Signaling

 

Signaling is supported only on WebSphere MQ for z/OS.

Signaling is an option on the MQGET call to allow the operating system to notify (or signal) a program when an expected message arrives on a queue. This is similar to the get with wait function described in topic Waiting for messages because it allows your program to continue with other work while waiting for the signal. However, if you use signaling, we can free the application thread and rely on the operating system to notify the program when a message arrives.
