System dump formatting program
The system dump formatting program is for use on z/OS® system dump (SYS1.DUMP) data sets that record system dumps requested by CICS® through the z/OS SDUMP macro. The program is invoked by the interactive problem control system (IPCS). You can use IPCS either interactively or from a z/OS batch job. The CICS-supplied sample system dump formatting program is named DFHPDnnn, where nnn is a release identifier. For example, its name is DFHPD760 in CICS TS 6.3.
Dump utilities (DFHDUnnn and DFHPDnnn) lists the name of the CICS-supplied dump formatting program by release.
For further information about the system dump formatting programs, about using IPCS to format and analyze CICS dumps, and about the dump exit parameters available, see Dump utilities (DFHDUnnn and DFHPDnnn).
Design overview
The system dump formatting program produces a formatted listing of CICS control blocks grouped within functional area. CICS dump exit parameters can be specified on the IPCS VERBEXIT subcommand to indicate whether the control block output is to be produced or suppressed for each functional (component) area. Summary reports are available for certain of the functional areas, and the dump exit parameters can also indicate whether these are to be produced or suppressed.

Exits
Global user exit points are not applicable to offline utilities.
Trace
Trace points are not applicable to offline utilities. However, the output obtained and any messages issued by the system dump formatting program might provide clues to problems associated with corrupted data.
