Managing a Group of Activities with a Scope Activity

A scope activity provides a container and a context for other activities. A scope provides handlers for faults, events, compensation, data variables, and correlation sets. Using a scope activity simplifies a BPEL flow by grouping functional structures. This grouping enables you to collapse them into what appears to be a single element in Oracle BPEL Designer.

The following example shows a scope named Scope_FulfillOrder. This scope invokes the FulfillOrder Oracle Mediator component, which determines the shipping method for the order.

<scope name="Scope_FulfillOrder">
    <variables>
        <variable name="lFulfillOrder_InputVariable"
        messageType="ns17:requestMessage"/>
    </variables>
    <sequence>
        <assign name="Assign_OrderData">
            <copy>
                <from variable="gOrderInfoVariable"
                    query="/ns4:orderInfoVOSDO"/>
                <to variable="lFulfillOrder_InputVariable"
                    part="request" query="/ns4:orderInfoVOSDO"/>
            </copy>
        </assign>
        <invoke name="Invoke_FulfillOrder"
            inputVariable="lFulfillOrder_InputVariable"
            partnerLink="FulfillOrder.FulfillOrder"
            portType="ns17:execute_ptt" operation="execute"/>
    </sequence>
</scope>
