Creating ISMF data set lists

With ISMF, you can create and use data set lists that are groups of data sets that match user-defined selection criteria. Depending on the selection criteria that you enter, these lists can contain hundreds of data set names or only a few.

For more detailed information about ISMF, see z/OS® DFSMS: Using the Interactive Storage Management Facility.

To create an ISMF data set list, select option 1, Data Set, from the "ISMF PRIMARY OPTION MENU":

 To further limit the Generated List, Specify a single value or list of values    
 in any of the following:

     Entry Type . . . . . . . . EQ      CLUSTER                                (5)
      .                                                                           
      .                                                                           

Requirement: Always enter 2, Catalog in the Specify Source of the new list field. CICS® VR creates a recovery job for a VSAM sphere based on its base cluster name. Base cluster names can be retrieved only from the catalog.

The ISMF "DATA SET SELECTION ENTRY PANEL" with sample criteria entered in this example, produced the ISMF data set list shown in the ISMF "DATA SET LIST" panel. The following list explains the entered criteria:
  1. Enter option 2, Catalog in the Select Source of Generated List field on line (1) to create a new ISMF data set list.
  2. Enter 'EXMPHLQ.**' in the Data Set Name field on line (2) to produce a list of data sets with a first lever qualifier of 'EXMPHLQ'.
  3. Enter option 2, Catalog in the Specify Source of the New List field on line (3) so that CICS VR can retrieve the base cluster name for the VSAM spheres selected for the list of data sets. IOption 2, Catalog is required.
  4. Enter TSTVOL in the Volume Serial Number field on line (4) so that data sets that reside only on TSTVOL are in the data set list.
  5. Enter EQ CLUSTER in the Entry Type field on line (5) so that only VSAM base clusters that meet the other selection criteria are included in the data set list.
  6. After you enter this data, press Enter and ISMF creates a data set list as shown in the ISMF "DATA SET LIST" panel.

Result: If you enter the same criteria specified in the preceding steps and press Enter, an ISMF data set list similar to the one shown in ISMF "DATA SET LIST" panel is displayed.
