I should have added that we specify DUPLEX=on, which means all updates go to both. _________________________________________________________________ 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

Primary in the CF, secondary on disk. When we recover to our DR systems, we restart JES and it prompts us that the primary is missing, and do we want to start from the secondary. Can't say we have ever noticed a problem. _________________________________________________________________ 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 Jesse 1 Robinson Sent: Tuesday, August 23, 2016 11:05 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Backup JES2 Spool & Restore with Warmstart A question that just occurred to me: Where does your primary checkpoint live? This is pretty ancient history, but in the mid-90s when we first went to parallel sysplex, I tried putting the primary checkpoint in the coupling facility. This meant that the secondary checkpoint was the only one mirrored. Or flashed, if we had had that technology then. The secondary is not updated as often as the primary. Just wondering... . .

No issues with JES2 warm start. They are using DS8870 and z/OS 2.2 but have been doing this for years without problems.
