ExpressConnect for Oracle, Replication Agent™, and Enterprise Connect™ Data Access are available as a product called Replication Server Options that are available separately from Replication Server. You must have Replication Server to obtain Replication Server Options.
Replication Server Options provide bidirectional replication across distributed, heterogeneous systems. You can use the Replication Server Option components to implement replication on the Microsoft Windows and UNIX platforms.
Replication Server Options are available in three data-source-specific versions: Microsoft SQL Server, Oracle, and IBM DB2 UDB. See the Release Bulletin for Replication Server Options 15.5 for Linux, Microsoft Windows, and UNIX for details about supported platforms and compatible Replication Server versions.
