.
But since the controlfile is backup and I am restoring it with the same RMan command I
think I should have no problem.. I know other DBAs.. run this same script and restore
the database on another server with no problem if the controlfile is restored before
the database is restored and recovered.

Re: I/O error offlines a datafile
It's review time, so everything you do is wrong, as a cost saving measure. Any half way competent member of damagement can tell you that.In this particular case though, you could have recovered the datafile online. You should have offlined the tablespace, restored the datafile and recovered the datafile. Restarting the database was not not necessary. Also, one of my religious rituals is to perform a checkpoint after the tablespace has been successfully brought online. The reason is to record the new timestamp to the control file and make sure that all files have the same timestamp (checkpoint process updates file headers during checkpoint).

Re: I/O error offlines a datafile
Mladen, Thank you very much for your suggestion. I tried exactly that - offline the tablespace and restore the datafile and - guess what? - it failed because of the lock being held against the datafile. That is what lead me (and the Oracle support guy) to bounce the database. Now I may be less than half way competent member of damanagement (whatever it means), but based on your advice you may be not much better. In the future if you can't refrain from isults, please do not reply to my posts. I'm asking for help and advice, not an insult.

Perl is a full flege programming language, it can do almost anything
such as Java or C++ can do. SQL*Plus or Shell is very limited in terms
of functionalities.
Besides, Perl is portable language. Perl code runs on almost any
platforms.

Regardless of whether or not it works, download it and the other tools like

Re: dc_used_extents ,dc_free_extents and dc_histogram_defs
Well, once upon a time, in a land far, far away, there was Oracle V6 with something called TPO, which was essentially row locking + PL/SQL V1 (no stored procedures). My guess is that Cary Millsap, Anjo Kolk, Steve Feuerstein and Howard Rogers know a thing or two about the Jurassic period in the database development. BTW, that was also when buffer hit ratio was invented. The entries that you see are remnants from oracle v6, together with the table called V$ROWCACHE and are both religiously maintained for the compatibility reasons, because Oracle Corp. doesn't want to disappoint all those who are still running V6. Even compatibility with V5 is still maintained. In Oracle 5.1.22, dictionary views weren't called user_tables and user_objects, they were called tab (user_tables) and cat (from CATALOG, replaced with USER_OBJECTS). The term CATALOG was directory command on Apple IIe (6502, later Z80) with 100k floppies, computer immensly popular at the time, and I believe that is why the first implementation of user_objects was called catalog. Now, let's fast forward to the present time and Oracle 9.2.0.4. Do Select * from tab and select * from cat. You'll be surprised.

Most of the databases are running fine, but one insists on looking for the default file name, despite my having provided filename=filename parameter to orapwd. I can't find anything that is supposed to clue it in in this circumstance, and recreating the password file doesn't really so any good either. Every time I try to start the database using the pfile, it complains about wanting the orapwd file... All of the other databases are happy enough with what I did.

RE: RMAN restore on another server
why not use the RMAN duplicate database process. that sounds like what you
are trying to do. Have you ever let the script run to completion? Maybe its
slow for another reason. I have used duplicate database on Solaris many
times with great success.

Dennis and all,
I have no problem getting the controlfile... I just comment out the SET
commands to change the directories of the dbfs...and I replicate the control
according to the init file specifications.. So This operation actually
extract the controlfile out of the backup piece so I know the location and
connections are working fine.
But since the controlfile is backup and I am restoring it with the same RMan
command I think I should have no problem.. I know other DBAs.. run this same
script and restore the database on another server with no problem if the
controlfile is restored before the database is restored and recovered.
Here is the restore controlfile script and resulting log file

Re: dc_used_extents ,dc_free_extents and dc_histogram_defs
Larry Ellison has publicly stated that his goal is to produce a database with less then 100 tunable parameters. Allegedly, he came rather close with 10g. As far as 10g is concerned, I'm rather disappointed with the marketing hype being created with oracle not making an early version available. I don't plan on migrating to 10g until I learn it well and if some oracle sales guy tries to exert pressure on me to migrate, he will get a very stable sign used by English archers after the battle at Agincourt to signify that they still have all the fingers needed to operate a longbow.

