Issue/Introduction

The #TSTDC records statistics for a task. Clients may record or query fields in this dsect. If they do, having a detailed understanding of what the fields represent is useful. 

The TSTTIMWT is documented as "WAIT TIME (10**-4 SECONDS)" in the #TSTDS Dsect, which represents the Task Statistics table. What wait time does this field actually represent?

Environment

Release:
Component: IDMS

Resolution

The value in the TSTTIMWT field is the accumulated total of all WAITs for the life of the task execution. It is not a a high water mark (HWM) of the longest amount of time the task waited for a single Wait occurrence. The Inactive Interval & External Wait timers measure the longest single interval that a task has waited for a resource. They check for something completely different than what the TSTTIMWT records, so anything that compares these two values will not be useful.
