Creating a cluster by using an existing Common Event Infrastructure server as a template

You can create a new cluster by specifying an existing Common Event Infrastructure server as a template.

Before you begin

Before you can create a cluster using this method, you must have an existing server that is fully configured for Common Event Infrastructure. This includes deploying the event service application and configuring the event database.

About this task

To create the cluster:
Procedure
  1. Follow the typical WebSphere® process for creating a new cluster, using the existing Common Event Infrastructure server as a template for the first cluster member. When the first member is created, the following steps take place:
    • Common Event Infrastructure resources available at the scope of the existing server are copied to the new cluster scope.
      Default database: If the existing server is configured with the default Derby database, the database resources are not copied to the cluster scope. The default database configuration is not supported in a cluster. In this situation, the event service in the cluster is disabled by default.
    • The deployed event service application target list is modified to include the new cluster.
  2. Optional: If the existing server was configured with the default Derby database, you must configure a new event database for the cluster and then enable the event service:
    1. On the deployment manager system, run the database configuration administrative command. Specify the cluster name using the clusterName parameter. This command generates the database configuration script.
    2. Copy the generated database configuration script to the database system.
    3. Run the database configuration script on the database system to create the event database.
    4. On the deployment manager system, run the enableEventService command to enable the event service. Use the clusterName parameter to specify the name of the cluster.
