Replication Agent supports only certain database servers on Linux, UNIX, and Microsoft Windows platforms.
Replication Agent for Oracle must be installed on the same platform 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 Reference Manual.
Replication Agent for Microsoft SQL Server must be installed on a Microsoft Windows host from which it can directly access the primary Microsoft SQL Server transaction logs.
Replication Agent for IBM DB2 Universal Database (UDB) must be installed on the same UNIX or Microsoft Windows host as the UDB server or the UDB Administration Client.
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.