My guess is that Cary Millsap, Anjo Kolk, Steve Feuerstein and Howard Rogers know a thing or two about the Jurassic period in the database development. BTW, that was also when buffer hit ratio was invented. The entries that you see are remnants from oracle v6, together with the table called V$ROWCACHE and are both religiously maintained for the compatibility reasons, because Oracle Corp. doesn't want to disappoint all those who are still running V6. Even compatibility with V5 is still maintained. In Oracle 5.1.22, dictionary views weren't called user_tables and user_objects, they were called tab (user_tables) and cat (from CATALOG, replaced with USER_OBJECTS). The term CATALOG was directory command on Apple IIe (6502, later Z80) with 100k floppies, computer immensly popular at the time, and I believe that is why the first implementation of user_objects was called catalog. Now, let's fast forward to the present time and Oracle 9.2.0.4. Do Select * from tab and select * from cat. You'll be surprised. For all those still running V5.1.22 with forms 2.0 and 2.3, the world is not over yet.

RE: PERL?
One BIG advantage of Perl is DBI. Via shell you can't use bind variables which sometimes come in handy. An admin dweeb here developed a monitoring shell script that executed 5500 queries an hour each using literals instead of bind variables resulting in shared pool fragmentation and server errors. When the same monitoring was rewritten in Python the load on the server was dramatically reduced. (It could have been done in Perl with the same result.) The usage of literals could have been avoided with PL/SQL but there was also a need for significant file reads, file writes and email so using shell and PL/SQL was cumbersome at best. (Besides, the admin dweeb didn't know PL/SQL.) Another plus is that your oft used routines can be portable between Windoze and *nix. I guess the point is this: Many times you need greater programming power than afforded by shell scripting. If you can easily and productively perform everything that you can do in shell scripting with a complete programming language like Perl or Python then you're one step ahead of the game. Otherwise you may be lamenting limitations. So the remaining challenge is merely learning a programming language that works for you. Steve Orr Bozeman, Montana -Original Message- [EMAIL PROTECTED] Sent: Monday, December 08, 2003 9:14 AM To: Multiple recipients of list ORACLE-L The difference that has affected me the most in writing utility scripts is that PERL can talk to the database like using a telephone. Ksh must talk like using a walkie-talkie; that is, each side of the conversation must talk then release the push-to-talk (PTT) button before the other side can talk. Using a small amount of cleverness (which is good, because that's about how much I have) in ksh, you can program around most of the communication limitations. For example, to deal with sqlplus getting stuck for one reason or the other, you can run the subsection of the script in the background (as a ksh job). Then you check on the job later in the script. If the job is still there longer than it should be, the script can kill the job. THEN, for good measure, look for sqlplus (and possible another ksh that got forked by the script) with parent process ID (PPID) of me and kill them. This is similar to the other side failing to release the PTT button. Unlike PERL, which can maybe yell into to telephone to wake the other side up, ksh must launch an artillery shell onto the other guy which, in a rather violent manner, will cause him to release the PTT button (well ... actually .. the PTT switch kind of got blown up too). Then, depending on the situation, retry the sqlplus or conclude that something is wrong. That being said, ksh is so easy to use and so handy, that I still use it for automating database management and monitoring. I'm sure a big part of that is because I learned shell, sed, awk, etc. programming before perl was standard equipment on Unix boxes. I suppose if you are starting from the beginning, then the way to go would be perl. But you can still do a heck of a lot with ksh (the REAL ksh; not the POS public domain ksh that tends to show up with linux). For an excellent book on getting started with this, go to Amazon and search on Mark G. Sobell (or just Sobell). Here's a tinyurl link to what I think is still must-have book. Even though a lot of it is outdated, the sections on getting around in Unix and shell scripting are still entirely relevant. http://tinyurl.com/y8x6 (Note that the used book sellers are just about giving away the book) There is also a BSD version of the above book. And you want to get O'Reilly's book on Sed and Awk. Those should get you going down the wonderful world of shell scripting .. which is the ORIGINAL, and still great, Rapid Application Development. -Original Message- I've read a lot about PERL on this list. And, I am wondering what can you do with PERL that you cannot do with SQL*Plus, PL/SQL or Unix shell scripts?

