Overview

This report analyzes measured CPU WAIT time. It shows, for each Task (TCB), the percentage of elapsed time the Task was observed to be in a WAIT. Under each task, this information is shown under the following general categories:

APPLCN: Application Code
SYSTEM: System/OS Services
DATAMG: Data Management (DASD) Requests
DB2SQL: SQL Processing
IMSDLI: IMS™ DL/I calls
ADABAS: Adabas requests

In addition, any WAIT time observed at locations for which no load module name could be determined is attributed to a category:

NOSYMB: No Module Name Found

The Task (TCB) name is the object at the top level of the hierarchy for this report, and is the only object visible when the report is first displayed.

A sample report is shown here, as it would appear when it is first displayed:
