Use the Profile Repositories preferences to register and unregister Oracle 9i, 10g and 11g supported version of Oracle data sources as profiling repositories. A data source must be added to the list of SQL Query Tuner DB Optimizer Managed Data Sources before it can be used as a repository.

To access the Profile Repositories PreferencePreferences, select Preferences > Profile Repositories.

If you choose not to delete the profiling sessions, they will still be available from either the Profiling Repository node in the data source entry in Managed Data Sources or from the Profiling Repositories node. You will not be able to save profiling sessions to the unregistered repository until you register it.
