Procedure documentationUpdating Compression Rates with BR*Tools

 

You can use BR*Tools for Oracle to update compression rates. BRBACKUP performs the update. If you use devices with hardware compression, we recommend updating compression rates monthly, as this helps BRBACKUP to make the most efficient use of your tape volumes.

Prerequisites

Make sure that you have set the necessary BRBACKUP parameters in the initialization profile init<DBSID>.sap, because BRTOOLS uses these when it calls BRBACKUP.
