Querydub will only tell you if the dub MIGHT work or fail but it doesn't tell you why.
I use the initusp call to actually dub the environment which will return a reason if it fails, you can tell exactly why it wont work (or at least get closer than querydub) could be that there is an omvs segment but it is not fully defined... Some reasons are 1. no omvs segment 2. no uid in the omvs segment 3. no gid in the omvs segment See the "security server RACF callable services" Eric Spencer Neon Enterprise Software Inc > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On > Behalf Of Don Poitras > Sent: Friday, December 15, 2006 2:21 PM > To: IBM-MAIN@BAMA.UA.EDU > Subject: Re: Checking For OMVS Segment From Assembler > > Harry Goldschmitt wrote: > > > > I recently had a major bug at a site with a C++ application running > > in MVS batch.
