By default a dump only will be produced if a IMS tools execution ends with a return code equal or greater than 17.
However a dump might be necessary for problem analysis for any failing job execution, even if the return code is less than 17.
If a dump is needed for problem analysis with a failing IMS tool execution which does NOT produce a dump, re-run this job using an additional execution option
ABENDRC=n (where n is equal or less than the return code being issued by the failing job execution).
The dump is written to DD statement SYSUDUMP, which will be dynamically allocated by the IMS tool.
