Migrating From AQ

Oracle Database 23ai includes a migration path from Advanced Queuing (AQ) to Transactional Event Queues (TxEventQ), to take advantage of enhanced performance and scalability for event-driven architectures.

Advanced Queuing (AQ) has been Oracle’s database messaging system for managing asynchronous communication in enterprise applications, allowing reliable queuing and message delivery. TxEventQ leverages Kafka-based event queuing, offering improved throughput, lower latency, and greater scalability, making it ideal for modern event-driven architectures and high-volume event processing.

The DBMS_AQMIGTOOL package facilitates a smooth migration process, designed to be non-disruptive and allowing the parallel operation of AQ and TxEventQ during the transition, enabling a smooth cut-over with minimal downtime for your applications.

The migration from AQ to TxEventQ is suitable for various scenarios:

• Scaling up existing AQ-based applications
• Modernizing legacy messaging systems
• Improving performance for high-volume event processing
