Table 12-34 OracleAQNavigationMode Members

Member Name Description

FirstMessage

Retrieves the first message that is available and matches the search criteria. This resets the position to the beginning of the queue.

FirstMessageMultiGroup

Indicates that a call to DequeueArray resets the position to the beginning of the queue, and dequeues messages that are available and match the search criteria. Messages are dequeued till the dequeueCount limit is reached. The dequeued messages can belong to different transaction groups.

You can use the OracleAQMessage.TransactionGroup property to distinguish between messages from different transaction groups. All messages from the same transaction group have the same value for the OracleAQMessage.TransactionGroup property.
