Navigate Servers >> Clusters >> WebSphere application server clusters
Click New >> Enter the “Cluster name” and click Next
Enter the Cluster member name and select the node where you want to create
You have the option to create the member using an application server template, using an existing JVM as a template, convert existing JVM as a cluster member or create an empty cluster.
I’ve chosen to create using a default template, click Next
You can create additional cluster member on next screen if you need, click Next
Review the summary and click Finish
Review and synchronize the configuration changes
This concludes cluster is created and ready to be used. Let’s verify.
Go to WebSphere application servers under “Server Types.”
As you can see, I’ve created tow JVM under “Cluster-1”. By default, they will be stopped state.
To start, you can either start the JVM or whole cluster
If you have multiple JVM’s in a cluster and need to restart all, then you can restart the whole cluster.
Tip: if you need to create JVM in existing cluster then you can do as following.
Go to Servers >> Clusters >> WebSphere application server clusters
Click the Cluster from the list where you want to create a JVM
Click “Cluster members” under Additional Properties
Enter the JVM name >> select the node where you want to get it created and click “Add Member.”
Once added, click Next and then Finish
Don’t forget to review and synchronize the changes.
