 z/OS RMF Product Information
Performance management for z/OS single system and sysplex environments
| | |
|
If High Performance FICON for System z (zHPF) is implemented on the CPC, RMF displays new zHPF-related measurements in the Monitor II, Monitor III and Postprocessor Channel Path Activity reports.
In addition, RMF provides new overview conditions for the Postprocessor based on SMF record 73.

|
The System Address Space Analysis section of the Postprocessor CPU Activity report is enhanced. The distribution of the In-Ready queue is based on the number of processors being online. With HiperDispatch mode active, the distribution is based on the number of processors online and not parked.

The new Monitor III Storage Memory Objects report (STORM) contains measurements of 64-bit virtual common storage consumption per system and per job. Measurements of the usage of memory objects previously contained in the Monitor III Storage Resource Delays (STORR), Storage Delay Summary (STORS) and Storage Frames (STORF) reports are moved to this new report, which is described by the report data table ERBSTMT3. The measurements for the STORM report are contained in the Monitor III data gatherer tables ERBASIG3 and ERBGEIG3.
The following Postprocessor reports are enhanced to provide 64-bit virtual common storage usage information:
- In the Frame and Slot Counts section of the Paging Activity report, a new Memory Objects and Frames category is added.
- In the Private Area Detail section of the Virtual Storage Activity report, the section containing memory allocation values above 2GB is enhanced with new information about memory objects and 1 MB frames.
In addition, RMF provides new overview conditions for the Postprocessor based on SMF record 71.

RMF periodically checks all types of system resource locks and provides information about lock holders and lock contention in two new Monitor III reports:
- Spin Lock Report
- Suspend Lock Report
|
|
| The Postprocessor Workload Activity report is enhanced to show the CPU times for work units that have been promoted by WLM for reasons of enqueue management and chronic resource management. |
|
|
The Postprocessor Direct Access Device Activity report shows the volume capacity for DASD devices specified by the number of cylinders.
In addition, RMF provides a new overview condition for the Postprocessor based on SMF record 74-1.
|
|
| The Monitor III VSAM RLS Activity reports display the lock set name and the lock structure name associated with the lock set where applicable. |
