At DFSMShsm startup, DFSMShsm reads the ARCCMDxx parameter library (PARMLIB) member that is pointed to by the DFSMShsm startup procedure or is found in the MVS™ concatenated PARMLIB data sets.

An ARCCMDxx member consisting of DFSMShsm commands that define your site’s DFSMShsm processing environment must exist in a PARMLIB data set. (The PARMLIB containing the ARCCMDxx member may be defined in the startup procedure.) An example of the ARCCMDxx member can be seen starting at Starter set example.
