use full commitment control and journalling for everything
It would really surprise me if SAP's benchmarks included journaling.
But my order entry applications follow a traditional header-line model, where the order is entered, then a series of line items are entered. ÂEach entry adds or changes a record on the server, immediately.
Under my header-line model, there's no need for commitment control. ÂBut RPG-based commitment control doesn't add much overhead, if or when needed.
