Defining the DFSMShsm MVS environment

You define the MVS™ environment to DFSMShsm when you specify:

The job entry subsystem
The amount of common service area storage
The sizes of cell pools
Operator intervention in DFSMShsm automatic operation
Data set serialization
Swap capability of DFSMShsm’s address space
Maximum secondary address space

Each of the preceding tasks relates to a SETSYS command in the ARCCMDxx member.

Figure 1 is an example of the commands that define an MVS environment:
