Weird behavior with VARCHAR fields (was: ORA-01403 error, help!!!)
Thank you all of you who answered to my first question. No, the problem has nothing to do with permissions. The record existed in the table, but here it is what I discovered. Can anyone explain please? It may be the normal Oracle behavior, but I believe it was not working like this under 7.3.4 (now we have 8.0.3). I can not confirm though. TTDSLS805501 table definition is as follows: NameNull? Type T$ORNO NOT NULLNUMBER T$USER NOT NULLCHAR(10) If I do an INSERT like the following: INSERT INTO TTDSLS805501 VALUES (151124 , 'exped9') The value 'exped9' for the field T$USER is 6 characters long, while the definition has got 10. After the insertion, I find that the field for the new record is 10 chars long, the last 4 characters being filled with blanks. But here comes the weird behavior. If I construct the 2 following SELECT on this table from SQLPlus, both work OK and return the expected row: SELECT t$orno FROM TTDSLS805501 WHERE t$user = 'exped9'; - 1 row returned SELECT t$orno FROM TTDSLS805501 WHERE t$user = 'exped9'; - 1 row returned But within a stored procedure and using a local variable the following will work OK: SELECT t$orno INTO eskaria FROM TTDSLS805501 WHERE t$user = my_var; where my_var is of type VARCHAR2 and has got the value 'exped9' Whilst the following will come up with the ORA-01403 error: SELECT t$orno INTO eskaria FROM TTDSLS805501 WHERE t$user = my_var; where my_var is of type VARCHAR2 and has got the value 'exped9' Is this normal behavior? why does not the SELECT t$orno FROM TTDSLS805501 WHERE t$user = 'exped9'; statement return 0 rows in the first place?

RE: Weird behavior with VARCHAR fields (was: ORA-01403 error,
Yet I do not understand why it returns a row in SQLPlus and it does not in a stored procedure... The problem is now fixed, but I'd like to know the reason it won't work leaving it as it was. It also fails if I put a string instead of a variable in the stored procedure. Thanks!

RE: Multiple Datafiles and performance?
In my experience, spreading datafiles across volumes (specially if you are careful not to locate the a table's datafiles and its indexes datafiles in the same drive) greatly increases performance. As for the file size, I can not say because I have not tested it, but I think it should have no real impact compared to splitting it. Reorganizing the database regularly is a better way to optimize performance. .. Fermín Bernaus Berraondo Dpto. de Informática SAMMIC, S.A.

Oracle 8.1.7.4 Win2k What is the consensus on datafile sizing and the impact/overhead multiple datafiles have on performance?

Is it better to keep them all uniform in size? I would think having multiple datafiles that could be spread across drive volumes would be beneficial, am I wrong?

RE: Change based recovery
Well I am quite de-motivated actually!! but at least it is good to know I was (partially) wrong and that I will feel safer after reading your comments, thanks! I am really in doubt now, but I remember when we were testing we did recover all datafiles (the ones that are stated in the v$datafile table) from a cold backup exceptcontrolfiles and redolog files; we were able to restore the whole database with the commands I wrote down in my first message. If I am still wrong, will you please be kind enough to tell me which are the exact commands needed to recover the whole database from a cold backupif I have no online backups and I lose everything except for the archived logs? can it really be done? Thank you so much!

The command that you have mentioned below will NOT do a complete recovery as its a cold backup. As for your questions: 1) You can recover your entire database in either case (Cold or Hot), If you have your archive logs. Difference being, You have recreate your control file if its a cold DB backup and recover the DB using BACKUP CONTROL FILE option. 2) Lets look at it the other way; you do NOT need any downtime for Hot backups while you need downtime for Cold backups. Downtime could be very expensive depending on the type of database. Secondly, you can take a hot backup very frequently as it does not involve any downtime. Recent backup means less recovery is required and less time to bring up the database. Let me know if you need anymore info. Cheers!

2G. (Other than time to recover from datafile loss) It is probably safe to assume that the datafiles exist on a RAID 5. (for now) 3) Why the recommendation to take a Win2k datafile to just over 2G? For future apps I am pushing for optimal recommendations that go for more raid 1 sets or raid 10 over the Raid 5. This should allow for more flexibility for spreading out the i/o. Thanks for your patience and all the help. David Phillips Support DBA BAARF Member #30 -Original Message- Sent: Thursday, August 07, 2003 9:59 AM To: Multiple recipients of list ORACLE-L Win2K. If you decide to increase the filesize, do it to more than 2G (doesn't have to be by much). Of course, you didn't mention autoextend so this may not be an issue. Also, just how many physical disks do you have? Logical disks are not the issue. If you're going to get any increased performance you should be putting the second datafile on a second physical disk. Any how come you're not using some sort of RAID device (or don't you have your logical drives striped across your physical drives)? There is no easy answer to your question without an understanding of the reality of your disk layout.

