What Happens In Case of a Failure?

In a high availability deployment, the clustering solution software queries the primary server for availability at a fixed interval. If the primary server fails to respond within the predefined period, the clustering solution software and CA ControlMinder do the following:

1. The clustering solution software stops all the Enterprise Management Server services running on the primary server.
2. The clustering solution software starts all the Enterprise Management Server services on the secondary server.
3. CA ControlMinder endpoints attempt to connect to the secondary server and continue working.
4. When the clustering software solution stops Enterprise Management Server services on the primary server, any users who are logged in to the application are logged out. To continue using the application, the users must log in to CA ControlMinder Enterprise Management again.
