Rollback segments size calculation
Hi all I am getting ORA-01555 in my database and the solution is to create huge rollback segments but my doubt is how to calculate the size of this huge rollback segments . Now I have 24 G of space in rollback segment tablespace .But still i am getting the error.The environment is datawarehouse and loading happens almost every time except at night . and while loading data loading updataion and deletion happens frequently .Please help me in calculating the size of huge rollback segment .

If you are now running in manual undo mode and have created rollback segments, you can remove the undo segments. Verify that the segments are offline and you are not using them.

Undo Tablespace vs Rollback segments
Can anyone point me to an article or white paper that goes into detail on this. When I RTFM, it just says use Undo TBS, don't worrry about it and all your problems will be solved. We are upgrading from Oracle8 to 9i and currently have Rollback segments in 4 tablespaces spread over 4 disks. It looks like you can specify multiple data files, but I can't find anything on how they would be used. I know that striping would spread the load, but that is not an option.

Steve, You may have to dig a little further... What happened to those table(s) in that schema prior to starting the export? Heavy DML, may be? This could be a case of 'delayed block cleanout'.

RE: exp, dbms_stats, RMAN and rollback segments
Hi Kirti, Sounds like you have the same suspicions as do we. So far as we know there isn't any heavy duty DML before the export and there isn't any other activity on the schema other than RMAN and DBMS_STATS. We don't understand how RMAN or DBMS_STATS ***could*** be the culprit but we've seen WEIRDNESS before. We host our webapp and upgrades are customer driven. (Shivers and shudders!) Upgrades often entail database changes so the application shuts out end user access and kicks off an export before changing tables, munging data, updating the code, etc. This process has been fairly automagic and the export went along about 5 minutes before it crapped out. The only known difference between this upgrade run and other successful ones is that dbms_stats was running. So now I've copied the data into our test environment in an effort to duplicate the error and walk through our code. Luckily it's not written in Perl so it won't be too hard to read. :-) Also, Walt found some delayed block cleanout issues on Metalink associated with analyzing indexes. The DBMS_STATS.GATHER_TABLE_STATS(...) routine in question is using the cascade option so I'm beginning to smell smoke. There are a few docs on Metalink about how ORA-01555's can occur even when NO updates are being performed but statistics are being gathered. WEIRDNESS!! See DocID's 367016.995; 17730.996; 45895.1; 89633.996; 61552.1. UNFORTUNATELY... the solutions proposed are not very appealing. Meanwhile we're trying to convince others that Oracle is better than MySQL even though MySQL continuously updates its optimizer statistics and doesn't have problems like this. :-( And proposing a blockout period when customers are not allowed to upgrade while maintenance operations are going on would not be very well received. Especially since it's not an issue with MySQL and how we keep talking about how Oracle is a better 24X7 solution for our 24X7 webapp. Arghh! Big sigh while contemplating a lot of tedious work and getting nowhere... And I had to get up at 2:30 A.M. this morning to help fix the outage. Whine, whine, whine...

RE: exp, dbms_stats, RMAN and rollback segments
When one runs dbms_stats how often is the data committed? Before Oracle exports a table it needs to gather information about it such as the columns comprising it. I wonder if this information also includes data changed by dbms_stats and/or RMAN. We used to have similar problems when exporting while an application was doing quite a few drop tables and CTAS's. However that pretty much went away with 8.1.7.

RE: Rollback Segments on 8.1.7.4
I will have to check your question on 'fewer sorts'. As far as changes to the SQL statements, there were 1 or 2 sql statements changed in the application because they no longer worked efficiently with the change to 8.1.7. But, on the whole (lets say 98%+ of the time) no changes were made. -Original Message- Sent: Monday, March 10, 2003 5:39 PM To: Multiple recipients of list ORACLE-L Did any of the rollback segment storage parameters (i.e. INITIAL, NEXT, PCTINCREASE, MINEXTENTS, MAXEXTENTS, OPTIMAL) or the number of rollback segments change between 8.0.5 and 8.1.7? Changes to any of these variables could impact the space available for storing inactive undo blocks for read-consistency purposes. If the answer is of course not, then here comes the harder question: did the SQL statements change between 8.0.5 and 8.1.7? Not just outright different SQL statements, but even the same SQL statements running with different execution plans? For example, changing explain plans so that SORT-MERGE join is no longer use could have significant impact on ORA-01555, as forcing sorts are one way to minimize SNAPSHOT TOO OLD. Having queries run faster is another way to minimize ORA-01555, so getting rid of SORT-MERGE joins will likely help, but if the performance improvements aren't good enough, then the conversion to HASH or NESTED LOOP joins may allow more ORA-01555 to occur. Have you noticed fewer sorts occurring since 8.0.5?

