What's new

This section summarizes the changes or new features in this release:

New short-term and trending data

MainView for z/OS and CMF MONITOR views now display additional short-term and trending data, including:

  • Capacity group activity over time
  • Central electronics complex (CEC) and capacity group usage over time 
  • Information about multiple intervals for capacity groups and CECs
  • MSU utilization, interval MSU per hour, and defined capacity of LPARs
  • Percentage of active and available frames for the system, the system unreferenced interval count (UIC), and paging rates
  • All delay reasons for intervals

In addition, all short-term views now support Single System Image (SSI) mode.

Updated views

Updates to the following views support the enhancement: 

  • LPARGRP and LPARCEC now display information about multiple intervals. The views are no longer summary views. New summary views (LPARGRPZ and LPARCECZ) are available. 
  • LPARGRPS and LPARGRSZ now display the name of the CEC on which an LPAR is running.
  • JDELAYS and JDELAYSZ now display all delay reasons. In addition, the views display the percentage of the interval that was delayed due to the delay reason.
  • Short-term system views (SYSOVERS, SYSOVRSZ, SYSPERFS, and SYSPRFSZ) now display paging rates, the average UIC, and the percentage of central and fixed frames. 

New views

The following new views support the enhancement: 

ViewDescription
LPARGRPZ

Displays information about MSU utilization for capacity groups over one or more intervals

If the information is summarized over more than four hours, the view also displays the 4HRA of capacity groups.

LPARCECZ

Displays information about MSU utilization for CECs over one or more intervals

If the information is summarized over more than four hours, the view also displays the 4HRA of CECs.

LPARGRPS

LPARGRSZ

Display the MSU utilization of capacity groups and their 4HRA during an interval

JDCPUS

JDCPUSZ

JSTORS

JSTORSZ

Display short-term data about jobs, including, page-in rates, and system frame and auxiliary slot usage


SYSFRMS

SYSFRMSZ

SYSFRMIS

SYSFRISZ

Display short-term data about frame usage of system areas (such as CSA and SQA)


Reducing CSA usage for the CMF Extractor

MainView for z/OS and CMF MONITOR are reducing common storage area (CSA) usage for the CMF Extractor by reallocating device sampler data to the 64-bit common memory objects. This change reduces the amount of 31-bit CSA usage by approximately 256 bytes for each device that the device samplers use in Continuous Performance Monitoring (CPM) and Intermittent Performance Monitoring (IPM) modes.

The CMF STATUS command now includes information about memory object storage usage. For more information, see  CMF Extractor Status panel.

Support for data maps

You can use table data maps (TDMs) and data maps with the MainView History Extraction utility (BBM9MD73) to enable third-party products to analyze MainView history data:

  • Data maps describe the fields in the history record entries (REs) for the product.
  • The TDM lists all of the data maps for the product.

The TDM for this product lists the following data maps:

BBDUCE0C  0C   MVMVS*    1   |Wait Use Record Map                  (WAUR)
BBDUCE02  02   MVMVS*    0   |Job Step Record Map                  (JSRE)

BBDUCE51  51   MVMVS     0   |XCF System Record Map                (XSRE)

The TDM member for this product, BBDTDM, is located in the BBACTDEF data set. The data map members are located in the BBMAP data set.

Installation, maintenance, and migration

You install CMF MONITOR by using the Installation System. For information about installation and maintenance, see the Installation System documentation .

Notes

To install a product, always use the most recent version of the Installation System:

  • To determine the most recent version number, see the most recent Installation System release notes .
  • To determine the version number of your current Installation System, see the title line on the Installation System Main Menu.

If you prefer physical installation media instead of downloaded images, request physical media from your BMC sales representative. Contact information is available on the BMC website.

FMID and version information

You can obtain product, solution, and component information (FMIDs, codes, and versions) in the following ways:

  • View the generated installation JCL member $176APLF.
    To search the file, search on the word FORFMID.
  • View one of the following reports:
    • Optimization products, common products, and common components
    • BMC products for IBM DB2
    • BMC products for IBM IMS
    • MainView products

Tip

You can also access these reports anytime from Support Central , as follows:

  1. Go to the Mainframe Installation page on Support Central, or select Mainframe Installation from the Downloads & Products menu.

  2. Click Product codes and FMIDs.

  3. Click one of the listed reports.

Migration considerations 

When you migrate the software, consider the following items:

  • This release requires Version 2.2 or above of the IBM z/OS system.
  • To use the new and updated views, you must recustomize LPARGRP and LPARCEC.
  • Remove any previously specified CSA parameters on the REPORT statement for the CMF Extractor.
    BMC recommends omitting the CSA parameter, or specifying the default values. When you specify the defaults, the product dynamically allocates memory objects, and the Extractor can allocate the 31-bit CSA in small chunks, as required. For more information, see  REPORT.

  • Refresh CMF API modules to version 6.2.

    In support of 64-bit storage, the CMF API modules have changed. The API modules that are typically copied to a linklist data set must be refreshed with the 6.2 version modules. Otherwise, you might not receive the requested data when using CMF MONITOR APIs. For more information, see  CMF MONITOR APIs.
