ASM_PLPA_COMMON_USAGE

Description:

Looks at the slot usage of the PLPA and Common page data sets. The check generates an exception if the combined usage of both data sets meets or exceeds the warning threshold.

Note:

If the PLPA and Common page data sets are not defined in the system, informational message ILRH0112I is issued to indicate this condition and the check is stopped from running. End of change

Reason for check:

You should prevent full conditions on the PLPA and Common page data sets.

z/OS® releases the check applies to:

z/OS V1R8 and later.

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change

Parameters accepted:

Yes, as follows:

When not using dynamicSEVERITY: THRESHOLD(value),
When using dynamicSEVERITY: THRESHOLD_HIGH(value), THRESHOLD_MED(value), THRESHOLD_LOW(value), THRESHOLD_NONE(value)
Note that when using dynamicSEVERITY, you may specify thresholds for 1 or more of the parameters to identify different thresholds bySEVERITY level. Note that you do not need to specify thresholds for all of the parameters.

The variable for the parameters is as follows:

value: An integer, 0-100 indicating the warning threshold percent. It may optionally be followed by %.

Default: THRESHOLD(80%)

You can use synonyms for these parameters, as follows:

Parameter	Synonyms
THRESHOLD_HIGH	THRESHOLD_HI THRESHOLD_H
THRESHOLD_MED	THRESHOLD_M
THRESHOLD_LOW	THRESHOLD_L
THRESHOLD_NONE	THRESHOLD_NO THRESHOLD_N

Note that when specifying percentages for parameter values, your number for the HIGH cases is smaller than the MED cases, as shown in the following example:

PARM('THRESHOLD_HIGH(90%),THRESHOLD_MED(80%),THRESHOLD_LOW(70%)')