Re: Rollback Segments on 8.1.7.4
Did any of the rollback segment storage parameters (i.e. INITIAL, NEXT, PCTINCREASE, MINEXTENTS, MAXEXTENTS, OPTIMAL) or the number of rollback segments change between 8.0.5 and 8.1.7? Changes to any of these variables could impact the space available for storing inactive undo blocks for read-consistency purposes. If the answer is of course not, then here comes the harder question: did the SQL statements change between 8.0.5 and 8.1.7? Not just outright different SQL statements, but even the same SQL statements running with different execution plans? For example, changing explain plans so that SORT-MERGE join is no longer use could have significant impact on ORA-01555, as forcing sorts are one way to minimize SNAPSHOT TOO OLD. Having queries run faster is another way to minimize ORA-01555, so getting rid of SORT-MERGE joins will likely help, but if the performance improvements aren't good enough, then the conversion to HASH or NESTED LOOP joins may allow more ORA-01555 to occur. Have you noticed fewer sorts occurring since 8.0.5? Just some ideas... - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Monday, March 10, 2003 2:59 PM Evening; Has anyone noticed any difference on the way Oracle uses Rollback Segments on 8.1.7.4 versus 8.0.5 ??

import and rollback segments

I got a live system with many smallish segments, the dump file is about 20 GB and take just over 12 hours to process but it requires a big rollback segment.

Re: import and rollback segments
If you cannot take the small ones offline, I do not think you can force to use a particular RBS. You could possible create multiple large RBS then take smaller ones offline then import. After completion put smaller ones online. You can try commit=y to commit after each buffer instead of each object. Use a larger BUFFER size on import to reduce round trips to export file.

Re: Increase size of data files and rollback segments
From bitter experience: Do not allow your datafile to autoextend across 4GB boundary. There is a bug that cause this datafile to be unusable. We had an all night session after this bug hit us. We had to call Oracle to come with the DUL utility to recover the data. Now we define our datafiles to be 1900MB each. Also each tablespace has an extra datafile with 200MB size with autoextend up to 1900MB. Our checks check that each tablespace has datafile with 200MB size. If not we get an alert and check the situation.

I think the 4Gb limit is confined to a handfull of older operating system versions or older Oracle versions.

It would require 2760 datafiles! Can anyone confirm that this is no longer a problem after certain versions of O/S and Oracle? Note another mean bug (8.1.6.2 / HP-UX 64-bit) where Oracle lets you specify no size for a datafile, then adds it to the controlfile /data dictionary in a way that makes it look like it has a ton (like a terabyte) of free space. The datafile can't be resized or offline dropped, and the tablespace must be dropped and recreated (unless you get the patch).

Re: Increase size of data files and rollback segments
Hello Jeremiah I did some research on metalink and it says: 1) Do not use datafiles more then 4GB on NT systems. 2) There is a bug on NT, W2K that if you resize datafile (direct command or autoextend) to 4GB boundary, i.e 4,8,12, then there are two conditions: 2.1) No archive log - database crashes but you can start again and resize the datafiles. 2.2) Archive log - restore and regenerate to a point in time prior before the resize. This bug was reported also on 9.2. The work around is to resize to 4.1, 8.1 GB datafiles. Bug number 1668488.

