OS390 good books?

[Ender510]

Can anyone recommend good OS390 reading books? I would like to learn this environment.. my limited exposure has been ispf, ejes, omegamon,k and submitting jobs via JCL. However, i would like to learn about the architecture and how the workload manager works. Thanks!

Not the answer to your question.

Wow. A mainframe guy.

I haven't done any mainframe programming in a year, but that was on an OS370 .
I'm sure you can find a lot of books on Amazon or your local computer book store.
It would depend on what was going to be running on the mainframe I guess on
to which book you'd like to get. Usually 390s run MVS, but they may run VSAM or VM.

Oh yeah! I just remembered a great site for mainframe books:

You should be able to find what you need there.

There's usualy good free stuff over at http://www.redbooks.ibm.com/

Personnaly, I wish that architecture would just die already. Sure its got some amazing features, but their all still tied up by the 'old guard' at IBM and thier wacky proprietary-out-the-wazoo expensive-lease-on-everything mentality. Plus, who needs their extreme reliability if you're gonna load balance them anyway, since their still not perfectly reliable, and there are some functions that just plain requre cycling the machine (you think your new XP box with 2 NIC's boots slow).

And if you've bought into the whole Linux/390 bullcock forget it. My roomate is in the middle of fixing a LinuxVM right now, cursing his head off. There are soooo many little pain in the ass bugs, things that haven't been ported, things that were ported, but some features just up and sh!t themselves. Not to mention that linux doest 'share' well as a VM Guest, seing as it'll eat up all the ram you allow it (frame ram ain't cheap).

Anyway, you asked for information and I gave a ranting opinion. Sorry about that. Check out the redbooks. Also, if you're interested in your own LinuxVM, IBM was running some program where you can sign up and get your own for a month or so, just to futz with it, get comfortable, and mabey do some port-testing.

Oh, plus this, its a link my proffesor gave me (retired VM architect, crazy dude) http://www-1.ibm.com/servers/eserver/zseries/library/

LOL - thanks for all your responses guys.. well, I have more of a curious nature and it's also part of my job as a consultant. my s/w works on most platforms including unix, NT, os390. Also, the s/w will work w/ db2, oracle, informix, sql server, etc. So I need to know all the different OS's as well as the databases as well.. I just started getting into DB2 on OS390 so I been trying to pick this up more and understand the overall architecture and how workload manager works! That's why I been trying to locate some good starter books and that would go over the basics and then over some of the more tuning/performance changes that could be made..

Thanks for the responses everyone and I hope I can locate some good stuff on those sites!

While you're researching, don't forget to read up on z/OS...the latest version of OS/390.

I'm not sure how "new" it is, but we're just now moving the upgrade to our production systems.

You can get most of the IBM Docs for dree to Download from IBM. In addition to the redbooks site check out the Java softcopy reader http://booksrv2.raleigh.ibm.com/homepage/scpyread.html

Some of the products you mentioned are not IBM but CA etc. CA has many of their books on their sites in PDF s etc.

A good thing to learn in an OS/390 env is REXX and Batchpipes. Very powerfull and portable.

z/OS has been out for over a year. Many sites haven't upgraded because it is very hardware dependant as in some CPU's need to be 64 bit able.

The average user won't notice or care.

ROTFL!!

My Dad used manage development of software for OS390 and I used hang out at work sometimes [when I was in college] with the development and QA people...you've never heard such swearing.

But honestly...there are tons of OS390 installs that only pull down for PM's and the last time I remember hearing about a OS390 system getting hacked was...never. Not to say it asn't happened but if development people with 10 years of experience on OS390 were say things like, "Where the hell do I go?!" or, "What the 'front door' am I supposed to do now?!" how well is a hacker going to fare?
