Re: LARGEDS and Z11 Mode
I did not have any issues, so I never needed to do this. Anybody have issues restoring jobs offloaded to tape that are z2 mode after going to z11 mode?

Re: LARGEDS and Z11 Mode
Well, we were already at Z11 mode, and post 2.2 you can go to Z22 mode to get the new JES features. One of the pre-req's to get there is CYL_MANAGED=ALLOWED. We had that turned off. Turned it on dynamically in my TECH environment and instantly all of my Roscoe users were unable to view any JES output created after turning it on, and worse yet, turning it back off, the output was still unable to be accessed from Roscoe. CA is still working on fixes. And, as an FYI, CYL_MANAGED=ALLOWED came along in z/OS 1.11. As an aside, our spool is all mod-54's, and could be part of the reason why CA has had a hard time replicating the problem on their end. _ Dave Jousma Manager Mainframe Engineering, Assistant Vice President david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Dazzo, Matt Sent: Wednesday, June 01, 2016 10:11 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: LARGEDS and Z11 Mode Planning for z1.13 to 2.2 upgrade and found that we need to move to jes2 checkpoint mode Z11.
