CA 1 Health Checker › Parameter Overrides for CA 1 Checks

Parameter Overrides for CA 1 Checks

The IBM Health Checker for z/OS allows the override of selected default parameters by specifying desired defaults on the POLICY statement in the HZSPRMxx member of parmlib. This is useful in changing such values as INTERVAL to a value more appropriate for your installation. Individual checks can also be written to support parameter overrides using the PARM( ) parameter on the POLICY statement. For a complete list of parameters that can be overridden, see Managing Checks in IBM Health Checker for z/OS User's Guide.

These parameters can also be overridden by using the MODIFY command to pass the desired parameters to the IBM Health Checker for z/OS started task.

F hzsproc,UPDATE,CHECK(check_owner,check_name),PARM='chkparm'

Example:

F HZS,UPDATE,CHECK(CA_1,CA1_FREE_DSNB_QUICK_SCAN),

      PARM='SCANLIMIT(1000)'

If a CA 1 check supports the override of a parameter, it is documented in the Parameters Accepted section in each check topic that follows. The default interval and the exception interval are provided in the Description section of each CA 1 check topic.

To run the health check with user-specified parameters instead of the default parameters (even after an IPL), you must define the parameters in the HZSPRMxx member in SYS1.PARMLIB. Specify the parameters within the parm member pointed to by the HZSPROC member in SYS1.PROCLIB.

Example:

You want the following:

• The CA1_FREE_DSNB_QUICK_SCAN member to run with a SCANLIMIT parameter of 5000 rather than the default of 1000
• A DEQLIMIT of 500 rather than the default of 100

You update the HZSPRMxx member in SYS1.PARMLIB:

ADDREPLACE,POLICY=MORE,STATEMENTNAME=DSNB,UPDATE,
CHECK(CA_1,CA1_FREE_DSNB_QUICK_SCAN),
PARM('SCANLIMIT(5000),DEQLIMIT(500)'),
DATE(20131125),REASON('CHANGE DEFAULT PARMS')
ACTIVATE,POLICY(MORE)
