Hi, I am getting below message in my application log when I am trying to connect to Remote Queue Manager from JMS application.
(Thread-95) Failed to open MQ queue , Please check Queue Name
I checked error logs also in Queue manager and found below information
AMQ9513: Maximum number of channels reached.
EXPLANATION:
The maximum number of channels that can be in use simultaneously has been
reached. The number of permitted channels is a configurable parameter in the
queue manager configuration file.
ACTION:
Wait for some of the operating channels to close. Retry the operation when some
channels are available.
----- amqrcsia.c : 1318 -------------------------------------------------------
09/25/2015 06:50:56 PM - Process(24626.24657) User(mqm) Program(amqrmppa)
Host(xxxxxxxxx) Installation(Installation1)
VRMF(8.0.0.3) QMgr(xxxxxxxxx)
AMQ9999: Channel 'CONNOO28' to host 'xxxxxxxxx (xx.xxx.xxx.xxx)' ended
abnormally.
EXPLANATION:
The channel program running under process ID 24626 for channel 'CONNOO28'
ended abnormally. The host name is 'xxxxxxxxx (xx.xxx.xxx.xxx)'; in some
cases the host name cannot be determined and so is shown as '????'.
ACTION:
Look at previous error messages for the channel program in the error logs to
determine the cause of the failure. Note that this message can be excluded
completely or suppressed by tuning the "ExcludeMessage" or "SuppressMessage"
attributes under the "QMErrorLog" stanza in qm.ini. Further information can be
found in the System Administration Guide.

So? What part of:

isn't completely clear?
Again, you post the most trivial of questions without any pretense of trying to investigate or even think for yourself.
Only this time you apparently can't even both to exert yourself enough to actually ask anything. You just post the error message and sit back.

When Application is trying to connect to Queue Manager.
Later i see below message, once the log started rolling.
MQQueueManager is not running on Property , Start MQQueueManager
12:06:24,849 ERROR [mailout] (Thread-96) JMS ExceptionMQJMS2005: failed to create MQQueueManager for 'servername:QM1'

I tried to investigate by closing the channel and killing the process id for that so that there will not be any instance of it running. Also, tried to recreate the channel. I changed the sharecnv value to 0, but still i am getting the same error again and again. However , I am able to connect to other queue manager, not sure what difference is there in other queue manager. |

So why didn't you mention any of this in the original post? Are we supposed to just know what you've done?
On the subject of things you've not told us, what environment is this JMS app running in? What is the JMS configuration?

Well if this works with another queue manager (another fact you neglected to mention) then the difference in configuration between the working and the non-working queue manager and/or the channel used by the application defined thereon would seem to be a key clue to your problem.
And something we can't possibly help with.
We've no way of determining the differences between 2 queue managers and their objects defined on your site.

Not to mention the Security settings

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

And what is this max channels being hit: 100; 1,000; 10,000; 50 lahks?
What is in the qmgr's ini file in regards to the channels section...

| Also, since you mentioned it is your application, one thing you should always do is to close the QMGR (QueueConnectionFactory) connection after you are done with making MQ calls |
