Preparing the system for testing

This list shows you what you need to consider when preparing the system for debugging.

  1. Make sure that EDF is available in your system, by including group DFHEDF in the list you specify in the GRPLIST system initialization
  2. Set up appropriate tracing options for your application. For details about setting up tracing options, see Using traces in problem determination .
  3. 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 .
  4. 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.
  5. Contact your system programmer for information about SDUMP data sets available on your system and access to JCL for processing them.
  6. 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.
  7. Generate statistics. For more information about using statistics, see Introduction to CICS statistics.
