Subsystem target volume

The libraries on this volume consist of the subsystem product sets (CICS®, DB2®, IMS™, NCP, or WebSphere® Application Server). There can be any number of this type of volume on a system.

The recommended types of data sets for this volume are:

Subsystem target libraries.
Alternate subsystem SMP/E global CSI, if applicable.
SMP/E target CSI
SMP/E target data sets: SMPLTS, SMPMTS, SMPSTS, SMPSCDS
User catalog for the SMP/E global and target CSIs. Unless a data set must be in the master catalog, all the subsystem target libraries should be cataloged in the user catalog.

Reasons to put these data sets on this volume are:

To keep these data sets off volumes that are overlaid by a system replacement.
To keep the subsystem together on the same volume.
To facilitate data set sharing between systems and maintain data sets in one place.

A subsystem product set might need to be serviced before it can be used with a new z/OS® system. However, service updates usually can be made before the z/OS migration.
