This is a text description of farmpage_instances.gif, which shows a portion of the OracleAS Farm page in the Application Server Control Console. Specifically, the image shows the Standalone Instances table, which by default lists the instances that are currently part of the farm.

Above the table, the Join Cluster button allows you add selected instances in the table to an OracleAS Cluster. For each instance in the table, Application Server Control provides the name of the instance, the host on which the instance resides, and the path to the Oracle home for the instance.
