Whenever a CICS system dump is requested,
CICS references a system dump code that corresponds to the event
that caused the dump request to be made.
This is done in order to see what further action should be taken.
More information about this can be found in the
CICS® Problem Determination Guide.
In most cases, system dump codes correspond to a DFH message with
the DFH tag stripped off.
For example, system dump code DM0001 corresponds to message
DFHDM0001 with the DFH tag removed.
For further information, look up the relevant message where
appropriate.
However, there are some exceptions to this format, as shown in
the following list.
