Purpose of this information
This information helps you implement and customize IBM® z/OS® DFSMShsm. Primarily, this information provides descriptions of DFSMShsm data sets and describes how to create DFSMShsm data sets, procedures, and parameter library members. Global resource serialization, the functional verification procedure, and the DFSMShsm starter sets are also explained. Finally, this information includes special considerations to consider before installing DFSMShsm and describes tuning patches supported by DFSMShsm.
Who should read this information
This information is intended for system programmers and system administrators responsible for implementing a unique DFSMShsm environment. Implementation is the activity of customizing one or more PARMLIB members (ARCSTRxx and ARCCMDxx), startup parameters, and the SETSYS, DEFINE, and ADDVOL commands that define a DFSMShsm environment in one or more address spaces in one or more z/OS images. You should be familiar with the basic concepts of DFSMS described in z/OS DFSMS Introduction. You are presumed to have a background in using TSO and an understanding of z/OS concepts and terms.
