Dumps

A formatted system dump contains (depending on the options specified on the TR keyword):

System dumps requested by the trace domain fall into two categories:

Dump code TRnnnn
These dump codes are preceded by a console message, DFHTRnnnn. See the CICS® Messages and Codes manual for details.
Dump code KERNDUMP
At many points in its processing, the trace domain cannot issue domain calls because they would lead to further trace calls and possible recursion of the error. In these circumstances, the trace domain uses MVS™ WTO to write a console message and the kernel dump function to take a system dump. All such dumps have dump code KERNDUMP. The message numbers for which this occurs are DFHTR0105, DFHTR0114, DFHTR0115, and DFHTR0116. See the CICS Messages and Codes manual for more details.
