Dump utilities
CICS® produces two types of dump: transaction dumps
that CICS writes to CICS transaction dump data sets, and z/OS® system dumps
(SVC dumps) through the z/OS SDUMP macro. CICS provides two utility programs to help you analyze these dumps. They are
the CICS transaction dump utility program
(DFHDUnnn) and the CICS dump exit (DFHPDnnn), where
nnn is a release identifier. The dump utility program you use must match the CICS release level of the dump data.
About the dump utilities
The transaction dump utility program, DFHDUnnn is used to process CICS transaction dumps. DFHDUnnn is release dependent. For example, you must use DFHDU760 to process CICS TS beta transaction dumps. Table 1 lists the name of the transaction dump utility program by release.
| Release | Name |
|---|---|
| 6.3 | DFHDU760 |
| 6.2 | DFHDU750 |
| 6.1 | DFHDU740 |
| 5.6 | DFHDU730 |
| 5.5 | DFHDU720 |
The dump exit, DFHPDnnn is invoked from z/OS interactive problem control system (IPCS) for processing either z/OS SDUMP dumps that CICS takes, or CICS jobs in SVC dumps that are taken by the z/OS
DUMP command. You can use IPCS either interactively or from a z/OS batch job. DFHPDnnn is release dependent.
For example, you must use DFHPD760 to
process CICS TS beta system dump data.
Table 2 lists the program name by release.
Note: For the CICS-supplied IPCS dump exit routine to format an SDUMP
successfully, certain SDUMP options must be in force at the time the dump is taken. See the SDUMP
options needed to support the CICS dump exit, listed in Preparing to use z/OS IPCS to format CICS SDUMPs.
