Failover Overview

Failover provides a backup sync server that takes over if the primary server fails.

  • In the event of kjs or kcs failure
  • In the event of kxs failure

If the kjs or kcs fails, the Administrative Server (kas) restarts the kjs or kcs.

The Administrative Server:

  1. Restarts the Executive Server (kxs) in the currently appropriate role.
  2. Stops the Java (kjs) and C++ (kcs) servers.
  3. Restarts the Java (kjs) and C++ (kcs) servers.

A promoted primary sync server can also promote an alternate server to ensure that there is always a backup sync server.
