ASN: Associations Group

This group lists the type (cluster or data, for example) and entry names of the objects associated with the present entry. A cluster or alternate index entry will indicate its associated path entries and data and index (if a key-sequenced data set) entries. Similarly, an index or data entry will indicate its associated cluster or the alternate index of which it is a component.

• An alias entry points to:
  • Its associated non-VSAM data set entry. If the associated entry is a symbolic association (for example, defined with the SYMBOLICRELATE keyword), both the unresolved and resolved values will be listed. The resolved value will be the value resulting from using the symbols defined on the system on which the LISTCAT is run.
  • A user catalog entry. (All alias entries for a non-VSAM data set entry are chained together, as are alias entries for a user catalog entry.)
• An alternate index entry points to:
  • Its associated data and index entries.
  • Its base cluster's cluster entry.
  • Each associated path entry.
• An alternate index's data entry points to:
  • Its associated alternate index entry.
• An alternate index's index entry points to:
  • Its associated alternate index entry.
• A cluster entry points to:
  • Its associated data entry.
  • Each associated path entry.
  • For a key-sequenced cluster, its associated index entry.
  • For a cluster with alternate indexes, each associated alternate index entry.
• A cluster's data entry points to:
  • Its associated cluster entry.
• A cluster's index entry points to:
  • Its associated cluster entry.
• A generation data group base entry points to:
  • Its associated non-VSAM data set entries.
• A non-VSAM data set entry points to:
  • Its associated alias entry.
  • Its associated generation data group (for a G0000V00 non-VSAM).
• A page space entry points to:
  • Its associated data entry. The page space is cataloged as an entry-sequenced cluster with a cluster entry and an associated data entry.
• A path entry that establishes the connection between a base cluster and an alternate index points to:
  • Its associated alternate index entry, and the alternate index's associated data and index entries.
  • The data entry of its associated base cluster.
  • For a key-sequenced base cluster, the index entry of its associated base cluster.
• Path entry that is an alias for a cluster entry points to:
  • Its associated base cluster entry.
  • The data entry of its associated base cluster.
  • For a key-sequenced cluster, the index entry of its associated base cluster.
• A user catalog entry points to:
  • Its associated alias entry.
