SYSUDUMP information on z/OS

The z/OS® system can create SYSUDUMPs, which can be used as part of problem determination. This topic shows a sample SYSUDUMP output and gives a reference to the tools for interpreting SYSUDUMPs.

SYSUDUMP dumps provide information useful for debugging batch and TSO application programs. For more information about SYSUDUMP dumps, see the MVS Diagnosis: Tools and Service Aids manual.

Figure 1 shows a sample of the beginning of a SYSUDUMP dump.
