Symptoms

E-Business Suite R12 Integrated SOA Gateway, Service Invocation Framework Installation issues

The business implementation requires the use of the business events system with WebServiceInvokerSubscription for outbound integration (configured through Workflow Administrator).

However when enabling multi-threading with the above configuration, duplicate outbound messages are frequently sent when the system is under load.

The duplicate messages then cause errors in the applications integration layer.

For example if the system raises 100 events, 100 calls get made to the target server regardless of how many threads are configured.

When the configuration is changed back to a single thread, the duplicate messages stop.

But with multiple threads, the NONCE value added to the SOAP Header by the WebserviceInvokerSubscription gets duplicated.

For example, when 100 messages are sent with 10 threads, 12 errors are generated from our target server saying that the same NONCE value had been reused.

This is preventing customer from increasing the capacity to send messages.

The complete error is included below for reference:
