Use this topic to manage the nodes in your node groups
by viewing, adding or deleting the nodes in a node group.

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.
