RabbitMQ is a message broker which is executed in low-level AMQP protocol and acts as an intermediator between two application in the communication process.
Why is Max channels set to 300 in qm.ini?
Example of MaxChannels set to 300 in the Channels stanza inside the qm.ini file: 2. Client applications are holding the channels longer than needed, thereby not freeing up the channels for other application to use. 3. Client applications are not freeing the channels via MQDISC before terminating.
Why are there Max channels in MQ 6.0?
Client applications are not freeing the channels via MQDISC before terminating. This can occur if the application, or client system, is killed or if there are network glitches. In MQ 6.0, this item was a leading cause for reaching the max channels condition.
Where is the qm.ini file for MQ 7.1?
– For MQ 7.1 and later, the location of the qm.ini file is given by the WorkPath specified in the HKLM\\SOFTWARE\\IBM\\WebSphere MQ key. For example, the path and the name for a configuration file for a queue manager called QMNAME is: Example of MaxChannels set to 300 in the Channels stanza inside the qm.ini file: 2.
How does the queue manager work in MQ 7.x?
In MQ 7.x and later, with the introduction of full-duplex channels, the queue manager can now ask periodically via a heartbeat if the client at the other end of the channel is still alive. If not alive anymore, then the connection is terminated, eliminating “orphan” channels.
