This section explains the diagnostic aids provided for access method
services (IDCAMS), explains how to find key areas in a dump, and offers
suggestions for isolating different types of problems.
The following major diagnostic aids are provided for access method
services:
- Trace tables, which provide a trace of the flow of control between
modules and within modules.
- Dump points, which provide the facility to dump selected areas
of virtual storage and take a full region dump.
- The TEST option, which you can set to print out the trace tables
or to obtain dumps at selected dump points if access method services
is invoked with a batch job.
- Termination codes and full region dumps, which are produced when
the processor detects an unrecoverable condition.
