Node group collection

Use this page to manage node groups. A node group is a collection of WAS nodes. A node group defines a boundary for server cluster formation.

Nodes that are organized into a node group should be enough alike in terms of installed software, available resources, and configuration to enable servers on those nodes to host the same applications as part of a server cluster. The deployment manager 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 i5/OS 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 i5/OS 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.
