How to check number of open handles on a particular queue manager ?

Note: MAXHANDS displays default MAX number of open handlers.

MAXHANDs specifies the maximum number of handles that A TASK can have at the same time (so it is not a maximum of handles that a queuemanager can deal with).

afaik there is no display for that. you could use a display qstatus type(handle) and then look for the application and iproc / oproc counters to get a value, but i do not belive that this is accurate. but it may give you an approx. value.

Great for MQ6.0 and above, but not for us poor suckers forced into using 5.3 and below (VERY long story, don't ask)

BUT, when we were having problems of applications going berserk and consuming all resources I asked IBM for some back door method, and got rewarded with this:

I am an optomist at heart. When a poster doesn't specify version, I assume that they are running the latest.

that utility that is in described in the link works for W2K as well. You get a complete dump of every connection and handle, including incoming channels. I'm working on a perl script to summarise the info nicely into a page or so (depending on load on the queue manager of course) but it's bottom of my list at the moment.

BUT I've found the output useful when you use tools like grep and wc to find out what is happening.

You asked for a back-door method, and that is what you got!
I don't expect you thought it would be quite as back-door, or quite as technical, as that.

This is why the new runmqsc commands were supplied at v6.0, so your only real recourse is to upgrade to take advantage of them.

If it was up to me, I would, but in this shop SAP XI is supposed to take over so no changes or development of the existing solution is countenanced.

P.S. I actually found this routine quite useful and will enjoy writing a PERL program to summarize it - it's got some very handy info all in one particular place- I've used in on two occasions in Production already to pin-point where the offender was.....
