Abstract for DFSMS Installation Exits

Purpose of this information :

This document helps you customize DFSMS with installation exit routines and modules that extend or replace IBM-supplied functions at your installation. Storage administrators and system programmers can use this information to centralize customization at their installations. All routines described reside in system libraries; installing them requires authority to update the system library.

This document does not cover all installation exits available in DFSMS. The following table indicates the documents that cover installation exits for the indicated components.

Component	Document
Network File System	z/OS Network File System Guide and Reference z/OS Network File System Guide and Reference
DFSMSrmm	z/OS DFSMSrmm Implementation and Customization Guide
Object Access Method	z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Object Support and z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries

When you install the z/OS system, initialization parameters and SMS options let you tailor the system to your requirements. How you tune z/OS can affect how you customize MVS and DFSMS.
