Globalization Problem

Question

Hi,All.
I am chinese,and recently I have joined a project using occi.In our project,there are three major tires:database,server program,and client program.Our Oracle Databe 10.1.0.2 will run on Red Hat Linux Advanced Server 3,server c++ program ,which is occi based ,will run on Red Hat Linux 9,and our client program is Microsoft MFC programs.As you know ,the client will pass chinese characters to the server program,then the server program will do :store the data to the database,update some record based on the character recieved ,fetch some data from database ocorrding the characters recieved from the client,or something else like that. The next post I will show you our test code.