As for the file size, I can not say because I have not tested it, but I think it should have no real impact compared to splitting it. Reorganizing the database regularly is a better way to optimize performance. . Fermín Bernaus Berraondo Dpto. de Informática SAMMIC, S.A.

TOAD vs BMC's XRAY

The two I know are Toad and BMC's XRAY but since I do not know them very well I have difficulties deciding which of them is the best.

RE: Rollback Segs

RE: Rollback Segs
Yes you are right, sorry but I made a mistake, since we are using Baan IVc4 which works against Oracle we have no means to interfere with its transactions when they are commited to Oracle and we can not modify them so that it uses a specific rollback segment, so the only way for us to do it is to disable all except the one we want it to use. -Mensaje original-De: Lee Cullip [mailto:[EMAIL PROTECTED]Enviado el: miércoles, 16 de julio de 2003 10:54Para: Multiple recipients of list ORACLE-LAsunto: RE: Rollback Segs set transaction use rollback segment only works if it's the first statement in your transaction, an easy way to make sure this is the case is to issue a commit directly before issuing this statement.

RE: Cannot allocate new log - checkpoint not complete
Dennis, This is our actual distribution: Datafiles belonging to data in a separate disk, name it /baandata Datafiles belonging to index in a separate disk, name it /baanindex And 3 redolog files, two of them in another two separate disks, and the third one located in the same device as the data files (/baandata). All of them are mirrored disks. Your comment makes sense, but if keeping datafiles and one of the redolog files in the same device should affect performance, then I wonder why the cannot allocate new log, checkpoint not complete message is affecting to the 3 redolog files and not only to the one located in that datafile device. I did not think on this. Anyway I have no more disks in which I can split the redologs... I can not wait for your comments!

Up to you if these are important / significant to your users. If you make them bigger and you have a standby database then the standby might end up being further behind production (unless you have a script to workaround this) and also in this case you may then not get the files transferring successfully (depends on your network etc). Also, if you make them bigger and you have a loss of all redo logs (hopefully unlikely if they are mirrored on mirrored disks) then you will lose more data as it will be a longer period of time since the last archive log was created. And what about your archive log management scripts - do they keep x days worth of files (in which case the volume of archive log on disk will not change) or do they keep y files - in this case the volume of disks would increase unless the script(s) are altered.

RE: how to calculate table size
Hi Ravindra, Use the following, supposing your db_block_size is 2048 (change as appropiate). SELECT segment_type, segment_name,BLOCKS*2048/1024 Kb FROM DBA_SEGMENTS WHERE OWNER=UPPER('owner') AND SEGMENT_NAME = UPPER('table_name'); You should substract emptied blocks from this table, using: ANALYZE TABLE owner.table_name ESTIMATE STATISTICS; SELECT TABLE_NAME, EMPTY_BLOCKS*2048/1024 Kb FROM DBA_TABLES WHERE OWNER=UPPER('owner') AND TABLE_NAME = UPPER('table_name'); This will give you how many kb are occupied by empty blocks, so substract this amount from the prior result.

RE: how to calculate table size
I've been using this query for both normal and empty tables and works so far. For those tables with no data in them (or that have suffered no deletion) you can ommit the second query since the table should not have any emptied block. Emptied blocks are those who have been occupied by data from the table but that have been deleted; for these, Oracle marks them as deleted but are still asigned to a table. I do not know if you want to consider this free space as part of the table or not. There is a way to deallocate unused space to a table that has been previously used. You must use 'alter table ... deallocate' for that. You have explanations on this in the manual, check: http://download-west.oracle.com/docs/cd/A91202_01/901_doc/server.901/a90125/statements_32.htm#2080417 I am sending this mail to the list as well, I am a learner and do not consider myself an expert, maybe someone else can join and comment something. -Mensaje original- De: Basavaraja, Ravindra [mailto:[EMAIL PROTECTED] Enviado el: martes, 01 de abril de 2003 20:41 CC: '[EMAIL PROTECTED]' Asunto: RE: how to calculate table size Hi Fermin, Thanks for your reply.

Dennis, you seem to be have a master in Oracle! please can you help, I can see the SPID column under table v$process, but how do I link it to table v$session so that I actually know which UNIX process it corresponds to.

RE: Oracle Enterprise vs Standard
We have BAAN IVc4 and Oracle Enterprise edition at our site. Enterprise Edition has got some advantages over the Standard Edition which would be too lenghty to explain here, but we are not taking advantage of them and, besides, baan does not exploit Oracle's facilities too much and Standard should be enough. So why do we have Enterprise instead of Standard? because Oracle does not provide the Standard edition for our 64-bit HP-UX machine.
