Hi friends
I 'm confused about the content of the DUMP DATASET and TRACE DATASET.
How I can related to them together?
What is deference between these contents?
And what is the common between themes?
Thanks.

Dumps and traces are both used in debugging problems. However, their basic nature is very different -- a dump is a point-in-time snapshot of the system (hopefully at or near the time of an ABEND) whereas a trace is a time-based listing of commands (instructions) issued. Many dumps include some trace information since it can be helpful to know what was happening before the dump occurred.

I read this in one of the CICS manuals, and don't understand the distinction:

Quote:
Formatting and interpreting trace entries
The internal trace table can be formatted in one of two ways:
1-From a CICSĀ® system dump, using the CICS print dump exit, DFHPD710.
2-From a transaction dump, using the CICS dump utility program, DFHDU710.


Quote'd. Also, please don't use sizes and colours to draw attention to a particular point you want to make. Oh, wait..

The difference is that a CICS System Dump is a dump of the CIC address space whereas a transaction dump is a dump of just the storage related to a CICS transaction - a much smaller beast.
