This document describes the manual steps for Application Server Control (ASC) failover in Application Server version 10.1.3.

In Application Server 10.1.3, AS Control has been re-architected as a J2EE application called ascontrol. The OC4J instance where the ascontrol application is running is known as the OC4J Administrative Instance. The idea behind this was to make ASControl more of a lightweight architecture that would not require a lot of system resources.

If more than one ascontrol application is running in your cluster topology, the following warning message appears at the top of the Cluster Topology page:



You have more than one instance of the Application Server Control application
running in this cluster. This is not a recommended configuration and could lead
to unexpected problems. Please stop the additional instances of Application
Server Control or disable routing to these instances.


Each Oracle Application Server instance has its own Application Server Control that is used to manage the instance. After joining a cluster, only one Application Server Control is required to manage the entire cluster and the other ones must be stopped.
