But it does meet his two criteria - manage it like he does his distributed, and not learn to be a systems programmer.
Really, though, at least half of what you are talking about can be managed by a competant mainframe systems programmer with no MQ knowledge, working in conjunction with a competant MQ admin.
At least, that's been my experience - that when I've had to get stuff done on z/OS I could get by with the help of a MF sys prog who hadn't done any MQ.

Specifically, we have a major argument with my MF collegue over the use of MA12 from Wayne Schutz. My common sense told me it must operate just like the included runmqtrm in other platforms, that it should be running all the time, that only one initiation queue is needed per qmgr, and the process definition's applID field should contain sth (job card?) that starts the program.
But right now, app_1 starts the trigger monitor upon sending out a request, when the reply arrives, and a trigger msg put into the initiation queue, the it starts a second application app_2, and shutdown the trigger monitor, the trigger monitor virtually does nothing. This looks a rather strange setting, but it works most of the time. This is certainly not the right way of doing things. But to straighten it out, I have to have certain minimal MF skills related to the tasks. |
So, you're saying that an application puts a message on a triggered queue and then starts MA12 to get the trigger message? That wasn't really the way I had thought it would be used back in 1994. Why do they do it that way?

Quite so, to this day thousands of java programmers wake up screaming in the middle of the night, sobbing and muttering in sheer terror "I dreamt I was coding a JES exit in assembly"

You're probably right, that will be the fastest solution - of course he will have to learn some WMQ z/OS specific knowledge (pagesets etc), but he doesn't have to know how to create the log VSAM files, the MF admin can do that for him. However, if he has the time and money to learn enough MF to be independant, why not? In the end, it's the old time/money paradigm resurfaced...

Good point. You need another hat to know how to do all the DB2 stuff. Actually you problably need a DB2 Admin specific.
If you are going to manage MQSeries on z/OS you MUST be a System Programmer!!!!!!!! No matter how you look at it there is no way around that.
