This list shows you what you need to consider when preparing
the system for debugging.
- Make sure that EDF is available in your system, by including group
DFHEDF in the list you specify in the GRPLIST system initialization
- Set up appropriate tracing options for your application. For details
about setting up tracing options, see Using traces in problem determination .
- Make sure that transaction dumping is enabled for all transaction
dump codes, and that system dumping is enabled for all system dump
codes. These are, anyway, the default settings. For information about
setting up dump options, see Using dumps in problem determination .
- Be prepared to print the dumps. Have a DFHDU680 job
stream or procedure ready, and have the CICS® dump
data sets defined in your startup procedure.
- Contact your system programmer for information about SDUMP data
sets available on your system and access to JCL for processing them.
- Enable CICS to detect loops, by setting the ICVR parameter
in the SIT to a number greater than zero. Something between five and
ten seconds (ICVR=5000 to ICVR=10000) is typically a workable value.
- Generate statistics. For more information about using statistics,
see Introduction to CICS statistics.
