Managing IBM JES2 in MVS 3.8- M41

[@kellingc]

When I was an operator at a hospital, we moverd from running 5 machines under DOS/VSE and VTAM to several partitions of a Z360 running MVS. We had Computer Associates to interface with TSO. CA7 (CASCHED) created the schedule of batch jobs, CA11 (CADISPATCH) handled the output. Every Sunday Morning at 2:00, we did a shutdown and IPL. I got so I knew what jobs and subsystems could come up at what time. I'd normally have us shutdown, have the SE start the IPL, and have CICS up for the nursing units abd ER in 20 minutes. It also helped we were replacing what DASDs we could with RAMACS.

Nice . Thank you

Very useful video, thank you. I understood the process of creating another spool space on another volume but unclear on how to append that area to the default spool on HASP03. Of course, my preference would be to define the spool on a larger DASD and use it instead. I’m also glad to see you encounter some problems as I now know how to address them. As you say, programmers also need to become systems users and take care of the OS too.

Its been a long time. Thanks for your interesting JES2 mainframe video.

+Rocky Yap thanks a lot. Yes, I was traveling.

Hello, In 50:12 you mentioned that it should allocate 20 cylidners and allocated 300 and you need to figure it out but the info screen displays the tracks, not cylinders and 20 cylinder is 300 tracks (20*15=300). When you've submitted 726 job it shows 300 tracks also so in both cases were 20 cylinders. No need to figure it out :)

You came accross in your video with a very annoying bug in Vista TN v.2.0 in which the copy/paste feature crashes the program. I talked about that with Tom Brennan some time ago and he is working around it in a newer version. In the meantime, he sent me his development version which has all the features of v.2.0 without that annoying bug with copy/paste. Hope that helps. Thanks for your great videos, by the way. I always learn something new in each of them.

[@moshixmainframechannel]

Thank you. Tom did mention that to me and he did give me a new dev version. If I lost it 😀

Music is great, I love Purple motion :-)

How can you view the SYSLOG? I can see SYSLOG files on the spool but they all show zero records.

[@moshixmainframechannel]

From the console it from IMON option OT

I find it useful for deleting datasets step in jobs to use IDCAMS DELETE and SET MAXCC. This way step will attempt to delete dataset and if dataset does not exist SET MAXCC will set step COND CODE to 0. If dataset do exist it will be deleted, and step COND CODE will again be 0. So job will not stop executing after delete step if dataset does not exist. Very useful for dss dumps or IFASMFDP jobs. //DELETE EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //SYSIN DD * DELETE dataset SET MAXCC=0 /*

[@moshixmainframechannel]

Daniel, yes very much true. I use IDCAMS and SET MAXCC in my VSAM video here: kzbin.info/www/bejne/mGXIoqKvpct5Z6M

[@macieksoft]

Running JES2 like boss. Oh well, if boss knew how to run it he wouldn't need you as a mainframe operator ;-)

[@MrJaenicke]

on 1:04:10 you changed the msgclass=K BUT in SYSOUT=A (from the proc) not SYSOUT=*, * means use msgclass value in jobcard

[@moshixmainframechannel]

Ok

[@EdouardTavinor]

hi :) i've just discovered F2 and F9 :) it's rather like gnu-screen or tmux :)

[@Stosszahlansatz]

The job output in class K did not print right away because class K is a hold class :-). You needed to release the held job output with the $O command.

[@moshixmainframechannel]

Thanks! Yes I should have checked the JES2PARM definitions. Thanks a lot

[@martygenska8117]

Check your JES2PARMS; those classes are probably being HELD.

[@MrJaenicke]

great info, thanks, another question, I try to run the sample job to change the pw for a user but afterwards the user can not logon any more //CHGPWD EXEC PGM=IKJEFT01 //SYSUADS DD DISP=SHR,DSN=SYS1.UADS //BRODCAST DD DISP=SHR,DSN=SYS1.BRODCAST //SYSTSPRT DD SYSOUT=* //SYSTSIN DD * PROFILE NOPREFIX ACCOUNT CHANGE (HERC02) DATA(JAGUAR) END

[@moshixmainframechannel]

What’s the job output ?

[@MrJaenicke]

@@moshixmainframechannel I am running this SYS2.JCLLIB(CHGPWD) and get PROFILE NOPREFIX ACCOUNT CHANGE (HERC02) DATA(JAGUAR) IKJ56575I USERID HERC02 NOT FOUND AS SPECIFIED BY NODELIST END END

[@MrJaenicke]

ok, thanks, fixed

[@zareenremendies]

Thanks so much for such an inspiring video

[@danhale8079]

Great video, but the music gets tiresome after a while. But keep up the good work.

[@moshixmainframechannel]

Thanks