Oracle, GPG, PGP, Java...
Hi folks, I'm looking for some kind of library or such that would allow me to decrypt PGP/GnuPG encrypted content from SQL. Something allowing me to do something like this: SELECT decrypt([private key passed in from application code], field) from ... The current solution we have (in Perl) is something like this: - Select out the encrypted value - Exec() the gpg command-line utility, supplying the private key - Do something with the decrypoted data. We use the GnuPG.pm module, which is really just a wrapper around an exec() (yuk). I'd like to be able to eliminate all the exec madness, and use something a little closer to the database. I was glancing at Chapter 22 in Feuerstein's Oracle PL/SQL Programming (3rd. ed.), and thought it might not be too hard to find an existing Java library that can manage the decryption, and call the Java library from PL/SQL, as discussed in that chapter. Has anybody else done anything like this? Any Java libraries that can manage PGP decryption? I found one here: http://www.cryptix.org/products/openpgp/index.html#download but wanted to ask the list's opinion to see if there was anything else out there. I would assume I could also call native C libraries from PL/SQL via some voodoo which I haven't explored yet, and if needed would be open to something like that as well, but though Java might be a gentler path to start with.

different implementations of the Towers of Hanoi solution, each in a different
language. Since he didn't have one in PL/SQL, I decided to write one.
Here it is:
create or replace package hanoi
is
from_peg constant number := 1;
to_pegconstant number := 3;
using_peg constant number := 2;
procedure play(n number);
end hanoi;
/
create or replace package body hanoi
is
procedure do_hanoi(n number, from_peg number, to_peg number, using_peg number)
is
begin
if(n 0) then
do_hanoi(n-1,from_peg, using_peg, to_peg);
dbms_output.put_line('move '||from_peg||' -- '||to_peg);
do_hanoi(n-1, using_peg, to_peg, from_peg);
end if;
end;
procedure play(n number)
is
begin
do_hanoi(n, from_peg, to_peg, using_peg);
end;
end;
/
This concludes this public service announcement. We now return you to our regularly
scheduled programming.

Re: Oracle Data Guard
Hi Tanel, Much appreciated, The fact is I am interested in Logical standby rather than physical. Our 30-50% of our Production data needs to be replicated to another database and where they will have their processing and batches. Now We didn't go to Snapshot because It is on multiple tables (where we didnot have PK's and many tables) and due to performance issue I didn't want to use Snapshots (they did not want any tables to be truncate before being loaded even via snapshots). The best option I think is Logical Standby Database. Or Can you please suggest me any other means. Replication should be quicker like once in every 20 minutes, Even Transportable tablespacs does not work here since they need all tables to 24*7. Any suggestion would be more helpful. with thanks, Vi. --- Tanel Poder [EMAIL PROTECTED] wrote: Hi All, can any one let me know kindly the following info. 1) Has any one used the Oracle 9i Data Guard?

