2.2.2.10 MQMSGDELIVERY

The MQMSGDELIVERY enumeration defines values for the Message.DeliveryGuarantee property. The values of the enumeration indicate whether the Message is recoverable if a service interruption occurs in the message queuing system.

 typedef enum 
 {
   MQMSGDELIVERY_EXPRESS = 0,
   MQMSG_DELIVERY_RECOVERABLE = 1
 } MQMSGDELIVERY;

MQMSGDELIVERY_EXPRESS:  The Message is not recovered when a service interruption occurs in the message queuing system. A client of this protocol selects this option if message throughput is preferred over the risk of message loss.

MQMSG_DELIVERY_RECOVERABLE:  The Message SHOULD be recoverable for most service interruptions in the message queuing system. A client of this protocol selects this option to minimize the risk of message loss, even if the computer on which the Message resides crashes.

Used by:

• get IMSMQMessage::Delivery

• put IMSMQMessage::Delivery

The MQMSGDELIVERY enumeration values correspond to the enumeration values for Message.DeliveryGuarantee, as shown in the following table:

MQMSGDELIVERY	Message.DeliveryGuarantee
MQMSGDELIVERY_EXPRESS	Express
