Goal

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.