Re: rebuilding indexes - sure to cause a ruckus
Ouch, I gotta take a day off to read this one ;) Tanel. - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Monday, December 08, 2003 11:29 PM Hi Yong, Saying there are a few errors is being a little kind to Don's Inside Oracle Indexing article. In part, these are some of the issues I raised directly with Don in a number of emails (warning somewhat on the longish side ;): a.. There are no such things as star indexes. Star joins, yes, star transformations yes, but not star indexes ? b.. I still disagree with your description of b-tree indexes being complex and difficult to understand, but then again this could just be my personal perception (check out http://groups.google.com/groups?q=g:thl3498916429ddq=hl=enlr=ie=UTF-8se lm=ant%259.39604%24jM5.100537%40newsfeeds.bigpond.comrnum=47 where I have a sample demo on how to investigate the workings of b-tree indexes.) However, by understanding them and a how they function, the question of whether or not they need rebuilding no longer needs to be debated. It becomes easily apparent under what conditions indexes could benefit from a rebuild. I'll expand on this later but I would suggest those that debate, those that really don't know when a rebuild is justified and just rebuild in the hope it might do some good are those that really don't understand how indexes function. Knowledge is the key that unlocks the door of doubt and those without the key fumble aimlessly and prod around in hope... c.. Your subsequent quote There is enough anecdotal evidence that index rebuilding has helped some systems perform better, and I also have no doubt that there is no scientific basis for the claim is a nonsense. Of course one explain in scientific terms such performance improvements, I can only suggest that you unfortunately can't. Oracle is not some magic piece of software and it doesn't run on some magical pieces of hardware. Any suggestions to the contrary are not helpful to anyone. d.. I still disagree with the double the block size, halving the logical reads must be a good thing argument. It's a path that could lead to a very disappointing conclusion (read cliff edge). Indexes prefer large block sizes true but if the underlining storage file-system is not tuned to read (or write) these larger block sizes efficiently, then the whole thing is counter productive. You've been warned ... e.. Your description of PCTUSED is still wrong. There is no PCTUSED for indexes so it really shouldn't be misleading to confuse a non-existing index attribute with the amount of used space as documented in INDEX_STATS... f.. Including in your criteria for rebuilding an index btree_space being greater than a block is redundant when listed with the other criteria. It is fundamentally impossible for an index with 4 levels or more to consist of a single block, so why mention it. It just adds confusion and is silly. The DBA who swears by this criteria (which I noticed has changed in this draft ;), how do they make such a claim? It's one thing to swear, it's quite another to prove. Your table that lists average rows and blocks per different index levels shows that those indexes with a leaf row length of 500,000,000 and with 100,000 blocks require 4 levels. How does rebuilding such indexes with no subsequent change in index level improve performance ? I mean, large indexes need more levels right, so rebuilding them all the time and keeping the levels unchanged only to rebuild them again because they're still 4 or more levels seems like a pointless, never-ending exercise in futility. To rebuild an index that actually results in a reduction in it's level generally requires a drastic reduction in it's data volume due to the orders of sizing magnitude that a new level represents. More on this and the other so-called rebuild criteria later but the current level of an index is not a criteria for a rebuild. A level 3 index could conceivably be rebuilt to just a level 1 (if there were heaps and heaps of deletions) and a level 5 index could be rebuilt to stay at level 5. Which index has benefited . g.. Criteria for a rebuild: or the total length of deleted is 1 block makes no sense whatsoever. Nearly all indexes would have a total length of deleted than 1 block meaning nearly all indexes need rebuilding. I don't think so ... h.. Your discussion on the clustering factor affecting the likelihood of requiring an index rebuild is still flawed, however interestingly, you've now given an example on why this is the case. However, you've still come to the wrong conclusion !! Firstly, you're incorrect in your example to say that a 1,000,000 row table with a clustering factor of 1,000,000 has it's rows in the same order as it's index although I guess this could be a typo. Regardless, if you delete all last_name beginning with a K, you are going to delete consecutive leaf nodes

