TimesTen performance metrics configuration allows you to modify the maximum snapshot count and the maximum snapshot retention size. These configuration settings are useful both in preventing your database from running out of permanent space and in allowing you to save more snapshots.
Once the maximum snapshot count or the maximum snapshot retention size is reached, TimesTen removes the oldest snapshots to free up permanent space. By default, the maximum snapshot count is 256 and the maximum snapshot retention size is 256 MB.
To edit the TimesTen performance metrics configuration for a database, make sure you are on the main SQL Developer page.
Right-click the name of the database and select TimesTen Performance Metrics, then select Edit Configuration.
The TimesTen Metrics Configuration dialog displays and you see the current configuration for the TimesTen metrics.
The Prompts tab of the TimesTen Metrics Configuration dialog is selected. In the Maximum Snapshot Count field, specify a numeric value to indicate the maximum number of snapshots. By default, the maximum number of snapshots is 256.
In the Maximum Snapshot Retention Size (MB) field, specify the maximum total size of all stored snapshots, in megabytes. By default, the maximum snapshot retention size is 256 MB.
Click Apply.
You have applied the new TimesTen Metrics configuration settings.
