Parameters

 

Parameter	Description
msgProducer	Set the property of this producer.
timeToLive	Set the property to this value.

Remarks

Time-to-live (in milliseconds) determines the expiration time of a message.

•	If the time-to-live is non-zero, the expiration is the sum of that time-to-live and the sending client’s current time (GMT). This rule applies even within sessions with transaction semantics—the timer begins with the send call, not the commit call.

•	If the time-to-live is zero, then expiration is also zero—indicating that the message never expires.

 

Programs can use this property to define a default time-to-live for messages that this producer sends. Individual sending calls can override this default value.

Whenever your application uses non-zero values for message expiration or time-to-live, you must ensure that clocks are synchronized among all the host computers that send and receive messages. Synchronize clocks to a tolerance that is a very small fraction of the smallest or time-to-live.