However, by understanding them and a how they function, the question of whether or not they need rebuilding no longer needs to be debated. It becomes easily apparent under what conditions indexes could benefit from a rebuild. I'll expand on this later but I would suggest those that debate, those that really don't know when a rebuild is justified and just rebuild in the hope it might do some good are those that really don't understand how indexes function. Knowledge is the key that unlocks the door of doubt and those without the key fumble aimlessly and prod around in hope... c.. Your subsequent quote There is enough anecdotal evidence that index rebuilding has helped some systems perform better, and I also have no doubt that there is no scientific basis for the claim is a nonsense. Of course one explain in scientific terms such performance improvements, I can only suggest that you unfortunately can't. Oracle is not some magic piece of software and it doesn't run on some magical pieces of hardware. Any suggestions to the contrary are not helpful to anyone. d.. I still disagree with the double the block size, halving the logical reads must be a good thing argument. It's a path that could lead to a very disappointing conclusion (read cliff edge). Indexes prefer large block sizes true but if the underlining storage file-system is not tuned to read (or write) these larger block sizes efficiently, then the whole thing is counter productive. You've been warned ... e.. Your description of PCTUSED is still wrong. There is no PCTUSED for indexes so it really shouldn't be misleading to confuse a non-existing index attribute with the amount of used space as documented in INDEX_STATS... f.. Including in your criteria for rebuilding an index btree_space being greater than a block is redundant when listed with the other criteria. It is fundamentally impossible for an index with 4 levels or more to consist of a single block, so why mention it. It just adds confusion and is silly. The DBA who swears by this criteria (which I noticed has changed in this draft ;), how do they make such a claim? It's one thing to swear, it's quite another to prove. Your table that lists average rows and blocks per different index levels shows that those indexes with a leaf row length of 500,000,000 and with 100,000 blocks require 4 levels. How does rebuilding such indexes with no subsequent change in index level improve performance ? I mean, large indexes need more levels right, so rebuilding them all the time and keeping the levels unchanged only to rebuild them again because they're still 4 or more levels seems like a pointless, never-ending exercise in futility. To rebuild an index that actually results in a reduction in it's level generally requires a drastic reduction in it's data volume due to the orders of sizing magnitude that a new level represents. More on this and the other so-called rebuild criteria later but the current level of an index is not a criteria for a rebuild. A level 3 index could conceivably be rebuilt to just a level 1 (if there were heaps and heaps of deletions) and a level 5 index could be rebuilt to stay at level 5. Which index has benefited . g.. Criteria for a rebuild: or the total length of deleted is 1 block makes no sense whatsoever. Nearly all indexes would have a total length of deleted than 1 block meaning nearly all indexes need rebuilding. I don't think so ... h.. Your discussion on the clustering factor affecting the likelihood of requiring an index rebuild is still flawed, however interestingly, you've now given an example on why this is the case. However, you've still come to the wrong conclusion !! Firstly, you're incorrect in your example to say that a 1,000,000 row table with a clustering factor of 1,000,000 has it's rows in the same order as it's index although I guess this could be a typo. Regardless, if you delete all last_name beginning with a K, you are going to delete consecutive leaf nodes regardless of the clustering factor. So what difference does it make to the index. None. To the table, yes, you either delete rows from all differing blocks or rows from a small number of blocks but to the index, it makes no difference, hence your claim makes no
Re: Oracle Data Guard
Hi Vijay, I've done around 20 DG installations at different sites, using Linux, Solaris, AIX and W2K. High speed network isn't always what you need, low latency might be more important. I've set up a DG environment between Kuala Lumpur and Rotterdam, using a 128KB line. This wasn't for standby reasins, but was about database consolidation. As long as the daily Archive Log could be done, everything was OK. For maximum availability/protection mode you get synchronous writes. Latency counts very much. See also DocId 233650.1 on Metalink, Titled 9i Data Guard Complete Reference. It actually contains a list of interesting Data Guard publications on metalink. Force logging mode is required for Logical Standby. I agree with Tanel, LSB isn't for production yet. However, in some situations it might be usefull for a reporting database, as long as you do not rely on the standby part. Create a PSB for that purpose. On one site, with a long distance PSB ( 100 km between datacenters), with requirements about Zero Data Loss, I advised to setup a PSB/maximum availabilty mode locally, and a remote PSB in max. performance mode. This minimizes the chance of data loss, and affects performance as little as possible.

