USERDATASETSERIALIZATION

z/OS DFSMShsm Implementation and Customization Guide
SC23-6869-01

The SETSYS USERDATASETSERIALIZATION option indicates either that other processors do not share volumes or that a product such as GRS or JES3 provides global data set serialization.

If you specify . . . Then . . .
SETSYS USERDATASETSERIALIZATION DFSMShsm serializes data sets processed by volume migration and volume backup by serializing (ENQ) only the data set (and not the volume) during data set processing.
Note: To prevent the possibility of a deadlock occurring with volume reserves, any multivolume, physical sequential, SMS-managed data sets are supported only when the SETSYS USERDATASETSERIALIZATION command has been specified. For more information about these parameters, see z/OS DFSMShsm Storage Administration.
