Viewing, adding, and deleting node group members
Use this topic to manage the nodes in your node groups by viewing, adding or deleting the nodes in a node group.
Before you begin
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 IBM i 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.
