Language Environment provides three TERMTHDACT suboptions (UADUMP, UATRACE, and UAONLY) to produce different types of Language Environment dumps.
TERMTHDACT(UADUMP) causes Language Environment to produce a Language Environment formatted dump plus a system dump. With this setting, the Language Environment dump includes a traceback and a dump of the thread/enclave/process level storage and control blocks.
TERMTHDACT(UATRACE) causes Language Environment to generate a message indicating the cause of the termination, a trace of the active routines on the activation stack, and a U4039 abend which allows a system dump of the user address space to be generated.
TERMTHDACT(UAONLY) causes Language Environment to generate a U4039 abend which allows a system dump of the user address space to be generated. Under non-CICS, if the appropriate DD statement is used, you will get a system dump of your user address space. Under CICS, you will get a CICS transaction dump.
TERMTHDACT(UAIMM) causes Language Environment to generate a U4039 abend which allows a system dump of the user address space to be generated. Under non-CICS, if the appropriate DD statement is used, you will get a system dump of your user address space.
