Dump utilities (DFHDU700 and DFHPD700)

CICS® produces two types of dump: transaction dumps that CICS writes to CICS transaction dump data sets; and MVS™ system dumps (SVC dumps) via the MVS SDUMP macro.

CICS provides two utility programs to help you analyze these dumps:
  • The transaction dump utility program, DFHDU700, for processing CICS transaction dump, as described in this section.
  • The dump exit, DFHPD700, that is invoked from the interactive problem control system (IPCS) for processing either MVS SDUMP dumps that CICS takes, or CICS jobs in SVC dumps that are taken by the MVS dump command. You can use IPCS either interactively or from an MVS batch job. For more information about using IPCS, see Using IPCS to format and analyze CICS dumps: Overview.
    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.)

For information about the CICS dump component keywords, and the levels that you can specify for each of them, see
