Pruning data from the Performance Data Warehouse database

Use the prune command to remove data that you no longer need from the Performance Data Warehouse database. The prune command removes data that is older than the number of days old specified by the -daysOld parameter.

Note: The prune operation fails if the schema name used in Performance Data Warehouse database or the user name set in the corresponding datasource was changed after the Tracking Group tables were created.
Tip: Run the prune command during a time when the server is not busy.
