Commentary

Tuesday, January 16, 2001 at 03:15:05 pm    When TNDDISP is logging off a user (as a result of DFB abend) it calls TNDLOGON, which calls TNDPROF, which will occasionally call TNDVTAM, who will occasionally TNDWAIT. This causes a call back into TNDDISP, which is altogether unhealthy. This PTF causes PROF to determine when it is processing on behalf of an abending DFB and skips calls to VTAM (thereby bypassing DISP WAE confusion). This is a PTF.
