Is there a way around this? Even with SMS-managed GDGs, where the generation is cataloged at allocation, two jobs that dynamically allocate +1 generations (with GDGNT) will collide.
For example, from two different jobs: (job 1) ./bpxwdyn.rexx "alloc fi(mydd) da('managed.test.gdg(+1)') recfm(v,b) new catalog gdgnt lrecl(1028)" BPXWDYN RC= 0 (0x0) (job 2) ./bpxwdyn.rexx "alloc fi(mydd) da('managed.test.gdg(+1)') recfm(v,b) new catalog gdgnt lrecl(1028)" BPXWDYN RC= 34603008 (0x2100000) IKJ56225I DATA SET MANAGED.TEST.GDG ALREADY IN USE, TRY LATER+ IKJ56225I DATA SET IS ALLOCATED TO ANOTHER JOB OR USER IEFA110I DATA SET CONTENTION ...
