The CICDAT CICS Daily Top 10 Workload Analysis by Region query generates two charts for each SYSID and CICS Region combination. The query uses the DAYS timespan CICS Application Unit Activity file as input, and reports on yesterday’s top ten user-defined CICS Application Unit IDs (CICAPU). The CICAPU data element provides a means to categorize CICS transactions as belonging to specific groups or workloads. The CICCAU file uses CICAPU as a summarization key. The CICDAT query selects the top nn (default top 10) CICAPUs for each CICS region. The top ten are selected based on the highest number of CICS transactions. The top ten CICAPUs are graphically charted using two separate output views.
Note: The CICAPU routine, used in the CA MICS unit used to generate these charts, assigned TRANCODE to CICAPU. The resulting charts are actually showing the top ten transactions rather than the top ten workloads.
The first view shows the overall transaction count for the top ten CICAPUs using vertical bars, and the average CICS transaction response time for each CICAPU with a horizontal line.
The second view shows a response time breakdown for the same top ten workloads, using a stacked bar composed of the percentage of response time spent in dispatch, I/O wait, and other wait time. The total transaction count for each CICAPU is displayed with a horizontal line.
The examples shows the charts generated for a CICS region "MR03" executing on system "ASYS." Merging with data from the HARCPU file was not able to determine the Central Processing Complex (CPC) ID, hence the CPC ID is ‘UNKNOWN.’ The first chart shows that the top two transactions, by transaction count, were "TIVR" with 261,793 transactions and "MVR2" with 185,575 transactions. The average transaction response time was 0.30 seconds for workload "TIVR" and 0.01 seconds for workload "MVR2."
The second chart shows that workload "MVR2" spent 65 percent of the time waiting on I/O, and workload "TIVR" spent 39 percent of the time waiting for non-I/O related delays.
