Creating Snapshots

Manually creating snapshots is usually not necessary because AWR generates snapshots of the performance data once every hour by default. In some cases, however, it may be necessary to manually create snapshots to capture different durations of activity, such as when you want to compare performance data over a shorter period of time than the snapshot interval.

To create snapshots: 

1. From the Database Home page, click Performance.

   The Performance page appears.

2. Under Additional Monitoring Links, click Snapshots.

   The Snapshots page appears with a list of the most recent snapshots.

3. Click Create.

   The Confirmation page appears.

4. Click Yes.

   The Processing: Create Snapshot page is displayed while the snapshot is being taken.

   After the snapshot is taken, the Snapshots page reappears with a Confirmation message.
