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.
