A.1.3 Diagnosing AQ Issues

As previously noted, the Saga framework uses asynchronous messaging (AQ) as its event mesh. The Saga framework relies on AQ message propagation and message notification. To diagnose issues with propagation and notification, see Managing Queues in the Oracle Database Reference guide.

Key elements to monitor are:

• Queue Depth for Saga queues (messages pending consumption)

• Propagation latency in the topology

• Notification latency
