No lauphing. I have a moderization project that may prevent CICS apps and other software connected to CICS from being upgraded. However, the TCP stack will need MQ v5.3.1 and MQ needs to connect to CICS4.1.
Anyone else have CICS 4.1 connected to MQ v5.3.1?

I thought one could install multiple versions of MQ in the same LPAR on z/OS?

Jeff, your correct but
I had a typo:
"However, the TCP stack will need MQ v5.3.1 and MQ needs to connect to MQ."
should read
"However, the TCP stack will need MQ v5.3.1 and MQ needs to connect to CICS 4.1". |

Right - my suggestion was to install the v5.3.1 along side whatever version you have working with CICS 4.1, and then go MQ->MQ->CICS.
But maybe you can't *run* more than one version of MQ at the same time in the same LPAR?

Nice idea, but the current version of MQ is 1.2. 
The way MQ communicated with the TCP stack changed between that version and MQ v5+. So the old version of MQ won't fly on the new LPAR either.
The effort is to modernize as much software from the OS up besides.
Now throw in April 2008 for end of support for z/OS v5.3.1 and the timeline for this effort stretches beyond that.
Hopefully, MQ v5.3.1 and/or v6 will hook up to CICS 4.1. I'll be testing that.
Thought I'd see if anyone on the blog who was already in this config. |

I guess I'd have to hope that there isn't...

You may be surprised. No one may admit it though.
I"ve seen commercial accounts where smaller mainframe company's are WAY backleveled in hardware and software. SCAREY! |

I've seen commercial accounts where they've replaced their mainframes with emulated COBOL running on Windows, and filled the holes in their business processes with an almost uncountable number of Access databases.
Backlevel mainframe code? Phah.

I guess you mean smaller companies with mainframes. Yes, this has been going on since mainframes have been around. A lot of the management of these decisions are of the philosophy "if it ain't broke, don't fix it". They do not subscribe to the idea that a vendor will keep on updating a product and drop support on older releases, simply as a ploy to make more money. At least, that is how they see it.

| I installed and ran MQ V5.3.1 with CICS V4.1 a couple of years ago. We were on the verge of migrating to OS/390 2.10 and they pulled the plug at the last moment. |

This philosophy isn't limited to the mainframe environment; although upgrading for the sake of upgrading makes as little sense as not upgrading if there's no reason to upgrade. (I'm trying to think of a more Zen-like phrase to express this.)
It appears to be the case because mainframer skills are getting harder and harder to find; and companies are postponing upgrades pending, uh, whatever they're waiting for.
There are more mainframes now than a year ago. There are more lines of COBOL, more JCL, more UNIX (System Services). Watch as salaries for mainframe skills (continue) to go up. There's a career op. here for those that can say mainframe without a sneer. |

| I rechecked my notes and, I'm embarassed to say, that when we were on the verge of going to OS/390 2.10, CICS was also upgrade to CICS TS 2.2. So, I apologize about my claim regarding CICS V4.1 running with MQ V5.3.1 on MVS. Sorry about that. |
