Changes made in z/OS Version 2 Release 1

Exploitation of IBM System z Integrated Information Processors

The RMF Monitor III data gatherer RMFGAT has been entitled to partially run on IBM System z Integrated Information Processors (zIIPs). A new Monitor III gatherer option ZIIPUSE/NOZIIPUSE is introduced to determine whether the RMFGAT address space is eligible for zIIP exploitation.

Statistics about CF structures residing in Storage Class Memory

Storage class memory (SCM) usage and statistics information is available for coupling facilities and structures which are allocated with storage class memory.

RMF provides SCM related information in SMF record type 74-4, as well as in the SCM Structure Summary and the Storage Summary of the Usage Summary section in the Postprocessor Coupling Facility Activity report.

For structures allocated with SCM, the Monitor III Coupling Facility Activity (CFACT) report displays a new Structure Details pop-up window, showing SCM measurements and general structure data.

In addition, new overview conditions are provided for the Postprocessor based on the enhanced SMF record 74-4.

RMF uses the term storage class memory (SCM) as a synonym for Flash Express memory.

Monitoring PCIe function and zEDC activity

A new Postprocessor PCIE Activity Report is available in XML output format and provides measurements about the activity of PCI Express based functions (PCIe functions) and their exploitation of hardware accelerators.

A PCIe function is captured by the report if one of the following hardware feature activities has been measured:

• RDMA (Remote Direct Memory Access) over Converged Enhanced Ethernet
• zEnterprise Data Compression (zEDC) capability using zEDC Express

In addition, RMF provides new overview conditions for the Postprocessor based on a new subtype 9 of SMF record 74.

Support of Group Capacity enhancements and absolute LPAR capacity limits

WLM introduces negative phantom weights for softcapping and uses initial weights to distribute the group capping limit when it becomes necessary to enforce the group limits. RMF adds new fields to SMF record 70-1 and takes the new WLM functionality into account when reporting about capacity groups.

RMF adds support to report on the new absolute LPAR capacity limit that can be defined via the logical partition controls of the Hardware Management Console (HMC). The Postprocessor Partition Data report and the Monitor III CPC Capacity report display whether either Initial Capping or an absolute LPAR capacity limit was active during a reporting interval.

New RMF Postprocessor overview conditions based on SMF record 70-1 can be used for a more detailed analysis of the hardware capping options.

Enhanced Postprocessor Crypto Hardware Activity report

RMF enhances the Postprocessor Crypto Hardware Activity report to provide activity measurements from the Crypto Express4S (CEX4) card configured in one of the three ways:

• Cryptographic CCA coprocessor
• Cryptographic PKCS11 coprocessor
• Cryptographic accelerator

New overview conditions are provided for the Postprocessor, based on the enhanced SMF record 70-2.

Additional Postprocessor reports in XML format

By specifying appropriate ddnames in the job for the Postprocessor output, users can request the following reports in XML output format:

• Cache Subsystem Activity
• Channel Path Activity
• Coupling Facility Activity
• Enqueue Activity
• Hierarchical File System Statistics
• I/O Queuing Activity
• Page Data Set Activity
• PCIE Activity Report
• Shared Device Activity
• Virtual Storage Activity
• XCF Activity

Cross platform monitoring support for Windows

Beyond the support of the AIX and Linux operating systems, RMF XP has been extended to support Windows systems as monitored endpoints. With the Resource Monitoring plug-in for IBM z/OS Management Facility (z/OSMF), performance metrics from Windows systems can be displayed in the same way and together with metrics from other platforms.

SMF Recording Facility for AIX, Linux and Windows performance data

You can now use RMF XP for long-term performance analysis and capacity planning of your AIX, Linux and Windows systems. For this purpose, you can write performance data collected from the monitored endpoints to the new SMF record type 104.

Controlling the invocation of data reduction exit routines

RMF now controls the names of the data reduction exit routines that are invoked by callers of RMF Monitor II Sysplex Data Gathering service ERB2XDGS or Monitor III Sysplex Data Retrieval service ERB3XDRS.

This documentation describes how to apply the required access control. Especially, if an unauthorized application is making use of parameter <exit_name>, a new RACF resource profile of class FACILITY is required.

Enhancement for collecting VSAM RLS activity data

When specifying the VSAMRLS option to gather data for the Monitor III VSAM RLS Activity report, the limit for active data set masks has been raised from 25 to 50.

Monitoring of pageable large pages activity

RMF provides enhanced performance measurements about memory objects and frames in the following reports:

• In the Postprocessor Paging Activity report, the Memory Objects and Frames section has been renamed to Memory Objects and High Virtual Storage Frames and now contains the following enhanced measurements:
  • additional metrics for high virtual common and shared storage frames
  • metrics for 1 MB frames are now reported in more detail
  • number of auxiliary storage slots for frames from virtual common and shared storage backed on DASD.

  In addition, RMF provides new overview conditions for the Postprocessor based on SMF record 71.

• In the Postprocessor Virtual Storage Activity report, the information about 1 MB frames in the Private Area Detail section is now separated into the categories fixed and pageable.
• The Monitor III Storage Memory Objects report now provides measurements for 1 MB frames in more detail at system and address space level.

User controlled location of the RMF Master Gatherer system

The new Monitor III data gatherer option MASTER/NOMASTER is introduced to determine whether an individual system is eligible for master gathering.
