Any data in the PDB that has exceeded the retention period (described in "Manager" in the Technical Guide) will be deleted from the PDB as part of the PDB maintenance processing that is executed at 2:00 AM each day.
While PDB maintenance processing is in progress, access to the PDB (such as executing PDB commands or displaying the Summary view and Drilled-Down displays and the Analysis/Report view of the Console) may become temporarily impossible.
In this case, repeat the operation after the PDB maintenance processing has completed.
