 void receive_request_service_contexts(org.omg.PortableInterceptor.ServerRequestInfo ri)
          Method called from a specific interception point, when the active replica group member receives a request from the client (via the gateway) Operations are performed if the called method is get_state, wait_set_state, activate/deactivate_object,etc. (mainly operations that are not allowed to reach the application object, because it does not implement those methods
 void receive_request(org.omg.PortableInterceptor.ServerRequestInfo ri)
          Method called from a specific interception point, when the active replica group member receives a request from the client (via the gateway) Operations are performed mainly on incoming requests that have to be called on the application object as methods; for active replication these are dispatched in a total order

          Method called from a specific interception point when the replica sends an exception to the client
