A core group is a component of the high availability manager function. A default core group, called DefaultCoreGroup, is created for each cell in the WebSphere Application Server environment. A core group can contain standalone servers, cluster members, node agents and the deployment manager. A core group must contain at least one node agent or the deployment manager.
