Chapter 4: Using the Replication Coordination Module

How the RCM detects Replication Server failure

If the RCM cannot log in to the Replication Server, the RCM:

Notifies the system administrator about a possible Replication Server failure and logs the failure in the system log.
Waits a configurable interval of time to see if Replication Server recovers. This is required because network problems might prevent the connection.
Continues with the failover process by marking the active Adaptive Server as DOWN and switching all users to the standby Adaptive Server.
