Opening the primary database with the RESETLOGS option or using the CREATE CONTROLFILE command with the RESETLOGS option invalidates the standby database. If you reset the on-line logs of the primary database you must re-create the standby database by following the standby database creation procedures.

Activating a standby database resets the on-line logs of the standby database. You can follow the creation procedures to create a standby database from the activated database.
