Oracle AQ

AQ is a unique database-integrated message queuing feature, built on the Oracle Streams information integration infrastructure. It allows diverse applications to communicate asynchronously through messages. Integration with the database provides unique message management functionality, such as auditing, tracking, and message persistence for security, scheduling, and message metadata analysis.

You can access AQ through PL/SQL, Java (using the oracle.AQ package), Java Message Service (JMS), or over the Internet using transport protocols such as HTTP, HTTPS, and SMTP. For Internet access, the client - a user or Internet application - and the Oracle server exchange structured XML messages.

AQ also provides transformations that are useful for enterprise application integration and a messaging gateway to automatically propagate messages to and from OracleAQ queues.
