Use the large pool to store what? I can think of 3 aspects of a transaction: - Rollback (you've probably read about SET TRANSACTION) - SQL statements, execution plans (more an issue with bind variables) - Data blocks It sounds like you might be thinking of data blocks. You didn't mention your Oracle version, but from 8i on you can define 3 buffer pools. The normal one is DEFAULT. You can also define a KEEP and RECYCLE pool. Someone on this list (sorry I can't recall who) pointed out that there isn't anything magic about those labels. If your transaction uses different tables from the other transactions, you could create what is needed for those tables in one of those pools, assign the tables to that pool, and this would minimize the interference. If all the transactions hit pretty much the same tables, then Oracle is probably reusing the blocks anyway. Hope this responds to your question.

Is it possible to use the large pool for a specific transaction? We run alot of large batch DML statements over night. We have one that involves an 8GB table. The blocks from this table are being knocked out of the buffer cache by shorter and quicker batches. Id like to find to store this transaction in memory without having to worry about them getting knocked out of memory. Cache wont do it. It will stick get pushed out. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: <[EMAIL PROTECTED] INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- 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).
