Creating cluster members

Why and when to perform this task

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.

Steps for this task

  1. Go to the Cluster Members page. Click Servers > Clusters in the console navigation tree. Then, click a cluster in the collection of clusters and click 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 on which the server will reside.
    3. Specify the server weight. The weight value controls the amount of work 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 servers' workload. The value can range from 0 to 100.
    4. Specify whether to generate a unique HTTP port.
    5. Specify whether to create a replication entry for the server.
    6. Specify the server template.
    7. Click Apply to finish the cluster member. Repeat steps 1 through 7 to define another cluster member.
    8. Click Next.
    9. Review the summary of information on new cluster members and click Finish.
  3. Click Save on the administrative console taskbar and save your administrative configuration.
  4. (Optional)   If you are adding a new cluster member to an existing cluster, manually add a replication entry to this new cluster member.
    When a new cluster member is added to an existing cluster, a replication entry is not automatically configured as part of the replication domain for that cluster. To prevent errors from occurring when the cluster is started, you must manually add a replication entry to this new cluster member:
    1. In the administrative console, select Environment > Internal Replication Domains.
    2. Click on the domain containing your cluster, and then select Replicator Entries
    3. Select New and create a replicator that has the same name as the new cluster member for which it is being created.
    4. Select this new cluster member from the drop down list and enter port numbers for the Replicator port and the Client port such that they do not conflict with any other services running on that node.
    5. Click OK.
    6. Save and Synchronize changes with Nodes. Restart your entire cluster to ensure the new replication entries are visible.
  5. 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.
