Answering you Lizzette via myself if you don't mind, your response came to my work email and not this account :(
you Stated; Think IBM recommendation is for CKPT1 to be in CF and CKPT2 on DASD. That way if either fails, you should be okay. Side Note: Moving the CKPT from CF to DASD or from DASD to another DASD is very easy. We have done ours during the day time. The process is very quick. There is a SHARE presentation from 2004: JES2 Checkpoint Reconfiguration >From the z/OS JES2 Initialization and Tuning Guide SA32-0991-00 In general, to prevent a total loss of the job queue, you should use 2 checkpoints, specify CKPT DUPLEX=ON on all members, and place CKPT2 on a DASD. Thank you so much for the quick answer, I was concerned about moving CKPT2 to DASD and leaving CKPT1 in the CF because we have a DR scheduled this month (local system) and I will be IPL'd both systems on a new CEC and I need to maintain the spool integrity. I'll check the Share presentation you provided, thanks, and thanks for the sanity check with the duplex setting.

I've since read there are somethings I could have tried to recover, but at the time....there was no time.

However, I am curious as to why you had to COLD start. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Carmen Vitullo Sent: Friday, July 28, 2017 6:55 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: JES2 Checkpoint question I've looked and looked at the Init and Tuning REF and Guide and I can't seem to find an answer to my question, I'm hoping someone can provide a sanity check for me. I have a 2 system JES2 MAS both running z/OS 2.1, both checkpoints are currently in a CF with mode=duplex and duplex=on. my issue is both CF's are in the same CEC so a POR of the box for maint last month I lost all my prod spool data and was forced to perform a JES2 cold start. I need to move CKPT1 to DASD and I want to leave CKPT2 in the CF, so my question is can I still run with mode=duplex and duplex=on in that configuration, or do I need to have both CKPT's on DASD. Any insight or recommendations would be very helpful, thank you all ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
