RE: password question
But where do you get the "known" or "captured" hash ? Only a DBA can query DBA_USERS for PASSWORD. A regular user cannot query DBA_USERS and cannot see PASSWORD in ALL_USERS. If you are already a DBA on the target database you really don't need to find out the password for another user. Supposing you grab a site's FULL Export dump. I guess you can then do a FULL Import and get the "captured" hash. But why do you need it now that you have the FULL Database with you anyway ?

Oracle8i - Oracle9i issue??????
Title: Oracle8i - Oracle9i issue?? Hello Guru's I wonder if any of you have had this problem, we have a external company developing a software package in C#. On their Oracle9i test system, the software works fine, however once brought accross to our systems, which is an Oracle8i ( 817) system the software gives a (ORA - 00933 SQL command not properly ended) error, but funny enough only on the one window. I am told by them that they do straight select from a table, saving the returned columns in variables etc. The only difference is they don't have any semi-colons (;) at the end of the their queries. But catch 22 it works on the other screens(windows). Hope you folks can help TIA Denham This e-mail message has been scanned for Viruses and Content and cleared by MailMarshal - For more information please visit www.marshalsoftware.com

Hi, All, Is there any Oracle data dict view to see whether the dbms jobs is on the job queue or not. Why I ask this is that I use dbms_job.remove to remove one job, later on, I check it using user_jobs, it's still there. Thus issue dbms_job.remove again, this time, this execution seems hung there. I log into sys and issue dbms_job.remove, I got the following error ORA-23421: job number 41 is not a job in the job queue ORA-06512: at "SYS.DBMS_SYS_ERROR", line 86 ORA-06512: at "SYS.DBMS_IJOB", line 525 ORA-06512: at "SYS.DBMS_JOB", line 166 ORA-06512: at line 2 Could anyone tell me why this happens? or is there any dict view to check the job queue?

Re: sql question
Rich, Are you sure that that is what you want ? Suppose your range values were something like : begin end 1 9 1519 2329 ie, the RANGE table shows that 10-14 and 20-22 are invalid ("not allowed") values. Your problem statement and the SQL that Paul provides for the problem statement would return numbers like 10, 11, 20,21 which are, actually, invalid. You'd have to write a cursor to loop through the valid ranges ??

Re: password question
Sameer, The obvious answer "you can't decrypt the password". Else a number of people would think harder about buying Oracle. It's a one-way hash -- you can't get the original value back. It is possible to temporarily reset a user's password to something else, become the user with your own password and reset the password back to the original value, without knowing what the original password was. e.g. suppose a user's encrypted password string is 'ABCDEFGHIJKLMNOP', read this string from DBA_USERS, store it someplace (a variable, a table ;>), execute ALTER USER identified by , login as the user CONNECT /, do your SQLs as that user, reset the user's password ALTER USER identified by values 'ABCDEFGHIJKLMNOP' Hemant K Chitale Principal DBA Chartered Semiconductor Manufacturing Ltd "Ghadge,Sameer" <[EMAIL PROTECTED]> 22/02/2002 11:38 AM Sent by: [EMAIL PROTECTED] Please respond to ORACLE-L To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> cc: (bcc: CHITALE Hemant Krishnarao/IT/CHRT/ST Group) Subject: password question Hi, Oracle stores password in encrypted format, is it possible (suppose i have access to dba_users table) to retrieve and descrypt the password. thx Sameer -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Ghadge,Sameer INET: [EMAIL PROTECTED] Fat City Network Services-- (858) 538-5051 FAX: (858) 538-5051 San Diego, California-- Public Internet access / Mailing Lists 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).

RE: Problem with standby database & listener
Could it be that the standby is auto-registering itself with the listener for the production database? We've had a couple of incidents where a development DBA copied the init.ora file from a production database configured for MTS. But the listener parameters were not changed and all new connections were redirected to the development database. I suspect that the standby is auto-registering itself with the listener and bumping of production. Bouncing the production server then does it back to the standby. HTH Tony Aponte -Original Message-From: Stephen Andert [mailto:[EMAIL PROTECTED]]Sent: Thursday, February 21, 2002 3:59 PMTo: Multiple recipients of list ORACLE-LSubject: Problem with standby database & listener Fellow dba's, We have come across a weird problem with a standby database. Every time we issue "alter database mount standby database" on the standby database, the primary database fails to connect through listener. It becomes OK after primary database is shutdown and restarted of course this can is not an acceptable solution since the standby will be opened every week for reporting. Anyone experience this before? Any direction would be appreciated. Thanks Stephen AndertScottsdale, Arizona

Re: How to make deletes faster.
How'bout 1) add a char(1) column...call it DELETE_ME and allow NULLS 2) index the DELETE_ME column 3) every night run an update like UPDATE yourbigwhackintable SET DELETE_ME = 'Y' WHERE the row satisfies your delete condition 4) DELETE FROM yourbigwhackintable WHERE DELETE_ME = 'Y' This is assuming of course you have free reign over the app as far as adding a column and the index. The index won't store the NULLs of the non-deleteable rows if you were worrying about index size BTW. Note..this technique is not 'mine'...I got it from a book (can't remember which one!) so your mileage may vary!

