SMS Extended Format Considerations

If the VSE VSAM data set was defined with the EXTRALARGE attribute, CA-FAVER automatically includes DATACLAS(XLARGE) in the DEFINE CLUSTER command given to IDCAMS. Your ACS routines should be coded to expect this and convert the data class name to one that will assign Extended Addressability in your environment.

You can also use *AMS to add the optional DATACLAS parameter during the restore process as shown in the following example:

     CL=PROD.ONL.ARS.ARMST                           -
     *AMS                                            -
        CLUSTER(NAME(PROD.ONL.ARS.ARMST)             -
               VOLUMES()                             -
               DATACLAS(XXL)                         -
        DATA   (NAME(PROD.WEB.ARS.ARMST.DATA))       -
        INDEX  (NAME(PROD.WEB.ARS.ARMST.INDEX))

Another important consideration when restoring files into SMS is the VOLUMES parameter. When restoring files that are SMS controlled, SMS is responsible for volume selection. Unless your SMS environment is set up to handle the VSE volume names, you should nullify the volume list by specifying VOLUMES() as illustrated in this example.
