This is a text description of Figure 14-2, "Running DRDA server Stored Procedures".
The functions illustrated in the figure are described in the surrounding text.
This is a simplified view of running a DB2 stored procedure on an Oracle application by calling the stored procedure from the DRDA server through the gateway.
The application calls the "emproc" stored procedure from an Oracle instance, which uses the gateway (DG4DRDA) to call the stored procedure from the DRDA server.
In this example, "emproc" is a DB2/MVS stored procedure.
