You can create a new cluster by converting an existing
stand-alone server that is already configured with Common Event Infrastructure.
Before you begin
Before you can convert the existing server, make sure it 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 converting a stand-alone server into the first member of a new
cluster. When the server is converted, the following steps
take place:
- Common Event Infrastructure resources
available at the scope of the server are moved to the new cluster
scope.
Default database: If the existing
server is configured with the default Derby database, the database
resources are not moved to the cluster scope. Instead, these resources
are removed. 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 remove the converted server and add the new cluster.
- Optional: If the converted 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.
