Hi, Some application or subsystem is creating those groups. I do not know who creates them or their purpose in doing so. One possibility is JES since "Setting Up A Sysplex" suggests that the JES can construct group names based on the node name. The detailed member display output might provide some clues as to who they belong to. But in general the applications will create/join whatever groups they need.
