Administer cluster members

Cluster members represent application servers in a cluster. For descriptions of cluster member properties, see Cluster member settings.

Note: The name of a cluster member cannot be used elsewhere in the cell. For example, Cluster1 can have multiple members named server1, but no server in the cell outside of Cluster1 can be named server1. If one or more cluster members in other clusters are named server1, lookups that resolve to an object on a cluster, or a single server involved in the name conflict can fail. It is recommended that you assign a unique name to each cluster member.

For instructions on administering cluster members, see these sections:

• Configure cluster members
