Hi All,
I am trying to open as many channel connection to send messages to MQ for load testing. I am using JMS client , which uses transport type to for connecting to MQ Server. I am able to open connection till 300 , but when i am trying to open 400 connection at once , I am getting below exception.
com.ibm.msg.client.jms.DetailedIllegalStateException: JMSWMQ0018: Failed to connect to queue manager 'QM1' with connection mode 'Client' and host name '11.57.83.20(1425)'. Check the queue manager is started and if running in client mode, check there is a listener running. Please see the linked exception for more information.

What is the maximum number of simultanious connections the queue manager is configured to accept? Is there any chance it's only configured to accept 300? Or at least less than 400?

Then you need to expand your search to the queue manager's listener and the network hardware. Something's blocking you, possibly because it thinks you're a DDoS.

| Thanks for your quick response. Will verify the hardware limitation if it is preventing me to extend the connections. |

Also check the channel's attributes like MAXINST and MAXINSTC.
Could any one of those be set at 300 ?

Seriously? Are you aware how long that's been out of support?
Why are you load testing a version of MQ that's been dead years, and may not perform that well under load anyway, and may now be conflicting with more modern OS & network components?

| Sorry, It was my fault to use older version. I checked these values on later version of MQ (version 7.0.1.9) as well. It shows the value 999999999 as a default. Please suggest If I need to change these values or any other attribute. |

Did you just check the settings, or did you try the failing code on the newer version?
There's no guarantee that the software interprets any value or works the same way between versions, especially when the gap is as large as the one you're indicating.

| I created another queue manager on linux server with 400 server connection channel and 400 remote queues. After that I tried to open these many channels for sending 100 messages of 4 kb to each of these queues simultaneously. |
