IEADMP00 (ABDUMP written to a SYSUDUMP data set)

IEADMP00 contains IBM® defaults and installation parameters for ABDUMP for use when an ABEND dump is written to a SYSUDUMP data set. ABDUMP parameters for a SYSUDUMP data set may be specified as follows:

• The dump request parameter list pointed to by the DUMPOPT keyword of an ABEND macro. (An ABEND dump can also be requested through the CALLRTM and SETRP macros. For details, see z/OS MVS Programming: Authorized Assembler Services Reference ALE-DYN and z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO.) The list can be built by using the list form of the SNAP macro. (For details, see ABEND and SNAP macros in z/OS MVS Programming: Assembler Services Reference ABE-HSP.)
• The initial system dump option specified in IEADMP00. This option is added to the options on the dump request parameter list.
• The system dump options as altered by the CHNGDUMP command. With the CHNGDUMP command, options can be added to or deleted from the system dump options list. The CHNGDUMP command can also cause the dump request parameters to be ignored. (For a description of the CHNGDUMP command, refer to z/OS MVS System Commands.)

During IPL an information message will notify the operator if IEADMP00 is invalid or cannot be found. No prompting of the operator will occur. If the member contains both valid and invalid parameters, an information message will indicate the valid options that were accepted before the error occurred.
