Symptoms

In our production environment many similar findOrder WS calls are sending to OSM Server all the time, for example

<FindOrder xmlns="http://xmlns.oracle.com/communications/ordermanagement">
    <SelectBy>
        <Field>
               <Path>/CustomerHeaders/OrderID</Path>
                   <EqualTo>ChangingOrderID</EqualTo>
        </Field>
   </SelectBy>
</FindOrder>

The "ChangingOrderID" values are different in each request.

The calls are taking longer time to return and in DB it can be seen that DB engine is spending most time in
