Engine-Managed Correlation

There are two ways that ActiveVOS can correlate messages that are received by a BPEL process: correlation sets and engine-managed correlation policy assertions. A correlation set uses message properties defined within a WSDL and BPEL process. Engine-managed correlation relies on WS-Addressing references in the SOAP header of a message to correlate a received message with the correct process instance.

If you use engine-manage correlation, you need only specify a policy assertion on a My Role partner link. Select a My Role partner link that is associated with a Partner Role in the same partner link. The engine-managed correlation policy assertion directs the ActiveVOS server to use WS-Addressing to transmit replyTo endpoint references during transmissions to the partner.

Example

<myRole allowedRoles="" binding="RPC"

   service="ManagedCorrelationServiceA">

  <wsa:Metadata>

   <wsp:Policy xmlns:abp="http://schemas.

    active-endpoints.com/ws/2005/12/policy"

     xmlns:wsp="http://schemas.xmlsoap.org

     /ws/2004/09/policy">

    <abp:engineManagedCorrelationPolicy/>

   </wsp:Policy>

  </wsa:Metadata>

</myRole>
