I am likely not saying that very well. But I'm thinking that products like CA-11 do this sort of thing for restart (in order to change GDG generation numbers). If this were possible, then perhaps the initiator would do the DEQ at end of job. Perhaps Chris, or another ISV person, would know. > > > On Mon, Apr 20, 2015 at 5:30 PM, Blaicher, Christopher Y. < > [email protected]> wrote: > > > I guess you could do that, assign the initiator TCB to the ENQ, but what > > happens if the job abends before the step you do the DEQ in? > > > > I think this will work - If the purpose is to prevent two similar > > processes, then why not use a common data set and allocate it as > > DISP=(OLD,PASS).
