Creating reports from summarized data

CMRSUMDN decompresses, processes and creates all records at the F7 level formatted by BBSAMP member CMRQT6E

The summarization batch utility program creates workloads from CICS performance records. You can summarize data collected from multiple CICS regions in intervals from 1 minute to 24 hours. The summary workloads produced by the summarization utility are compatible with the COBOL, SAS, and Performance Reporting Language (PRL) report programs of MainView for CICS.

The following figure illustrates how CMRDETL records are summarized. The summarization utility processes unsummarized records held in a VSAM or sequential data set.

After the records are summarized over the intervals you requested, the newly created summary workloads are stored on VSAM or sequential output data sets. Summary workloads can be created with data obtained from any supported version of CICS.

If you store your summarized records on a VSAM data set, you can view them online with the MainView for CICS HISTORY service. Viewing-summary-records describes the procedure to use the HISTORY service.

Summarizing CMRDETL records gives you several benefits. One benefit is that fewer records are required to produce reports that span long periods of time. For example, producing a monthly report of average daily CPU usage requires only one record per day.

Another benefit of using summarized records is that you can write simpler report programs. Fewer records must be specified for each report interval and the batch program to create the reports generally requires less processing time for each query.

Summarized records are useful for identifying performance trends that become apparent only over long intervals. After you locate CICS problem areas with summarized records, you can use unsummarized data to create reports that give you the detail you need to analyze problems.