In creating the new control file for test (which we had to do to rename the database and rename the datafiles), we failed to include in the datafile list one of the newly added datafiles in production (we used an old create statement, forgetting that the production layout had changed). (The datafile name was 1 of 5 datafiles which make up a user tablespace). The controlfile create command succeeded and we were none the wiser. UNTIL... We started to get errors a few days later when trying to insert into a table which resides in the tablespace. We got errors to the fact of 'datafile 306 does not exist, cannot insert. At that point, oracle decided to put a stub in the datafile system tables for our missing datafile. So now we have the dreaded '/TST/oradata/MISSING00306' entry. 2) I ran a query against the dba_extents table to find the objects which have data in the missing datafile. There were three tables. I know the proper recovery method is to restore the datafile and recover archive logs. We cannot do this for two reasons. The first is the fact that this is a cloned database and was opened with resetlogs. The second is the fact that the datafile was never in the controlfile create statement. Thus it's header information still points to the production database name, while all the other datafiles now have the new test database name in their header information. Oracle will not let you add it now to the existing datafiles. Nor will it let you recreate the controlfile with the filename included. All datafile headers must contain the same database name when creating the controlfile. The next suggestion would be to reclone. We cannot do that either as we've already performed too much work in the test instance to trash it. 3) So, I decided to drop the objects which were referenced in the missing datafile and recreate them. That way the objects will be built in a good tablespace and the users can insert into them. This worked, sort of. The drop seemed to succeed, even though it produced the errors above and dropped my connection. But I was able to log back in and successfully recreate the objects. I assumed oracle was trying to update the freelists header in the datafile and bombed when it could not find the datafile. It did remove the table names from the segment information, as I was able to create new tables with the same names. 4) Ok, so now I have good tables and the users are working fine. So what's the problem? Well, I queried the extents view again to see if anything was still pointing the missing datafile. yes. It seems oracle modified my old tables (pre-rebuilt) to temporary segments! I now have the same extent usage and # extents for 3 temporary segments in the same locations. That's ok, because I can still use my new tables without problems. The problem is SMON. SMON is trying to coalesce/drop temporary segments and spewing the; ORA-0: Message not found; product=RDBMS; facility=ORA error every 10 seconds! Is there any way to drop these temporary segments? Any way to drop the references to the missing datafiles? I have already done a 'alter datafile offline drop;' and it succeeded, but smon is still getting errors. How do I shut SMON up? How do I get rid of these temporary segments (which have data in a missing datafile)? I've bounced the instance also. I believe my only recourse now is to drop the tablespace which contained the missing datafile, which should remove all references to the datafile, correct? I don't even know if that's possible as it's over 20gb and I have no way to move all the objects out it (contains Apps tables and lobs and such). Anyone have any bright ideas or is our instance hopelessly confused? __ Glenn Travis Database Administrator Business Intelligence & Support [EMAIL PROTECTED] 919-531-0434 -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Glenn Travis INET: [EMAIL PROTECTED] Fat City Network Services-- (858) 538-5051 FAX: (858) 538-5051 San Diego, California-- Public Internet access / Mailing Lists 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).

RE: RMAN Question
Ashoke If I understand you correctly, you are using RMAN to backup to disk, rather than to a media manager. You are asking whether you can archive these in RMAN, plus leave them on disk so they are readily available for recovery. I have used this configuration, and I have found that RMAN leaves the archive logs on disk after it has backed them up. Also, I believe but have not tested this, that in case of a recovery, RMAN first looks to the original unarchived disk location for the archive logs and if it can't find them there, it will retrieve them from its backup location (disk file or tape if you are using a media manager), and put them where they should be, then continue the recovery. After thinking about this, I decided that using RMAN to backup the archive logs wasn't buying me anything. Just making my setup more complicated. If I was backing up to a media manager, then having RMAN back up the archive logs would be great because it would be moving them to tape. As it is, RMAN isn't compressing them before moving them to disk. My regular nightly tape backup will give me a safety copy on tape. If I feel I need a disk copy, I will just compress the files to another location and end up with something significantly smaller. If I have overlooked something in my logic, please point that out to me because I am just beginning to learn RMAN and am frequently interrupted by other DBA duties, so learning is going very slowly.