RE: Increase size of data files and rollback segments
Yechiel, Thanks for pointing out the potential issues with autoextending onto an exact 4 Gb boundary (as I forgot to include them). Reading the bug you referenced (at http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=BUGp_id=1668488) it says: ... Does not reproduce on 8.1.7 Sun Solaris. ... Rediscovery Information: Resize a datafile file to [exactly] 4GB, 8G, 12G, 16G, etc. After resizing a datafile to 4G, alter system checkpoint was failing with ORA-27069 ... This fix is in 8.1.7.4.1 and 9.0.1.4.0 but not in 9.2.0.2.1 I am on 8.1.7.4.5 and so am not affected by this issue - I can't remember the version the original poster was on. Anyone using 817x may also want to check note 120607.1 (http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOTp_id=120607.1) titled Support Status and Alerts for Oracle8i Release 3 (8.1.7.X) for information on this and other issues. This refers you to Note 148894.1 (http://metalink.oracle.com/metalink/plsql/showdoc?db=Notid=148894.1) titled ALERT: Problems with Datafile AUTOEXTEND/RESIZE on Oracle8i on NT/2000 Platforms This contains the information ... A fix is now available in 8.1.7.1.4 Bug.1823173 and will be included in8.1.7.3 BUG.1794199 ... For general Oracle information on 2Gb files see http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_id=62427.1p_database_id=NOT titled 2Gb or not 2Gb - File limits in Oracle.

RE: Increase size of data files and rollback segments
David, Wrong. we very much welcome Jeremiah here. He has helped countless people on this list, and if he on occasion chooses to make a joke (as do we all), then so be it. He was a good deal gentler and nicer than my first thought, which was to tell you to read the fine manual before asking basic questions. Many of us spend a LOT of time on this list, helping others. It is very discouraging though to continually get questions that can be answered by a very simple read of the manuals. I suggest that in the future, you attempt to investigate a problem yourself before asking a question. Besides the fact that you will learn much more by doing your own research, you will not annoy the members of the list who try to help.

Title: RE: Increase size of data files and rollback segments From: Nguyen, David M [mailto:[EMAIL PROTECTED]] Alright guys, just because you know Jeremiah better than me so you can take his joke. I have no idea who Jeremiah is from Adam, and I got the joke. Hell, I nearly flamed you myself, and I'm just a lowly developer. My apology to him as I did not recognize it was a joke, however when I am asking for help from the group, I am in a situation to resolve problem ASAP and hope to find a answer not a joke. The problem is that if enough people like you refuse to RTFM, then no one will want to answer questions because it'll be duller'n your resume. If you were in my situation, you would understand. I've been in your situation, and been damned ashamed of myself for not having researched the question first. It ain't all that hard...
RE: Increase size of data files and rollback segments
David, As a start, look up the following commands in the SQL Reference guide: alter database datafile 'C:\ORADATA\fred\DAT_LARGE_01.dbf' autoextend on maxsize 20480M; Read up on the implications of autoextend and whether you want it alter database datafile 'C:\ORADATA\fred\DAT_LARGE_01.dbf' resize 10240M; For rollback datafile - same as any other datafile, eg: alter database datafile 'C:\ORADATA\fred\ROLLBACK1.DBF' autoextend on maxsize 10240M; You may then need to add another rollback segment or increase the max extents of an existing one. eg to add another rollback segment: CREATE PUBLIC ROLLBACK SEGMENT r09_big TABLESPACE rollback STORAGE ( minextents 20 INITIAL 10M NEXT 10M MAXEXTENTS UNLIMITED) (you would then need to bring this online - eg alter rollback segment r09_big online;) For tempfile (ie LMT temporary tablespaces): alter database tempfile 'C:\ORADATA\fred\TEMP1.dbf' autoextend on maxsize 10240M; Remember - don't use the exact sizes I've shown - alter to suit your case (these were part of a huge load into a new test system) Hope this helps (and willing to learn if some of the above could be improved).

Re: How are rollback segments assigned?
Thanks Jared, thats not what I see. I have 20 rollback segments, and at no point in time, there were more than 4 transactions in the rollback segments. In fact, I happened to see it a couple of minutes ago. select usn, xacts from v$rollstat showed me 0 in 19 rollback segments, and 2 in one of them. And I have got alerts in place to alert me when there are more than 4 transactions in all of the rollback segments. And yeah, the rollback segments are online. Remains a mystery to me.

