Abstract for IBM Health Checker for z/OS

Purpose of this document:

This document presents the information you need to install, use, and develop checks for IBM® Health Checker for z/OS®. IBM Health Checker for z/OS is a component of MVS™ that identifies potential problems before they impact your availability or, in worst cases, cause outages. It checks the current active z/OS and sysplex settings and definitions for a system and compares the values to those suggested by IBM or defined by you.
