The Process Name attribute of a local or model queue gives the name of a process instance that identifies the application started by the queue manager when a trigger event occurs.
The process does not have to be defined when the local queue is defined, but it must be available for a trigger event to occur.
If the Process Name attribute was intended to give the name of a channel to be started, the queue definition must have its Usage attribute set to Transmission, and have triggering enabled.
The Process Name attribute of a triggered transmission queue gives the name of a channel to be started by the queue manager when a trigger event occurs.
The Process Name attribute for the specified queue identifies a channel that does not exist.
If you have not deliberately set this attribute to the name of a non-existent channel, check that the value of the Process Name attribute is spelt correctly.
