CICS statistics enhancements

CICS® statistics are enhanced to provide more information that relates to the load, capacity, and performance of the system. This information can aid decisions about vertical and horizontal scalability.

The following sections list the CICS statistics enhancements.

The statistics utility program can handle more CICS regions

The maximum number of CICS regions (APPLIDs) that the statistics utility program, DFHSTUP, can process, is increased from 520 to 2000. This change provides the flexibility to include all CICS regions in a single statistics report.

Changes to statistics data collection defaults

The Data Tables Storage report provides storage totals

The data tables storage reports, produced using the DFH0STAT sample statistics program, now provide storage totals, so that it is easier to monitor how much storage data tables are using. The storage allocated and storage in use for the data table, the entries, and the data is totalled for each data table that is listed in the Data Tables Storage report.

Loader domain statistics provide values for RO TCB

The loader domain global statistics now provide separate values for program load requests that ran on the RO TCB, and for the time taken for these requests. You can use these values to see the proportion of program load operations that ran on open TCBs.

Monitoring domain statistics include address space management

The monitoring domain statistics show whether z/OS® Workload Manager (WLM) manages the CICS address space using region goals, transaction goals, or both.

Monitoring domain statistics include CEC machine type and model number

The monitoring domain statistics show the CEC machine type and CEC model number for the physical hardware environment where the CICS region is running. CEC (central electronics complex) is a commonly used synonym for CPC (central processing complex).

Storage manager statistics include the GUDSA and GSDSA

The storage manager statistics now show data related to the above-the-bar user DSA (GUDSA) and above-the-bar shared DSA (GSDSA), and additional data related to the above-the-bar CICS DSA (GCDSA).

New fields are provided in the Storage above 2 GB report, produced using the DFH0STAT sample statistics program.