My guess is that Cary Millsap, Anjo Kolk, Steve Feuerstein and Howard Rogers know a thing or two about the Jurassic period in the database development. BTW, that was also when buffer hit ratio was invented. The entries that you see are remnants from oracle v6, together with the table called V$ROWCACHE and are both religiously maintained for the compatibility reasons, because Oracle Corp. doesn't want to disappoint all those who are still running V6. Even compatibility with V5 is still maintained. In Oracle 5.1.22, dictionary views weren't called user_tables and user_objects, they were called tab (user_tables) and cat (from CATALOG, replaced with USER_OBJECTS). The term CATALOG was directory command on Apple IIe (6502, later Z80) with 100k floppies, computer immensly popular at the time, and I believe that is why the first implementation of user_objects was called catalog. Now, let's fast forward to the present time and Oracle 9.2.0.4. Do Select * from tab and select * from cat. You'll be surprised.

Our 30-50% of our Production data needs to be replicated to another database and where they will have their processing and batches. It all depends on the amount of redolog you generate. When that's pretty much, you waste some resources by transporting online/archived redologs you actually don't need. Now We didn't go to Snapshot because It is on multiple tables (where we didnot have PK's and many tables) and due to performance issue I didn't want to use Snapshots (they did not want any tables to be truncate before being loaded even via snapshots). So, they don't like nologging operations like truncate, not even on the standby database? The best option I think is Logical Standby Database. Or Can you please suggest me any other means. Replication should be quicker like once in every 20 minutes, Even Transportable tablespacs does not work here since they need all tables to 24*7. LSB might work, but do not consider the option of failing over to it. Be aware that, altough in maximum protection mode your redolog arrives at the SB system within the transaction, it doesn't get applied there instantly. SQL Application takes place _after_ the log-switch on the Primary. When you take 10 minutes of redolog, and perform a logswitch, the SQL Apply process might even take longer than 10 minutes to complete processing of the redologfile. There is a risk that not every transaction arrives within 20 minutes at the LSB. So, your log-switching frequency and the amount of redo you generate per unit of time both play a major role in the refresh rate of the LSB.

Re: Oracle Data Guard
With TCP over standard ethernet the maximum transfer unit (MTU) is about 1500 bytes, this means if you want to send 2000 bytes over network, you have to fragment it in 2 packets and send them separately. This means double packet headers, double latency etc. Jumbo frames is a capability of some Gbit ethernet cards which allow them to transfer about 9000 bytes in a single packet. SDU is session level transfer unit (session data unit). When you enable jumbo frames and set MTU/SDU to 8192 for example, you'll fit much more in single packet, thus increasing performance for larger transactions. Also make sure that TCP.NODELAY is unset in your sqlnet.ora or is set to true.

The answer is it depends on your environment, your desired results, and, more often than not, your corporate structure. Here's some examples: 1) Monitoring script pages DBA group if X happens, Unix group if Y happens, Network group if Z happens. Simultaneously, XTerm windows are popped up in both Operations and HelpDesk with the name and pager number of the person paged (via uucp) 2) Monitoring script sends messages to centralized Error Management System. Error Management System handles it 3) Monitoring script finds problem and corrects problem. If problem continues, email is generated 4) Error Management System has external handles (not APIs) which can be used to call Monitoring Scripts, which need to be modified to ustilize System's internal structures (sometimes written in French -- *that* was fun!) 5) Monitoring script simply sends emails 6) Monitoring script keeps track of the errors in log files which are compared to log files from X time ago and only the differences are reported 7) Monitoring script has redundancy built in such that the first X times a particular problem is encountered, the Monitoring System ignores it, then generates a page 8) Monitoring script has redundnacy built in such that after the first time the problem is encountered, a page is sent, and if there is still a problem 15 minutes later, someone else is paged and so on up the company ladder It goes on and on. This is largely what I've been doing for the past 8 years. Note that the words Monitoring script as used above is generally an inherently complicated conglomeration of several different scripts, generally with a governor and/or one or more driver(s), infrequently on different operating systems, sometimes in multiple languages and/or utilizing, or integrating with, or extending the capabilities of, one or more COTS products, which use different mechanisms to trigger and synchronize them. Generally, there is some kind of IGNORE functionality which allows for specified downtime for maintenance, or ALTERNATE functionality for unusual yet definable situations, and hierarchy of tests (if the database is down, that implies that a subsequent error that a user cannot connect to it has already been dealt with) and, occasionally has sniffers on other boxes to determine whether remote scripts need to be run either dependent upon remote conditions or independent of them. Sometimes, there is a process which kicks off other jobs and manages the security. I particularly enjoy those where there is fault tolerance built in such that if Monitoring script X on Machine Y craps out, Machine Z takes over and runs the scripts until Y is back, then copies the logs back, kicks off Y, make

