COBOL Call

Parameters

Parameter Description
message Set the expiration of this message.
value Set the expiration to this value.

Remarks

Sending calls set the expiration header automatically. The JMS specification defines this call for symmetry.

Sending calls record the expiration time (in milliseconds) of the message in this field:

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

The server discards a message when its expiration time has passed. However, the JMS specification does not guarantee that clients do not receive expired messages.
