Overview

Use this task to create application servers to be members of a configured cluster.

Before you begin, you need to have created a cluster.

You create a cluster member to represent an application server in a cluster. To create a cluster member, view information about cluster members, or manage members of a cluster, use the Cluster Members page.

Note: With WAS v6, one can now upgrade a portion of the nodes in a cell, while leaving others at the older release level. This means that, for a period of time, you might be managing servers that are at the current release and servers that are running the newer release in the same cell. Note that in this mixed environment, there are some restrictions on what one can do with clusters and cluster members:

 

Procedure

  1. Click...

    administrative console | Servers | Clusters | cluster | Cluster members

    The Cluster members page lists members of a cluster, states the nodes on which members reside, and states whether members are started, stopped or encountering problems.

  2. Click New and follow the steps on the Create new cluster members page.

    1. Type a name for the cluster member (application server).

    2. Select the node for the server.

    3. Specify the server weight.

      The weight value controls the amount of work that is directed to the application server. If the weight value for the server is greater than the weight values assigned to other servers in the cluster, then the server receives a larger share of the workload. The value can range from 0 to 20.

    4. Specify whether to generate a unique HTTP port.

    5. Specify the server template.

    6. Click Apply to finish the cluster member. Repeat these steps to define another cluster member.

    7. Click Next.

    8. Review the summary of information on new cluster members and click Finish.

  3. Click Save to save your administrative configuration.

  4. To examine a cluster member's settings, click on the member's name under Member name on the Cluster members page. This displays the settings page for the cluster member instance.

 

What to do next

If you are finished configuring your cluster, you can create a backup cluster and start the cluster.

You can automate the task of adding cluster members by using scripting.
