BPEL correlation


Correlation is a process that matches incoming messages to a particular BPEL process instance. Synchronous BPEL does not require correlation. Correlation is only required for asynchronous BPEL processes.

Oracle BPEL Process Manager automatically establishes correlation using WS-Addressing. However, manual content-based correlation is required if the asynchronous service doesn't support WS-Addressing or the BPEL message is coming from an external system.

Oracle BPEL Processor Manager has the following two methods for correlating asynchronous callback messages to the calling instance.

  • WS-Addressing

  • Correlation sets

One needs to write a manual correlation for the following scenarios:

  • Calling service does not support WS-Addressing.

  • When the asynchronous call has multiple layers. For example, Service A calls B, B calls C, and C Calls D. Response comes from D to A (instead of D to C to B to A). Another option in this scenario is to manipulate the replyTo header without implementing custom...
