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
- 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.
- 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:
- 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.
- Copy the generated database configuration script to
the database system.
- Run the database configuration script on the database
system to create the event database.
- 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.
