Read about Nodes groups if you are unfamiliar with them.

About this task

Make the nodes that you organize into a node group 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.

Node group membership must adhere to the following rules:
  • A node in a node group must be a managed node.
  • A managed node must be a member of at least one node group. Initially, all WebSphere Application Server nodes are members of the default node group named DefaultNodeGroup.
  • If the node is on the z/OS platform, the node must be a member of a sysplex node group. The node can also be a member of other node groups that are not sysplex node groups.
  • Nodes on distributed platforms and i5/OS platforms cannot be members of a node group that contains a node on a z/OS platform.
  • Nodes that are in different sysplexes must be members of different node groups. Nodes that are in the same sysplex must belong to the same node group.
