Hi Guys,

I have an application that uses MQ Java API to connect to MQ and perform operations like get/put/access.

MQ server/client jars: 8

In my testing to simulate slow network, I've added a network simulator between my application and MQ server to add a network delay of 5 seconds.
Command:
sudo -S /sbin/tc qdisc add dev eth0 root netem delay 5000ms

This command will delay every request to MQ server by 5 seconds.

Now in my testing, I am getting 2537, channle not available.

com.ibm.mq.MQException: MQJE001: Completion Code '2', Reason '2537'.

I've gone through the docs, it means firewall is blocking or max connection limit.

Please let me know how to handle this with a network delay of 5 seconds.
How can we handle this situation in slow network.


Many Thanks!
