Message Delivery Mode
Each Broker message has a storage type of either volatile or guaranteed. The document storage type supports the JMS message delivery mode.
A JMS message delivered with
persistent delivery mode is represented by a
Broker message with
guaranteed storage type.
A JMS message delivered with
non-persistent delivery mode is represented by a
Broker message with
volatile storage type.
Whether a Broker message is written to durable storage depends on the combination of its storage type and the receiving Broker client's storage type. A Broker message is written to durable storage only when its storage type and the receiving Broker client's storage type are both guaranteed.