RE: How are rollback segments assigned?
Exactly. A guy might have to poll V$ROLLSTAT 100+ times per second to see the allocations happening on a system with well-designed transactions. You just can't do that with SQL. Raj, you *can* test the behavior by using some artificially *bad* transactions. On a quiescent system (nothing else running) with n rollback segments, open n+1 sqlplus sessions. In each session, update a row but don't commit. After each session's update, look at V$ROLLSTAT. To the best of my knowledge, the assignment algorithm has always been to assign a new txn to the segment with the smallest number of active txns in it. There are of course lots of ties (e.g., lots of segments might have 0 active txns in them). The tie-breaker in v6 was to assign in round-robin order (as the segments are listed in the init.ora file). In v7, the tie-breaker algorithm apparently changed to choose the segment that is listed earliest in the init.ora file. I don't know whether it changed again in 8 or 9. You'll know if you do the test.

Re: How are rollback segments assigned?
Here's one scenario: 4 transactions, 2 rollback segs tx 1 - rbs1 tx 2 - rbs 2 tx 3 - rbs 1 tx 4 - rbs 2 tx1 and tx3 finish. tx2 and tx4 have not yet committed.

Hello Friends, Oracle Parallel Server 8.0.6.2.0 on Solaris 2.6 Nodes We were having some locking and rollback issues, and I set up some scripts to alert me in case there are more than 4 transactions in the rollback segments, and more than 1 in any of the rollback segments.

Unsetting OPTIMAL in rollback segments
We are getting the following error in our alert log for a database where we are doing some unusually large transactions: Wed May 15 03:26:22 2002 Failure to extend rollback segment 27 because of 1581 condition FULL status of rollback segment 27 set. On Metalink I've found a couple of references to bug 228441. Following is one such reference. Sounds like one part of the work-around is to unset OPTIMAL which we do currently have set. I've looked through the docs and Metalink. I do see text for altering the OPTIMAL value but I don't see any reference to unsetting OPTIMAL. Is there a way to unset optimal in rollback segments that are currently online? Or do I have to create a bunch of new rollback segments from scratch without OPTIMAL specified and then roll them in and roll out the existing rollback segments.

Re: Users reading from rollback segments
Jeremiah : What I meant was that the delayed_logging_block_cleanouts parameter (=FALSE) will make the next reader of the block to cleanout that block. Now, if this parameter's value is TRUE (default in Oracle 7 and 8.0) the next reader will NOT clean out the block (it will read the rollback segment and generate the appropiate block image but it will not clean the block out). The delayed logging block clean out feature delays the redo for the cleanout blocks until it could be logged in combination with another redo for another change to the block. So if you have this parameter set in TRUE the block clean out will be made only when you'll make another change to these blocks. According to what Glenn was saying: As you mentioned, even if noone is reading from rollback at the time all transactions commit, a query may be executing which will access rollback later in its current run (which started prior to the commit). I think that there's a way you can be sure that noone will need to read some RBS blocks for a cleanout operation.

RE: Users reading from rollback segments
Thanks for the replies. I have all sorts of neat queries (which I can post) which show me gobs of information about my rollback segments (sizes, extents, optimal, shrinks, active transactions, block used by those transcations, ad infinitum...). HOWEVER, I still cannot find an answer to my original question; Is there a way to tell if anyone is reading from the rollback segments? Readers do not open transactions, correct? So they will not show up on the queries most of us are running against v$rollxxx and v$transaction. Where can I find out of someone is using the undo info in the rollbacks for read consistency? In other words, how do I find the readers (from rollback, not from the tables themselves)? I do not want to issue a shrink (and thus risk a ORA-01555) if people are still using the rollback for read consistency. To answer another reply's question: I am shrinking the rollbacks right before I run a large batch job, so as to give the job the maximum amount of space in the rollback tablespace. (I cannot utilize 'set transaction use ...' as this is an Oracle Apps job which actually does many transactions (re: purges)). -Original Message- From: Glenn Travis [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 26, 2002 2:38 PM To: Multiple recipients of list ORACLE-L Subject: Users reading from rollback segments Is there a way to tell if anyone is reading from the rollback segments?

