The CICS® VSAM workload (DSW) was run in a multiple address space environment with, and without, CICS IA interdependency data collection running.
Table 1 shows figures for the combined AOR regions.
Transactions per second | CPU per transaction with IA stopped | CPU per transaction with IA running | Delta per transaction | Delta per file control call |
---|---|---|---|---|
538 | 0.64ms | 0.71ms | 0.07ms | 0.007ms |
723 | 0.65ms | 0.72ms | 0.07ms | 0.007ms |
1081 | 0.65ms | 0.73ms | 0.08ms | 0.008ms |
1639 | 0.66ms | 0.73ms | 0.07ms | 0.007ms |
With an average of 12.76 file control calls for tasks that issue file control calls, and with 75% of tasks issuing file control calls, the number of file control calls per task is 9.57 (12.76*75/100). This figure is divided into the "Delta per transaction" to obtain the "Delta per file control call" value.
This 7 microsecond value matches the value obtained from the component testing for file control interdependency data collection, described earlier.
