The pdb_archive_path configuration parameter identifies where Replication Agent expects to find archived Oracle redo log files.
If Replication Agent for Oracle is configured to truncate archive redo logs without using the Oracle Recovery Manager (RMAN), make sure Replication Agent has permission to truncate the Oracle archive redo logs. Oracle can be configured to archive to different locations and Oracle finds these locations using the destination column of the V$ARCHIVE_DEST system table. Replication Agent must have read access to the archive redo logs and the directories containing them.
You can configure Replication Agent to remove archived logs from the location specified by pdb_archive_path, using the pdb_archive_remove configuration parameter. This allows Replication Agent to remove archived log files that are no longer needed to support replication. If pdb_archive_remove is set to true, Replication Agent must have update authority to the archive log directory and delete authority on the individual archive log files. If rman_enabled or the pdb_archive_path configuration parameter is pointed to an ASM path, then update authority to the archive log directory and delete authority on the individual archive logs are not required.