RE: Users reading from rollback segments
XACTS is the NUMBER of active transactions in the rollback segment. 0 or 0. However, I am not looking for transactions, I am looking for queries reading from the rollback space for read consistency purposes. I found an answer to my second question and it is NO. You can take the rollback segment offline and it will succeed if it is being used. It will just go into an 'OFFLINE PENDING' state until all users are out. So I don't think I can use this logic. Question: How does Oracle know it is in 'use'? What does in 'use' mean? Active transactions plus readers? I would not think Oracle would take a rollback segment offline if users are reading from it (this doesn't necessarily mean they are holding active transactions). So if Oracle knows it is 'in use', how can I get that info too? -Original Message- From: Joan Hsieh [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 26, 2002 3:51 PM To: Multiple recipients of list ORACLE-L Subject: Re: Users reading from rollback segments SELECT segment_name, USN,EXTENTS,RSSIZE,HWMSIZE,optsize,xacts,aveactive,WRAPS,shrinks FROM V$ROLLSTAT, dba_rollback_segs where usn=segment_id xacts =1 is in use. otherwise it is 0. oracle 8.1.6 you can take an active rollback segment offline, but also kill the transaction. 8.17 supposed to fix the bug.

Re: Users reading from rollback segments
Since you cannot predict who might need to generate consistent reads from the RBS in the FUTURE, you cannot predict if you will cause ORA-01555 or not by shrinking. Your best bet is to get rid of people bloating up RBSs by limiting their growth, and enforcing the use of smaller transactions. That way you won't have to shrink so much. -- Jeremiah Wilton http://www.speakeasy.net/~jwilton On Tue, 26 Feb 2002, Glenn Travis wrote: Is there a way to tell if anyone is reading from the rollback segments?

RE: Users reading from rollback segments
People also obtain read consistency data from the rollback segments after transactions have committed. If a query began before someone else's transaction committed, but continues reading, then needs the reconstruct the data from before the commit, in needs rollback data that is both committed and impossible to predict. I suppose if you could determine that the age of all undo entries in the portion of RBS that you will obliterate through shrinking are older than any query currently running in the database, then you could be sure that the shrink will not cause an ORA-01555. But the flaw in your logic is believing that once committed, rollback entries will not be needed for read consistency. They very well may. Because a query doesn't know what rollback entries it may need further down the road, you can't predict if your shrink will obliterate undo entries that a long-running query might need in the future. You keep asking if we can tell who is reading the rollback segments. The answer is that it doesn't matter.

RE: Users reading from rollback segments
Glenn, An approximation of what you require *may* be worked out this way: 1. Snoop v$session_wait for all events that start with 'db file%' and see if P1 is in a list of data files that belongs to the RBS tablespace(s). If you do see sessions that have P1s indicating RBS files, then you *may* be reading Rollback. It is not necessarily on the older entries, but see below: 2. Track the start time of that Query from the SID - using V$SESSION and V$PROCESS. If the start time is reasonably old, then you *may* have an issue, as ORA-01555 errors can be expected for those queries that started *before* the entry you are going to zap via shrink was made. I have successfully used P1 and P2 to indicate the progress of a long running query by working out the segments being accessed and matching that with an EXPLAIN PLAN. This is especially useful if multiple table joins are involved.

