HEALTHY Status
z/OS Health Checker features productivity and ease-of-use enhancements

I

BM Health Checker for z/OS* provides an infrastructure to help simplify
and automate the identification of potential configuration problems before
they impact system availability. It compares active z/OS and sysplex
settings to those suggested by IBM or defined by your installation, reporting on
deviations from IBM recommended practices, proximity to critical thresholds,
recommended and required migration actions, etc., while also providing
suggested remedial actions and additional references.
It primarily consists of two parts:
George Ng
is a senior certified
IT managing
consultant for
IBM Systems Lab
Services at IBM
Poughkeepsie.
Ulrich Thiemann
is an advisory
software engineer
at IBM Rochester,
a member of
the z/OS Core
Development team
and technical
lead for z/OS
Health Checker.

1. The framework or general
interface that allows you to
run and manage checks. It's
shipped as part of the z/OS
Base Control Program.
2. The individual checks themselves. These are primarily
IBM-supplied programs-over
200 to date-that examine
specific settings or values for
potential problems but can
also be provided by ISVs or
written by users.

z/OS Enhancements
A product since V1.7, the IBM
Health Checker for z/OS has
been part of the base system
for many years. Many notable
enhancements (e.g., productivity and ease-of-use improvements, additional checks that
cover new problem areas) have
been delivered in the past few
z/OS releases.
What follows is a look at some
of these recent enhancements.
32 // JANUARY/FEBRUARY 2017 ibmsystemsmag.com

The full descriptions of all
enhancements can be found
in "More Resources" on page 37.
Autostart
As of z/OS V2.1, procedure
HZSPROC-the back end of the
Health Checker framework-is
automatically started at the time
of IPL. Not required, but provided for compatibility reasons,
is a HZSPROC system parameter
in the IEASYSxx PARMLIB member to allow users to:
ĀÃ 2YHUULGHÃWKHÃGHIDXOWÃSURFHdure name HZSPROC
ĀÃ 2SWÃRXWÃRIÃDXWRVWDUWÃWRÃKDYHÃ
more control on when and
how HZSPROC starts (e.g.,
via an automation product
or never)
Persistent Data
The Health Checker framework allows persistent data
(i.e., data saved across IPLs) to
be maintained for individual
health checks. Prior read/write

interfaces were only available
as assembler services. In z/OS
V2.2, REXX callable functions
are available to read and write
persistent data, thus providing
consistent, persistent data access
across different check locales.
These functions are:
ĀÃ +=6/3'5')ÃZUDSVÃH[LVWLQJÃ
DVVHPEOHUÃVHUYLFHÃ+=635($'
ĀÃ +=6/3':5)ÃZUDSVÃH[LVWLQJÃ
assembler service HZSPWRIT
Conditional/Filter
Statements in HZSPRMxx
In z/OS V2.2, using the small
programming enhancement (SPE)
in APAR OA49807, a new WHEN
statement allows you to specify
statements conditionally in an
HZSPRMxx PARMLIB member
to be applied depending on the
particular system configuration.
If the conditions specified in the
WHEN statement are met, the
statement or statements within
are applied as appropriate for the
type of statement. This allows