RE: Problem with standby database & listener
I have 8.1.7.0 on Solaris 8 and also had this problem. Somehow the way I get around this is to go back to the Primary db and reset the log_archive_dest_2 to whatever the identifier of the standby db is. (even if the log_archive_dest_2 is already set). Then I do the standby recovery, then managed recovery. This probably explains why yours work after you bounce your Primary db. You must have the standby db location set in the init.ora file. What I do, however, is force a reset of the standby db location after I startup the standby db. This way I don't have to bounce my Primary db. Everything's scripted. Clear as mud? HTH.

Using views makes for easy report/SQL creation, but tends to be a tuning and performance nightmare. It's hard to tune, and will likely never perform well. I'm going through similar issues here right now. A number of users need to do reporting on production data. No way, no how will they be allowed to do it on the production database. It's a manufacturing database and performance is critical to this system. I've done some prototypes of the tables they need to report on. Basically a copy of the production tables in another database. Those that have a long refresh cycle ( 1+ days ) get bitmap indexes on most columns. Those that need to be close to realtime get Btree indexes instead and will be refreshed every few minutes ( refresh time pending negotiation with users :). This is not exactly a data mart as I would like to have it: no star schemas. But it's what I have time for right now, gets the reports off of production and is *much* faster to query.

Re:ROWID datatype columns and primary keys
Patrice, ROWID access to data is the fastest way to get from here to there since it, the rowid, tells Oracle right where the data is. The biggest problem that I see with rowid's is that 1) they changed from Oracle 7 to 8 & most likely will change again in the future, 2) when you re-org the table they change, and 3) people sometimes like to manipulate the rowid's which can have some very strange results. My favorite use or rowid's is to simulate a "for update of" cursor when I need to do a commit and/or rollback in the middle of the cursor. I've also used them when I want to delete a specific row of data and don't have any other unique way to id it. I do not, and very strongly do not, recommend manipulating rowid's for any reason, period. Extract them from the database and use them as provided.

RE: Instance Monitoring Tools
StatsPack, V$SYSSTAT, V$SYSTEM_EVENT, V$SESSION_EVENT, V$SESSION_WAIT, trace files, and a good DBA... only the last item is not free. Take the money you save on tools and give it to the DBA. Sorry if this sounds flippant but is there anything which the tools provide via a GUI interface that isn't already available via the data dictionary, Oracle utilities and packages, and O/S utilities? In fact, most of the tools get their data from the same aforementioned sources. I've also gotten monitoring information from Oracle's supplied MIB's via SNMP just like OEM does but I used the pathologically eclectic rubbish lister tool. :-) Tools are not a substitute... if I give you a hammer it doesn't make you a master carpenter. I guess it's a matter of preference. I like making my own tools, or "borrowing" scripts from others and adding them to my toolbox. Of course the commercial tools are more complete than my grab bag of stuff which is under perpetual development and I sometimes spend a lot of time trying to find a script amid the chaos of the unkempt toolbox. ;-) I know there one of those whatchamagizmos in there now where is it?

RE: Anybody against using views?
Well, I am dinging views in the sense that they are easily abused for reporting purposes. Recreating the data on another server lets me create indexes that I wouldn't want to create on the production server, and indexes that I can't create in production, such as bitmap indexes. The queries will be faster, and more importantly, they won't be hitting production.

Re: ROWID datatype columns and primary keys
ROWID's have their place. My preference is that they are used in PL/SQL or other code as a means of quickly locating or relocating a row in a table. Using them procedurally at runtime is generally considered a valid use of ROWID data types. Storing ROWID data is generally considered a bad practice for the reasons you mention.

Re: ROWID datatype columns and primary keys
I am sure someone has a reason for creating a column with a ROWID datatype but I cannot think of it. Every row has a ROWID column anyway so why create another one. That column would have to be kept update on almost any kind of DDL performed on that table. I cannot imagine populating that field with any other value than actual ROWID which you already have.

RE: ROWID datatype columns and primary keys
Oracle changed the ROWID size between Oracle7 and Oracle8. It went from 6 bytes to 10 bytes. So if a developer wrote code that only sized the ROWID to 6 bytes, it's probably not going to work when converted to Oracle8 or 9. Jerry Whittle ACIFICS DBA NCI Information Systems Inc.

