Thanks, Lizette! I am aware of those lists, and you are right in saying that I should also post my question there.
Content-wise, I still do see the issue "somehow somewhere in-between" MVS and JES. I'm still not quite sure where to start looking and searching ... Anyway, thanks a lot. Further ideas are always welcome.

If you would like to join, go to these URLs JES2 http://listserv.vt.edu/cgi-bin/wa?A0=jes2-l JES3 http://www.listserv.uga.edu/archives/jes3-l.html The biggest difference I see is that JES3 needs to know it owns resources before it will let things run. JES2 does not. That may be a consideration in trying to run JES3 under JES2 Lizette > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] > On Behalf Of Henn, Karl > Sent: Tuesday, April 21, 2015 3:29 AM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: JES2 as primary with JES3 as a secondary > > Hello JES experts, > > My practical experience with JES3 is near zero, or even <below> zero. > > The software we develop rarely ever has to take into consideration the > differences between JES2 and JES3.
