Considerations for VSAM data sets include the following:

• INCLUDE and EXCLUDE filtering is performed on the cluster names of the data sets.
• If you specify the BY criterion DSORG, MULTI, CATLG, or FSIZE, filtering is done at the cluster level. One exception is the DEFRAG command, that filters at the VSAM component level. If you specify other BY criteria, the data components of the selected clusters are further filtered on those BY criteria by using information from the volume table of contents (VTOC). If a data component is selected, the index component for the cluster is also selected. Again, the one exception is the DEFRAG command, that requires index components to pass all BY criteria.
• DFSMSdss supports the BY criterion EXPDT as it exists in the VTOC only.
• For a physical data set RESTORE, to prevent index components from being restored inadvertently, you must specify the fully qualified name of the cluster.
• For data set print operation, the fully qualified name of the data set to be printed is required. Support is at the component, not the cluster, level.