RE: ROWID datatype columns and primary keys
In my previous job, ROWIDs were used left-and-right for performance benefits (accessing a row using ROWIDs is the fastest)and were integral part of the Appl Design at that time. Other than performance, I do not know why one would want to use it. However, it prevented us (Tech Support, SDBA) from table reorgs via export/import. So, we eventually faced performance problems due to other issues. Later, the Appl was redesigned for newer versions of oracle without relying on the ROWIDs.. - Kirti -Original Message- Sent: Thursday, February 21, 2002 12:18 PM To: Multiple recipients of list ORACLE-L Can someone explain to me why some developers like to create ROWID datatype columns in their tables?

RE: Anybody against using views?
Hello Ron I do not know this package because we use another reporter (business Objects). If it is like our there are clear pro and con for using views: Pro: you CONTROL the access to oracle. Con: YOU control the access to oracle. The pro means that you write the selects and can tune them and optimize the access to the DB. The con means that you do a lot of work for them and you will maintain the views each time there are changes. Instead of setting up the connections between tables in the application, you will set it up in views and the developer will simply do select on the view.

Re:RE: Anybody against using views?
Bambi, There are times when I really don't like people using a view to do complex queries. I'll give you an example of one PIG I have, although I'll re-write it to just provide the idea of what they did. The original definition is claimed by the vendor as "proprietary". Anyway, here is the basics of what their doing: create view oops as select a.name, b.dept, c.value from (select name, empid, deptid from emp group by name, empid, deptid) a, (select deptid, dept_name from dept group by deptid, dept_name) b, (select empid, sum(value)value from sales group by empid) c where a.empid = c.empid and a.deptid = b.deptid group by a.name, b.dept, c.value; Got any idea what this does to the database? Of course I forgot to mention that each of thise dynamic tables has a corolated subquery + other stuff built in as well. The vendor claims that this runs very well in their test database, which it does (total space = 128Kbytes of disk, the tables have < 10 rows each). Problem is that in our production database which has 1.5GB of disk space (1 row in test = 50 rows in production or more) in active use it runs really badly. Dick Goulet Reply Separator Author: "Bellows; Bambi" <[EMAIL PROTECTED]> Date: 2/21/2002 9:38 AM If you're using views properly, they're wonderful and allow a phenomenal amount of flexibility to the designer, but like all powerful beings, they must use their power for good (complex query manipulation) rather than evil (resource hogging).

RE: Anybody against using views?
One of the mains reasons we used views at one place I worked was the "table drop" factor. We never created a table that we didn't immediately create a "select * from ..." view on. We then granted the privileges on the views instead of the tables so that if we ever had to drop and recreate the table all of our grants would stay intact on the view. Now that you can rebuild the table without dropping it I don't think this approach has much merit but it is something to consider in older databases. Just one more point of view :) --Michael -Original Message- Sent: Thursday, February 21, 2002 12:29 PM To: Multiple recipients of list ORACLE-L I like views... right now I'm working on the one out my office window... a spectacular view of the Tobacco Root range across the Gallatin Valley. :-) Regarding database views, you can't say they're entirely good or bad.

RE: Anybody against using views?
Trouble with some views is, with certain front ends (Business Objects likes this particularly well) the only way to get it to accept the queries is to create MULTIPLE views on the same table and do recursive "self" joins that way. It makes for very untidy SQL that is practically un-tune-able. I would say that to use or not to use is very subjective and situational. I would use views in Jerome's situation, but Synonyms are better in others... and redesign beats both in a lot. -Original Message- Sent: Thursday, February 21, 2002 11:04 AM To: Multiple recipients of list ORACLE-L Just yesterday a developer was having a performance problem with a complicated report was taking about 7 minutes to complete.

RE: Anybody against using views?
I like views... right now I'm working on the one out my office window... a spectacular view of the Tobacco Root range across the Gallatin Valley. :-) Regarding database views, you can't say they're entirely good or bad. They may simplify things for reporting but they could complicate your ability to tune the SQL... it just depends. Ad hoc end user queries on a separate non-OLTP reporting server is one thing, ad hoc end user reporting or batch reports with views of production source data on an OLTP server is could be quite another. The idea of having business object views of data and turning end users loose with a reporting tool without DBA supervision can be both appealing and frightening. But duhvelopers SHOULD know what they're doing. ;-) Looking out the window in Bozeman, Montana...

Re: Anybody against using views?
IMO views are often used as a substitute for creating reporting structures. Using views makes for easy report/SQL creation, but tends to be a tuning and performance nightmare. It's hard to tune, and will likely never perform well. I'm going through similar issues here right now. A number of users need to do reporting on production data. No way, no how will they be allowed to do it on the production database. It's a manufacturing database and performance is critical to this system. I've done some prototypes of the tables they need to report on. Basically a copy of the production tables in another database. Those that have a long refresh cycle ( 1+ days ) get bitmap indexes on most columns. Those that need to be close to realtime get Btree indexes instead and will be refreshed every few minutes ( refresh time pending negotiation with users :). This is not exactly a data mart as I would like to have it: no star schemas. But it's what I have time for right now, gets the reports off of production and is *much* faster to query.

