Sun Java System Messaging Server 6.3 Administration Guide

1.10 Performance and Tuning

This section provides some post-installed performance and tuning information. For more complete information on this topic, refer to Performance Considerations for a Messaging Server Architecture in Sun Java Communications Suite 5 Deployment Planning Guide.

1.10.1 Java Message Queue (JMQ) Tuning

A configuration parameter in JMQ that may need tweaking in a typical JMQ deployment. Change the following line in the file /usr/share/lib/imq/props/broker/ from:

#  imq.autocreate.destination.maxNumProducers=100

to imq.autocreate.destination.maxNumProducers=-1.

If you don't do this, you may see a message in the JMQ log that mentions Destination Conflicts, and you may lose notifications on large system deployments.
