The dump code options you can specify

You can specify what dump action is to be taken by CICS for each individual dump code, either by using a CEMT transaction or by using a system programming command. The options you can specify differ slightly, depending on whether you are defining the action for a transaction dump code or for a system dump code.

Notes:
  1. Only a transaction dump code can cause both a transaction dump and a system dump to be taken.
  2. If a severe error is detected, the system can terminate CICS even if you specify that CICS is not to be terminated.
  3. Values of 0-998 for "maximum times dump code action can be taken" are literal, but a value of 999 (the default) means there is no limit.
  4. You cannot suppress CICS kernel domain dumps.

All the options you specify are recorded in the appropriate dump table, and written in the CICS global catalog. Any dump table entries you have changed or created during a CICS run are preserved when CICS is subsequently shut down. They are available during the next run unless CICS is cold started, when they are deleted from the global catalog.

The only circumstances in which dump table additions and changes are lost are:

Specifying the areas you want written to a transaction dump

When you use the EXEC CICS DUMP TRANSACTION command to get a transaction dump, you can specify which areas of storage are to be dumped. You cannot specify in the dump table which areas are to be written to the transaction dump for particular transaction dump codes. You always get a complete transaction dump whenever a transaction abend occurs, if the dump code requires a transaction dump to be taken.
