Does the problem affect only remote queues?

If the problem affects only remote queues, check the following:

1. Check that the programs that should be putting messages to the remote queues have run successfully.

2. If you use triggering to start the distributed queuing process, check that the transmission queue has triggering set on. Also, check that the trigger monitor is running.

3. If necessary, start the channel manually. See WebSphere MQ Intercommunication for information about how to do this.

4. Check the channel with a PING command.

See WebSphere MQ Intercommunication for information about how to define channels.
