This graphic depicts optimizing data transfers and shows the following:
1. A client does an array fetch by means of OCI/Pro* or some other tool to an Oracle server. The Oracle server resides on one machine by itself.
2. The Oracle server connects by means of HS_RPC_FETCH_SIZE to a second machine with an agent and the non-Oracle system on it.
3. Each system has a respective data store so that there is a data store for the Oracle server and another for the non-Oracle system.
