SVC 046
SVC 046 is a Type 2 SVC issued by the timer supervision routine, TTIMER/STIMERM TEST/CANCEL. This macro returns the remaining time in an interval set by an STIMER call (SVC 047). Optionally, it can cancel the timer.
Hints
It is unusual to see CPU or wait reported to SVC 046, except in on-line regions that process only at timed intervals. CICS uses this SVC for runaway tasks. Every time a task is dispatched, a STIMER is used over and over again.
Use the attribution reports to find the location in the application program that issues the call. Determine if it is necessary to check or cancel the running timer.
