Language Environment® invoked IEATDUMP to dynamically allocate a dump data set. However, the allocation was not successful. Return and reason are returned by the IEATDUMP system service or by RACF®. IEATDUMP or RACF might issue other messages to the console or SYSLOG. See message CEE3798I for the name of the data set.
No data set is allocated, no dump is created.
See z/OS MVS Programming: Assembler Services Reference IAR-XCT for information about IEATDUMP return and reason codes.
