If the system is performing very slowly and system events are not working,
there may be a problem with the WebSphere MQ publish/subscribe broker.
- Open the file /var/mqm/qmgrs/<queue manager
name>/qm.ini and look for the following:
MaxActiveChannels=1000Broker:
If you see this entry, replace the Channels and Broker parameters with the
following:
Channels:
MaxChannels=1000
MaxActiveChannels=1000
SyncPointIfPersistent=yes
- Save your changes
- Shut down Business Integration Connect (see Shutting down below).
- Stop WebSphere MQ by:
- Stopping the publish/subscribe broker:
endmqbrk -m <hostname>.queue.manager
- Stopping the listener:
endmqlsr -m <hostname>.queue.manager
- Stopping the queue manager:
endmqm <hostname>.queue.manager
- Create and start WebSphere MQ, using the instructions in the WebSphere
Business Integration Connect Installation Guide. However, do not
perform steps 2 through 4 in the procedure.
- Restart Business Integration Connect, using the instructions in the
WebSphere Business Integration Connect Installation Guide.
