A BIG thanks to Jared & Bruce for all your efforts guys. And as bruce says "See you in a minute on the new list". Thank you, Venu! -Original Message- Bruce A. Bergman Sent: Thursday, January 22, 2004 9:44 PM To: Multiple recipients of list ORACLE-L Yes, this is legitimate. Jared and I have been talking recently about this. This list has just outgrown what Fat City can handle. While I'd like to think that I've always provided adequate-to-good service for the list, it's never been "great", and with the list growing, and traffic growing, my concern is that I just won't be able to continue to give the list good service. It makes me sick to think that, because I really have enjoyed giving back to the Oracle-L community, and because y'all have supported ME so well in the past, but I just don't want to see anything deteriorate simply because the volume exceeds what we can handle here. The list archives here will be available as long as Fat City continues to be in existence, so those of you who are searching for old topics are quite welcome to use the facilities here. It won't be going away. Jared has always been an awesome list owner, and I know he'll continue to make sure the list is successful.

RE: Change based recovery
Fermin, I don’t want to de-motivate you, but I really doubt whether your backup strategy really works. The command that you have mentioned below will NOT do a complete recovery as it’s 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 it’s 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!

I've used this method on a hot backup to roll the database forward. Also, don't bother restoring the redo logs as you will be overwriting / recreating them with the "alter database open resetlogs". One more thing I noticed. Your until change number looks to me like an archive sequence number rather than the SCN it needs to be. Hope this helps.

RE: Change based recovery
Fermin, Yes, It can be done!! Just with your cold backup and your archive logs. Basics: 1) Get this straight - A cold backup does not require any kind of recovery. When you restore a cold backup your DB will be old but will NOT require any recovery. 2) If you want to bring a old database to current time, you have to apply the archive logs. In case of a cold backup you cannot (read till the end) do it as your control files do not recognize newer archive logs generated after the backup was taken. The Work around is to re-create the control file using the ‘create control file’ script (see below) and then recover the database using the command ‘RECOVER DATABASE USING BACKUP CONTROL FILE’, This command will ask you for the archive logs; on supplying the archive logs, the database will be recovered further. 3) In case of a hot backup the backup is in-consistent. So after restoring a backup it WILL ask for recovery which will happen from the archive logs. This is same as the above but there is no Downtime involved in hot backups. Creating control file: The script to create the control file can be generated using the following command: SQL> ALTER DATABASE BACKUP CONTROL FILE TO TRACE; This will create a .trc file in the UDUMP directory of the database. You will have to edit it before running to create the control file. Browse thru Metalink for more info on this. Hope this helps! Cheers!

RE: Change based recovery
Hi,
When you are restoring from a cold backup
you don’t have to recover and your database will be old.
If you want to bring it to current time
then recreate the control file and recover it using ‘RECOVER DATABASE
USING BACKUP CONTROLFILE UNTIL CANCEL’; this will ask you for archive
logs and then you have to supply them.
Create the control file from a trace file
generated on the running database using the following command:
‘ALTER DATABASE BACKUP CONTROLFILE
TO TRACE’;
Cheers!

RE: 9i - Dynamic SGA - SGA_MAX_SIZE
Stephen, That's the way it's meant to work. This is how Oracle guarantees that you can grow upto the value of SGA_MAX_SIZE. Look at the case below: DAY 1: you have your sga_max set to 100m but you are currently using only 50m of it. DAY 2: you want to use all 100m and you try to increase the sga size, but some other app has used rest of the physical memory and there is no sufficient memory available, at this stage oracle has to error out saying 'insufficient memory', but in reality it does not!! In reality: On DAY 1, Oracle tries to occupy all 100m in the memory so that it doesn't have any issues in future... this way you have 100m reserved for oracle, use it whenever you want to use it.

RE: Stored procedure memory problem
Thanks a lot guys! Now I have some understanding about how oracle handles cursors. Mark: can you please point me to some document or site which could put some more light on what you said below. Few hundreds of thousands was NOT typo... 10 - 50 -Venu -Original Message- Sent: Wednesday, December 18, 2002 1:04 PM To: Multiple recipients of list ORACLE-L It's important to realize that Oracle does not materialize all the rows to be returned from a cursor in memory. If you do 'select * from one_million_row_table;', at no time are all one million rows going to be in the PGA. However, there are cases where some or all of the data DOES have to be materialized, such as in a sort. This is why the sort_area_size and sort_area_retained_size parameters are important. They govern how much memory a single process can consume. Sorts larger than that threshold will automatically write to disk. If you're on 9i, you may wish to investigate pga_aggregate_target instead. You said "few hundreds of thousands"?? Is that a typo?? (Perhaps you meant "hundreds or thousands"??) Something else to consider is a shared server (aka MTS) configuration for large numbers of users in an on-line type environment, where the users have a large amount of think time. Shared server is a bad idea for batch type users, but could be a memory saver for an environment where there are thousands of users connected, but with long think times, the concurrency is limited. Hope that helps get you pointed in the right direction. -Mark On Tue, 2002-12-17 at 22:53, Venu Gopal Andem wrote: > A small question to all gurus on the list... > > I have a stored procedure (SP) which runs at specific intervals.

Stored procedure memory problem
A small question to all gurus on the list... I have a stored procedure (SP) which runs at specific intervals. It fetches a list of user names and few (2 columns) of their details into a cursor and processes them one by one in a cursor FOR loop. Now my question is, Is there a chance of the SP running out of memory when the number of users increases (may be a few hundreds of thousands). If yes how to estimate the maximum number of user names my cursor can handle? Is there any calculation for this? How to overcome this problem? Is there anything else that has to be taken into account when doing this? Thanks in advance!

RE: Installing 8.1.7.3 along with 8.1.6.0
Thanks a lot for the info.. Couple of clarifications req... Will the existing 8.1.6 DB still exist after migration or will it be changed to 8.1.7.4? At the time of installation will I have to shutdown the existing DBs?? Thanks, Venu G. -Original Message- Sent: Wednesday, December 11, 2002 2:49 PM To: Multiple recipients of list ORACLE-L You can install 8.1.7 on a machine that has 8.1.6. During the install you can just migrate the database to 8.1.7 and save all the hassle. The migration process show you a screen with the 8.1.6 databases installed on the machine and allow you to choose which one you will migrate. This way you do not have to export/import/notify users etc. Yechiel Adar Mehish - Original Message - To: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> Sent: Wednesday, December 11, 2002 5:33 AM Hi, We have 8.1.6.0 installed on a NT server. There are 2 databases(development of size 120MB when FULL export is done) already running on the system. Now our requirement is to install 8.1.7.4 and bring one of the DB into this environment. My plan of approach is as follows, any feedback, comments are most welcome: 1) Shutdown all the existing databases 2) Install 8.1.7.3 from cd's and apply 8.1.7.4 patch to bring it to ver 8.1.7.4 3) Bring the 8.1.6 databases UP 4) Create a new database in 8.1.7.4 environment 5) Export the 8.1.6 database and import it into 8.1.7.4's database (I decided to do it with export as the DB was not very large) 6) Update the devolopers with the new DB's SID and etc. details 7) Drop the 8.1.6 database once devolopers are satisfied with the 8.1.7.4 database Questions: 1) Are there any ramifications of installing 8.1.7.4 engine on the same system where 8.1.6 is already present? Obviously in a different home. 2) Database migration in this scenario is done using EXP/IMP. Is this ok? Why? Any better alternatives? 3) Do I have to really shutdown the databases and other oracle services before starting the 8.1.7.4 installation?
