IBM Health Checker for z/OS

IBM Health Checker for z/OS provides a foundation to help simplify and automate the identification of potential configuration problems before they impact system availability. It compares active values and settings to those suggested by IBM or defined by your installation. The IBM Health Checker for z/OS consists of:

  • The framework, which manages functions such as check registration, messaging, scheduling, command processing, logging, and reporting. The framework is provided as an open architecture in support of check writing. The IBM Health Checker for z/OS framework is available as a base function starting with z/OS V1.7.
    IBM Health Checker for z/OS is also available for z/OS V1.4, V1.5, and V1.6 as a z/OS Web download. Make sure that you review the PSP bucket as described in the Web download program directory. There is required service that you must install. This code is part of z/OS V1.4 and V1.5, which have reached end of service. This code is provided without service for those releases.
  • Checks, which evaluate settings and definitions specific to products, elements, or components. Checks are provided separately and are independent of the framework. The architecture of the framework supports checks written by IBM, independent software vendors (ISVs), and users. You can manage checks and define overrides to defaults using the MODIFY command or the HZSPRMxx parmlib member.
    IBM-supplied checks can be integrated with the product, element, or component, or they can be provided as APARs in between z/OS releases. To obtain checks that are provided as APARs, use the Technical help database for mainframe Preventive Service Planning buckets. Once there, scroll down to the Find the bucket by type, category, and release heading, select Function for the Type field, select HCHECKER for the Category field, and click Go.

    There are checks available for multiple z/OS components and elements.

    Note: Many of the checks are also supported on multiple z/OS releases. Review the check APARs for the specific releases supported.
