The Sybase® Replication Server® Options can be purchased separately from Replication Server, or as part of Replication Server Heterogeneous Edition (RSHE) or Replication Server Real-Time Loading Edition (RTLE).
Replication Server Options
Use Replication Server Options with Replication Server for bidirectional replication across distributed, heterogeneous systems, which allows you to perform different operational and decision-support tasks. To obtain an option, you must already have Replication Server.
Replication Server Heterogeneous Edition
Replication Server Options and Replication Server are also sold together as part of the Replication Server Heterogeneous Edition (RSHE).
Replication Agent
Replication Agent extends the capabilities of Sybase Replication Server by allowing non- Sybase database servers to act as primary data servers in a replication system based on Sybase replication technology.
