ORA-16069:

Archive Log standby database activation identifier mismatch
Cause: The activation identifiers of the Primary and Standby database do not match. Remote archival of redo log files is not allowed to incompatible STANDBY database instances. This can occur when trying to apply an incorrect archive log to a standby database, or when trying to archive to a standby database that does not match the primary database.
Action: Take the necessary steps to create the required compatible STANDBY database before retrying the ARCHIVE LOG processing.
