Setting up IBM Health Checker for z/OS

The IBM Health Checker for z/OS framework provides a structure for checks to gather system information and mechanisms to report their findings. The checks compare the system environment and parameters to established settings to uncover potential problems. When z/OS® IPLs, it automatically starts IBM® Health Checker for z/OS, but for optimal use, you'll want to do the set-up steps described in this chapter.

Checks are provided separately from the IBM Health Checker for z/OS framework (see Obtain checks for IBM Health Checker for z/OS for more information on obtaining checks) and individual checks should be assessed for their relevance to your installation. You can override parameters for some checks, and you can override values or deactivate any individual check. See Managing checks.

Note that all the setup steps in Steps for optimizing IBM Health Checker for z/OS for IBM Health Checker for z/OS are the same no matter what types of checks you run, whether local, remote, or REXX. This includes security definitions. Any check-specific setup steps required are documented with the check description in IBM Health Checker for z/OS checks.
