The dmgr does no validation to guarantee that nodes in a given node group have anything in common.
Node groups are optional and are established at the discretion of the WebSphere administrator. However, a node must be a member of a node group. Initially, all Application Server nodes are members of the default node group. The default node group is DefaultNodeGroup.
A node can be a member of more than one node group.
Nodes on distributed platforms and the IBM i platform cannot be members of a node group that contains a node on a z/OS platform. However, nodes on distributed platforms and nodes on the IBM i platform can be members of the same node group.
To delete a node group, the node group must be empty. The default node group cannot be deleted. From the console...
