The CICDTR query generates daily charts showing overall transaction counts and response time metrics for individual CICS regions. A separate chart is produced for each z/OS SYSID and CICS region combination. The charts show the total transaction count for each hour using a stacked vertical bar—where the overall transaction count is broken down into two bar segments. One segment shows the transaction count that met a user-specified elapsed time goal using a blue bar (default one second), and the other segment shows the transaction count that missed the goal using a red bar.
In addition, the chart uses a horizontal line to show the percentage of transactions, per hour, that met the response time goal (green line). A user-specified desired percentage (default 95 percent) is plotted (blue line) to allow for easy visualization of the actual percentage of transactions, compared to the desired percentage of transactions, that met the response time goal.
The example shows the chart generated for a CICS region "MROA" running on a z/OS system "ASYS". This chart was produced from a CA MICS database built from CICS transaction records where we had not collected the associated RMF data. The Central Processing Complex ID (CPCID) was not available and set to "UNKNOWN." At a normal customer installation, one of the query steps examines the CA MICS RMF component HARCPU file to determine the CPCID for each z/OS system (SYSID) where the CICS regions executed. The CPCID is assigned a value like "2097-712-Serial AE000’.
The chart shows that transaction volume begins picking up at around 8:00 AM, peaks between noon and 3:00 PM, and then begins tapering off over the rest of the day. Close to 100 percent of the transactions, each hour, met the response time goal of completing in one second or less.
The second line of the title shows the response time target—and must be manually updated in the query output view definition if the response time target is changed from the default value of one (1) second.
