Hi All,

I see a huge 'Open Output Count' value on one of our transmission queue.

I wanted to know is there a threshold value that is set which limits this value.

I see that there is a property at QM level called 'Max Handles'.
But I am not sure whether this value affects the 'Open Output count' value, as i see that the value set for 'Max Handles' is very low then the 'Open Output Count' on the transmission queue.

Regards,
Pats ...

The number of OPPROCS will be consistent with the number of queues that reference it, , e.g. QREMOTE or QCLUSTER,and applications/threads that use those queues.

MAXHANDS(integer) The maximum number of open handles that any one connection can have at the same time.

so this does not affect your open output count. but it does affect e.g. the number of opens an application can perform.

You can display the application details of the open handles on the queue and determine if any look errroneous.

Hi All ... thanks for your inputs ...

One thing i wanted to know is .. will this high value on open output count be a problem. Like will there be a scenario where there is a process wanting the queue and the queue does not have enough handle ...

or is this value controled by any setting on queue or QM level ?

No. It means that n applications have opened a QRemote definitions that refer to the same transmission queue. This means that applications are doing work.

If the message traffic begins to exceed the physical channel bandwidth, you might consider creating a second physical channel to carry additional messages.

...QREMOTE or QCLUSTER...

Although it could probably safely be assumed that Pats21 is not concerned about the S.C.T.Q.
