Deleting a Baseline

To conserve storage space, you may want to periodically delete unused baselines stored in the database.

To delete a baseline: 

1. From the Database Home page, click Server.

   The Server page appears.

2. Under Statistics Management, click AWR Baselines.

   The AWR Baselines page appears with a list of existing baselines displayed.

3. Select a baseline and click Delete.

   The Confirmation page appears.

4. Select whether to purge the underlying data associated with the baseline.

   The underlying data includes the individual snapshots preserved in the baseline and any statistics that are computed for the baseline. Do one of the following:

   • To delete the underlying data, select Purge the underlying data associated with the baseline.

   • To preserve the underlying data, select Do not purge the underlying data associated with the baseline.

5. Click Yes.

   The AWR Baselines page reappears. A message informs you that the baseline was deleted successfully.
