KESCL

This is one of the routines reported in CICS component routines. It implements subroutine call requests.

Any section whose name begins with KE is probably associated with the part of CICS known as the kernel domain. The kernel domain is the 'core' of CICS. The other domains use the kernel to provide services such as linkage and recovery.

Hints

Although execution of CICS application code results in activity in the kernel, there is no direct correspondence between application requests and kernel activity. To reduce activity in these routines, check the Attribution of CPU Usage report to determine which CICS statements are ultimately responsible for the activity. If the activity is not attributed, look in the Transaction CPU Use report. You will probably see the activity in the transaction .CICS (CICS system services) or in CICS system transactions such as CSTP. In these cases, you cannot reduce activity by changing application code.