My guess is that Cary Millsap, Anjo Kolk, Steve Feuerstein and Howard Rogers know a thing or two about the Jurassic period in the database development. BTW, that was also when buffer hit ratio was invented. The entries that you see are remnants from oracle v6, together with the table called "V$ROWCACHE" and are both religiously maintained for the compatibility reasons, because Oracle Corp. doesn't want to disappoint all those who are still running V6. Even compatibility with V5 is still maintained. In Oracle 5.1.22, dictionary views weren't called "user_tables" and "user_objects", they were called "tab" (user_tables) and cat (from "CATALOG", replaced with "USER_OBJECTS"). The term "CATALOG" was directory command on Apple IIe (6502, later Z80) with 100k floppies, computer immensly popular at the time, and I believe that is why the first implementation of "user_objects" was called "catalog". Now, let's fast forward to the present time and Oracle 9.2.0.4. Do "Select * from tab" and "select * from cat". You'll be surprised. For all those still running V5.1.22 with forms 2.0 and 2.3, the world is not over yet.

I notice that "Pct Get Miss" for dc_used_extents ,dc_free_extents and dc_histogram_defs are high (the second column data below). Is this something I need to pay attention in terms of doing performance optimization? If yes, what are the things (regarding "Dictionary Cache") that I should look in order to improve the performance? TIA.

Re: Add/Drop partition and CBO statistics
Hi list: I did another add partition last monday evening, and that time everything is ok. Maybe statistics did not change much(like high value in tables/indexes). I will do more research and give feedback to you . And I think there must be other DBAs also using partitions, why not share your pains and gains? Regards. Zhu Chao. - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thursday, December 04, 2003 4:49 AM I've got a perfect application for partitioning by date. Each month is a new batch of data and everything is set for the last date of the month. But they asked me today, if we drop a partition of old data, and then add a new partition for the next month, load it, what needs analyzed? Is it enough to simply analyze the new partition? -- 13308 Thornridge Ct Midlothian, VA 23112 804-744-1545 Reply in lines. Zhu Chao - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Wednesday, December 03, 2003 7:29 PM Agreed that scanning one big index is faster than many partitions. Then raises the questions - I thought partitioning is for: 1) ease of archiving/dropping off old partitions - drop old and create new partitions in a sliding window. A single large global index negates a lot of this ease - even though it is true that deletes on non-partitioned tables would be even more inconvenient. Yes, that is why we use local index.not Global indexes. 2) efficiencies in partition pruning for queries. If you are querying whole table - why bother with partitioning? The point then becomes you don't need to partition in the first place, or your partitioning scheme is not appropriate? Sometimes it is constrained by complex real applications. A table has tens of columns and you can only partition by one key(or several columns), and to use partition elimination, the SQL must contains the partition key. So only these limited SQL can use partition pruning. While in complex real life application, there will always SQL with different where clause that do not use the partition key at all. The other constraint is business logic.We should partition according to product online time, but we have ten tables to archive and only one table(products) has that key, all other tables do not have that column. Adding such a column to other tables need considrable application rewrite and is denied. So we use product_id(the primary key of most tables) as the partition key. When partitioning key is not a part of the index and you are querying whole table, then it is faster to scan one big index than many smaller ones. The difference is something like log rows to partcount*log (rows/partcount). BTW, local indexes are the only way to go -- I've never understood the point of global indexes on partitioned tables -- maybe someone else can? Global indexes are faster than local index, so if you have schedule down time and need better performance, go to global index. OLTP is more suitable for GLobal index, tomas kyte said in his expert one on one. Regards Zhu Chao.
