The pdb_archive_path configuration parameter identifies where Replication Agent expects to find archived Oracle redo log files.
In an Oracle RAC environment, each Oracle instance can be configured to point to one or more archive log destinations. To support replication, all instances in the Oracle RAC cluster must provide a copy of their archive log files to a shared location that Replication Agent for Oracle can use to access all archived redo logs. Configure pdb_archive_path to point to a location to which all Oracle instances write archived log data. Replication Agent must have read access to this directory and all archived redo logs within that directory.
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.
