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 the chapter "Managing Checks" in the IBM Health Checker for z/OS User 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_XCOM, XCOM_ABOVE_16M@stcname),PARM='THRESHOLD(90)'
If a CA XCOM Data Transport check supports the override of a parameter, it is documented in the Parameters Accepted section in each check that follows. The default interval is provided in the Description section for each CA XCOM Data Transport check.
This check monitors the amount of above-the-line storage that has been allocated within the CA XCOM Data Transport address space. The purpose of this check is to be able to provide an alert when above-the-line storage is being depleted beyond the configured threshold. The default interval for this check is every 30 minutes.
Provide sufficient above-the-line storage to the CA XCOM Data Transport region commensurate with the amount of concurrent file transfer activity that the region is expected to process. For guidance in calculating the appropriate virtual storage allocation, see the Storage Usage Worksheet, which is updated and made available for each new release of CA XCOM Data Transport.
This check accepts one parameter, THRESHOLD(nnn). The value specified in THRESHOLD(nnn) is used to determine the percentage of above-the-line storage that can be allocated before a resource shortage exception is recognized. This parameter must be an integer in the range of 1 to 100. The default is THRESHOLD(80).
The current versions of the Storage Usage Worksheets for supported releases of CA XCOM Data Transport are available on the support.ca.com web site.
XCMH503W Available storage above-the-line is less than nnn% of the total amount.
Storage utilization has exceeded nnn% of the amount available to the CA XCOM Data Transport region. Storage shortages within a CA XCOM Data Transport region can cause unpredictable results including, but not limited to, miscellaneous abends, file I/O errors, and network communication errors. The storage shortages could cause failed data transmissions or abnormal termination of the region itself.
