Once you have created one or more HZSPRMxx members, IBM® recommends that you define them for use by IBM Health Checker for z/OS® when it starts automatically at IPL time
by doing the following:
- Specify the desired HZSPRMxx suffixes on the HZS system parameter
in the IEASYSxx parmlib member as follows:
HZS={xx|(xx,...,zz)}
- In your hzsproc procedure, default to or define HZSPRM=PREV to
specify that IBM Health Checker
for z/OS use the same HZSPRMxx
parmlib members as it did for the previous instance of IBM Health Checker for z/OS:
//HZSPROC PROC HZSPRM='PREV'
//HZSSTEP EXEC PGM=HZSINIT,REGION=0K,TIME=NOLIMIT,
// PARM='SET PARMLIB=&HZSPRM'
//*HZSPDATA DD DSN=SYS1.&SYSNAME..HZSPDATA,DISP=OLD
// PEND
// EXEC HZSPROC
IBM recommends
specifying 'HZSPRM=PREV' to make occasional manual
restarts (after applying service, for example) easy and consistent.
Having explained the recommendation, we show the full list of possible
HZSPRM parameter values for your
hzsproc procedure
below:
- HZSPRM='PREV'
- Specifies that your hzsproc procedure use the
HZSPRMxx suffixes, if any, used by the previous instance of IBM Health Checker for z/OS within the current IPL. HZSPRM='PREV' is
used as the default in the standard HZSPROC procedure.
HZSPRM='PREV'behaves
like HZPRM='SYSPARM'when the system encounters it at initial IPL time
(the first use of the hzsproc), because there is
no previous instance of IBM Health
Checker for z/OS to use at
that time.
- HZSPRM='SYSPARM'
- Specifies that your hzsproc procedure use the
HZSPRMxx suffixes specified on the HZS system parameter in IEASYSxx.
- HZSPRM='NONE'
- Specifies that the hzsproc use no HZSPRMxx
parmlib members
- HZSPRM={'xx|(xx,...,zz)'}
- Specify the specific suffixes for the HZSPRMxx parmlib member
or members that you wish the hzsproc procedure
to use.
Note: The HZSPRMxx suffixes you specify, explicitly
or implicitly, in the HZSPRM parameter of your hzsproc procedure
override any suffixes defined in the HZS system parameter in IEASYSxx.
If you should happen to leave a manual START
HZSPROC,HZSPRM= command (in COMMNDxx, for example), the HZSPRMxx
parmlib members activated by the IBM Health
Checker for z/OS automatic
startup will still win out. Any subsequent manual START HZSPROC is
ignored and rejected, as long as the current Health Instance has not
been stopped.
