As someone already mentioned, the JECL is different. It shouldn't be hard to write code to translate.
The other issue is the class structure. JES2 uses an one character class on the JOB card. JES3 used the class on the JOB card or an eight character class on the //*MAIN JECL statement. Ed Jaffe has done some papers on it. ftp://phoenixsoftware.com/pub/demo/JES3_to_JES2_User_Experience.pdf ftp://phoenixsoftware.com/pub/demo/JES3_White_Paper.pdf Dennis Roach, CISSP, PMP IAM Access Administration – Consumer – Senior Analyst 2727 Allen Parkway, Wortham Building 3rd Floor, Houston, TX 77019 Work: 713-831-8799 Cell: 713-591-1059 Email: [email protected] Report information security incidents to: [email protected] and (818) 673-4030 All opinions expressed by me are mine and may not agree with my employer or any person, company, or thing, living or dead, on or near this or any other planet, moon, asteroid, or other spatial object, natural or manufactured, since the beginning of time. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Cheryl Watson Sent: Thursday, January 14, 2016 8:14 PM To: [email protected] Subject: Re: JES3 to JES2 Migration (was JES2 to JES3 Migration) Yes, Lizette - I meant to say JES3 to JES2. Thanks! Has anyone who has done this have an estimate of the amount of time it might take, and the effort? Cheryl -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Lizette Koehler Sent: Thursday, January 14, 2016 9:08 PM To: [email protected] Subject: Re: JES2 to JES3 Migration Cheryl, I am guessing you meant the subject to say JES3 to JES2 migration??? The one challenge I see is the JCL is different between the two environments. JES2 use /* (eg. /*ROUTE) and JES3 uses //* (eg //*MAIN) JES2 has no master JES system, JES3 has a Master. So in JES2 jobs can either run where the JCL is converted or anywhere in the JESMAS. There is also the concept in JES3 that until all resources available, the job will not run. JES2 it can run and wind up waiting on resources. Those are about the differences I can think of off the top of my head.
