In Replication Server 15.5, you can create and maintain warm standby applications for Oracle database.
There are tasks that the Replication Server system administrator has to perform manually to create the warm standby setup for Oracle databases. See Chapter 12, “Managing Heterogeneous Warm Standby for Oracle” in the Replication Server Heterogeneous Replication Guide for complete information.
A new configuration parameter, ra_standby, has been added to support Oracle warm standby applications. This parameter identifies whether Replication Agent for Oracle works in a standby mode. See Chapter 2, “Configuration Parameters” in the Replication Agent 15.5 Reference Manual.
For Adaptive Server, administrators can continue using the rs_init utility to set warm standby environment. See the Replication Server Administration Guide Volume 2.