I suppose if you could determine that the age of all undo entries in the portion of RBS that you will obliterate through shrinking are older than any query currently running in the database, then you could be sure that the shrink will not cause an ORA-01555. But the flaw in your logic is believing that once committed, rollback entries will not be needed for read consistency. They very well may. Because a query doesn't know what rollback entries it may need further down the road, you can't predict if your shrink will obliterate undo entries that a long-running query might need in the future. You keep asking if we can tell who is reading the rollback segments. The answer is that it doesn't matter. What you really need to ask is if we can tell who will need to read the rollback segments sometime soon. And you can't. -- Jeremiah Wilton http://www.speakeasy.net/~jwilton On Tue, 26 Feb 2002, Glenn Travis wrote: Hmmm. I think I CAN predict FUTURE needs of the rollback segments. If there are transactions using the rollback space, users MAY need it. If there are no transactions, then they won't. If I were able to know who is reading from rollback, I would know if shrinking might cause ORA-01555. Tell me if I'm off on this... Users will not read from the rollback segment unless they need read-consistent data due to an open transaction against the data they are looking for (thus reading the redo or undo info from rollback). Otherwise they read from the data segments (committed data). Oracle will not shrink the rollback segment if it contains open transactions. So, if there are no users reading from rollback and I issue a 'shrink' command, and it works, then the transactions are complete and any user coming in after that will read from the data segments. If there are no users reading from rollback and I issue a 'shrink' command, and it DOES NOT work, then the transactions are NOT complete and any user coming in after that will read from the rollback segments (the data is still there). If there ARE users reading from rollback and I issue a 'shrink' command, and it works, then users run the risk of getting ORA-01555 (the data MAY be gone). Which is exactly why I asked my original question (How do I identify READERS of the rollback segments?) :) -Original Message- From: Jeremiah Wilton [mailto:[EMAIL PROTECTED]] Since you cannot predict who might need to generate consistent reads from the RBS in the FUTURE, you cannot predict if you will cause ORA-01555 or not by shrinking. Your best bet is to get rid of people bloating up RBSs by limiting their growth, and enforcing the use of smaller transactions. That way you won't have to shrink so much. -- Jeremiah Wilton http://www.speakeasy.net/~jwilton On Tue, 26 Feb 2002, Glenn Travis wrote: Is there a way to tell if anyone is reading from the rollback segments? I would like to manually issue 'alter rollback segment XXX shrink;', but do not want to do so if there are users reading read consistent data from the rollback space (thus giving them the ORA-01555 error). Is there a way to check if the rollback segment is in use first? Can I try to take it offline?

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.

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.

Actually, the Hercules graphics is able to generate graphics. I had to settle for Hercules since I could not afford a color monitor(using a CGA card) back then. So I looked for games, etc. that had a Hercules graphics mode.

It replaced the limited CGA color pallete with patterns on the amber monitor. Sigh.

RE: Rollback Segments
SQL*Menu wasn't around in V5. IAP/IAG were there, and IAD came out in v5.1 (it was the first of the SQL*Forms). RPT/RPF were there too. And there was something called SQL*Calc which I never used (cuz you could do anything you wanted off of the DUAL table, so why bother with anything else). Now, in IAP, you could put in a %SW in the middle of the questions and IAG, while it was generating, would stop and ask you questions interactively until you entered %SW to have it return to the script. It was a handy way to add fields. User exits were the other big change with v5.1. Prior to that, you could specify any procedure of a C program linked with the form; afterwards, you had to use IAPXIT. Well, enough talking about the good old days. I'm off to do an applications upgrade on a production machine. See you some time next week. ;) Bambi (the geezer). -Original Message- Sent: Tuesday, February 19, 2002 1:43 AM To: Multiple recipients of list ORACLE-L How about iag/iap ? And rpt ?

Rollback Segments
Hello DBAs Is there a command that tells me which rollback segment is being used by current transaction? Also, can you force a session to use particular rollback segment? I have used in the past the command: set transaction use rollback segment rbs_01 but the named rollback segment seemed to be used until the end of tranasction. After a commit or rollback a different rollback segment could have been used by Oracle. I wonder if there is a way to make sure that once a user logs in, a particular rollback segment is used.

Re: Rollback Segments
Hi Witold, This is exactly the way it is documented to work. After each commit you must reissue the set transaction use rollback segment rbs_01 statement. John [EMAIL PROTECTED] wrote: Hello DBAs Is there a command that tells me which rollback segment is being used by current transaction? Also, can you force a session to use particular rollback segment? I have used in the past the command: set transaction use rollback segment rbs_01 but the named rollback segment seemed to be used until the end of tranasction. After a commit or rollback a different rollback segment could have been used by Oracle. I wonder if there is a way to make sure that once a user logs in, a particular rollback segment is used.
