If I have formed a cluster of WAS servers running for a J2EE application and prepared to deployed a EAR files to all servers, do I have to deploy for each server in the cluster using WAS Admin. Console? If not, does Deployment Manager help me for that so that no duplicate work is done?
The purpose of a cluster is for you to deploy an application on it. You can choose a cluster as your target and WAS will deploy the application to each member of the cluster. For more details see my book, link below in my signature