Re:Anybody against using views?
Ron, Kind of depends on what the view is being used for. I've several examples of views that are real PIGS with regards to cpu and temp space usage (Sorry, I can't share them as they belong to a third party application). I've also eliminated a few of these PIGS, these I could share, by some other database trickery. My favorite reason NOT to use views is when the view does some data manipulation based on some strange criteria (been forced into a couple of those & boy do they create confusion). I'm also not too fond of views whose sole purpose in life is to rename a column or two from the original table. Otherwise, to perform common joins and the like, their great.

Re:RE: Options instead of ODBC + MS-Access [Slightly? Off-to
Sean, We too have used Access in the past and still do today. Dennis does bring up some very good points & your developer sounds very competent since he/she is bringing this up vs. trying to gloss over the problem. Our major salability and consistency problem with Access were and remain two fold. 1) the OBDC driver being used. Some of the MicroSoft drivers for Oracle have this nasty habit of never closing connections. It is not hard to find your process limit being hit. The option here is to use MTS but the better solution is to get everybody to use a decent driver. I can look up the one we use if it will help. 2) People storing data from Oracle into Access. This one is a real pain in the (I won't go there). What happen to us in this arena is that the developer attached to the Oracle tables and simply scanned them into local Access tables, then did whatever data processing he wanted. Worked rather well while the data volume was low, but as it picked up the application slowed dramatically & I never heard the end of the "slow database" complaints. Thankfully our network admin could prove to the developer that the problem was local. The other problem was that once the Oracle table was scanned the application continued to use the same data until it was shut down. Made the reports look a little funny as the day progressed.

RE: A question for people who also know Sybase
Title: RE: A question for people who also know Sybase Melissa, Finally made it work last evening. The interfaces file (like our tnsnames.ora) that is used by the Sybase client to connect to servers has 2 different formats that can be used: TLI and non-TLI. Was using TLI format for all servers. When I used a non-TLI format to these 2 servers, the connection went thru and the gateway started working. So I guess this is some kind of setup issue with the Sybase server. If any of you have questions to configure Oracle Transparent Gateway with Sybase, I will be glad to help. The documentation is not really helpful.

Have converted the IP addresses and the port numbers to Hexadecimal and have made the necessary changes to the 'interfaces' file on our Unix box. We are able to successfully connect to 5 databases and retrieve data using isql. But we get the following error for the remaining 2 sites when I issue the isql command: CT-LIBRARY error: ct_connect(): network packet layer: internal net library error: Net-Lib protocol driver call to connect two endpoints failed We are able to ping these 2 servers and also do the 'traceroute' successfully. Also, I am able to connect to these 2 locations using the Sybase client on my workstation. This verifies that the IP address, port#, user-id and password are correct. Just the connection through Unix fails and have to make this work so that our Oracle database can talk to Sybase using the Oracle Gateway. Oracle Gateway is able to retrieve data from the remaining 5 Sybase servers. TIA! Prakash --

RE: Options instead of ODBC + MS-Access [Slightly? Off-topic]
Sean - I think that Access tends to be a wonderfully cheap and easy Oracle front-end for exactly the situation you described. Naturally, if your site has standardized on a different tool, then it isn't good, or if the staff is highly competent in another tool. I think the developer's concern is an excellent opportunity for you to introduce the subject of scalability. Think about it. The scalability problem in this situation isn't in Access, but in the Oracle data model and in the SQL statements that Access issues (okay technically that part is in Access). If the data model is well-designed and the SQL statements aren't doing something like full-table scans, then it should scale well. Okay, the other gotcha might be if the size of the data you are extracting from Oracle will eventually overwhelm Access. If someone else on the list knows any other Access points of concern, perhaps they will share them. Dennis Williams DBA Lifetouch, Inc.

Re: Rollback Segments
Bambi, HLI and OCI - that reminds me of another nice one from the dark ages. Some of you around here, who consider yourself "old" in terms of Oracle may remember, the oci call osql3(), which was later superceeded by oparse() (version 6/7-ish, I think). Well, the reason for the old call being called osql3() was that it was new with version 3! In version two, osql() was found, but it was limited to 6000 bytes of SQL statement text, where osql3() made it possible to go to to 64k. Rgds, Bjørn.
