Replication Agent for Oracle supports only the Oracle database server.
Replication Agent for Oracle must be installed on the same kind of UNIX or Microsoft Windows host as the primary Oracle data server. Direct access to the Oracle logs is necessary if pdb_archive_remove is true and rman_enabled is false. See the Replication Agent for Oracle Reference Manual.
Primary data server and primary database are online and configured properly for your production systems. See the documentation provided by your database software vendor.
Replication Server is installed, configured, and running. See the Replication Server installation and configuration guides for your platform.
