specifies whether CMF MONITOR collects data for specific SMF fields that contain the high-water marks for HyperPAV LCU
YES
CMF MONITOR collects data for the following SMF fields that contain the high-water marks for HyperPAV LCU:
R783HAIU
R783HCAD
R783HIOQ
R783HAIU is displayed in the HyperPAV MAX USED column of the I/O Queuing Activity report.
This value is the default.
NO
CMF MONITOR does not collect data for the specified SMF fields
This parameter is applicable only for CPM mode and is ignored if specified for the IPM mode. CMF MONITOR does not collect data for the specified SMF fields for SMF 78-3 IOQ records that are produced by the IPM mode.
The MVS collection of high-water marks supports only one monitoring application, which is an MVS design restriction. If you currently have both CMF MONITOR and RMF that are producing SMF 78-3 IOQ records, the high-water marks are incorrect in both CMF and RMF records unless you implement one of the following options:
If you want CMF MONITOR to collect high-water marks, modify RMF options to not write SMF 78-3 IOQ records and, for CMF MONITOR, specify HPVHWM=YES or simply omit this parameter.
If you want RMF to collect high-water marks, specify HPVHWM=NO to cause CMF MONITOR to not collect the high-water mark data. The high-water marks in RMF records can be collected, and those in CMF records are zero.
Only a CMF MONITOR PAS that is started with CXEN=Y can collect the high-water marks in the SMF 78-3 IOQ records that are produced by the CPM mode. CXEN is a parameter on the PAS PROC; the default is Y.
