Sybase Replication Server 15.5 allows you to create and maintain a warm standby environment for the Oracle database. To support warm standby:
Replication Agent must be installed and initialized on both the primary and standby side. Replication Agent on the standby side should run in standby mode.
Replication Agent should be configured to use the Replication Server physical connection instead of the logical connection.
A new configuration parameter, ra_standby, has been added to support this feature. This parameter identifies whether Replication Agent works in a standby mode. See Chapter 2, “Configuration Parameters” in the Replication Agent 15.5 Reference Manual.
See the Replication Server 15.5 Heterogeneous Replication Guide for detailed steps about creating and managing warm standby for Oracle.
