Hi J. Dex, Which user are you using to delete/truncate from aud$ table. Starting 10g only sys (sysdba) can delete from aud$ table. - Mayen "J. Dex" <cemail_219@xxxxxxxxxxx> Sent by: oracle-l-bounce@xxxxxxxxxxxxx Mar 22 2010 09:13 AM Please respond to cemail_219@xxxxxxxxxxx To oracle-l@xxxxxxxxxxxxx cc Subject aud$ delete I have auditing of create session set up on my 10.2.0.4 database. I want to set up a cron job that will delete all records from aud$ that are older than 30 days but I am having issues with the delete statement as nothing is showing up in the timestamp field. TRUNC doesn't seem to work either. Does anybody already have this set up and could let me know what the correct statement is? Hotmail: Trusted email with Microsoft’s powerful SPAM protection.
