LISTSUBSYSDS for Subsystem Sharing Multiple Data Sets

z/OS DFSMS Access Method Services Commands
SC23-6846-01

Figure 1 shows a SHCDS LISTSUBSYSDS for a single subsystem registered with SMSVSAM address space.
  • Subsystem RETLK05A is a commit protocol application (ONLINE) and is currently active (ACTIVE).
  • The subsystem is sharing three data sets and owns retained locks on all three data sets.
  • None of the data sets:
    • Have locks that are not bound to the data set
    • Have forward recovery set in their catalog entries
    • Are in NON-RLS UPDATE PERMITTED state

Because the data sets are not in NON-RLS UPDATE PERMITTED state, none of the data sets were accessed at the time the NON-RLS PERMITTED state was set.
