Remarks

An OracleAQMessage object consists of control information (metadata) and Payload (data). The control information is exposed by various properties on the OracleAQMessage object and is used by Oracle Database Advanced Queuing to manage messages. The payload is the information stored in the queue.

Note:

An instance of OracleAQMessage cannot be re-used across multiple operations of OracleAQQueue public method Enqueue() or EnqueueArray(), if the payload is an XmlReader. This is a direct consequence of the forward-only semantics of the XmlReader, as an Enqueue() or EnqueueArray() operation internally invokes a read operation on the XmlReader to extract the data to be enqueued.
