ASM_PLPA_COMMON_SIZE

Description:
Checks on the combined size of the PLPA and Common page data sets in relation to the size of CSA/ECSA and PLPA/EPLPA . The check generates an exception if the PLPA and Common page data sets size can not accommodate the percentage (identified by the warning threshold) of the slots required for all CSA/ECSA and PLPA/EPLPA.
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.
Reason for check:
You should define the PLPA and Common page data sets based on the size of CSA/ECSA and PLPA/EPLPA, if known.
z/OS® releases the check applies to:
z/OS V1R8 and later.
User override of IBM values:
Start of changeThe 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 dynamic severity, 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(100%)
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 your number for the HIGH cases is smaller than the MED cases, as shown in the following example: 
PARM('THRESHOLD_HIGH(70%),THRESHOLD_MED(85%),THRESHOLD_LOW(100%)')
