SDUMP recovery fault recording data sets
When an SDUMP is requested, it is generated by the DUMPSRV address space with a naming convention that is determined by DUMPSRV. Normally most users on the system, except for the systems programmers, are restricted by UACC(NONE) to these SDUMPs. To be able to request an SDUMP, Fault Analyzer must use authorized state, which it obtains from its internal SVC process.
Fault Analyzer only uses SDUMP in the recovery fault recording process if the user ID under which the abend occurred was granted XFACILIT access using the following XFACILIT resource class setup.
