Routing Messages to the Same Instance

Oracle BPEL Process Manager supports a message aggregation feature. When multiple messages are routed to the same process/partner link/operation name, the first message is routed to create a new instance and subsequent messages can be routed to continue the created instance using a midprocess receive activity.

Message aggregation enables you to use the same operation (or event name) in an entry receive activity and a midprocess receive activity.

Note:

  • This feature only performs aggregation, and not resequencing. This feature does not resequence messages arriving out of order into an ordered format. Therefore, the first message only means the first message processed. This may be different from the first message in a time sequence order.

  • You must use correlation sets to take advantage of the message aggregation feature.

  • Synchronous operations as ambiguous calls (at both beginning and midprocess receive activities) are supported. However, this is not a recommended use of this feature and should be avoided.
