Hi,

You need to TRUNCATE your SYS.AUD$ table to release the storage. If you need to keep certain records, export them, then re-import them after truncating the table.

Best regards.

Hi,

Deleting rows will not release space allocated to the AUD$ segment. You need to DROP/CREATE or TRNCATE this table. This is clearly documented in the Administrators guide.

Best regards.

Hi,

You are auditing too much. Scale down on what you are auditing.

Again, please read the Oracle Administrators Guide (especially the section on "Keep Audited Information Manageable") as this is all very well documented.

Best regards.

it's better to move the auditing information to other tablespace. Please find the metalink note: 72460.1 for more on that. Redo log contention can happen for many reason. Your lgwr is slow or arch & lgwr is contending for each other. There could be many other.
