I am writing a C++ program to connect to the db2 remotely. I want to get all the database name under an instant(node) in the server, what can I do? I have try the db2api function sqledosd() and sqledgne(), but I can only get the database name that I've cataloged. What should I do? Isn't it available for db2api/ cli / SQL Statement? And how can I know whether the database was created by user or system? Thanks very much~!

SQL statement to get the database name : LIST DATABASE DIRECTORY or LIST NODE DIRECTORY

To know whether the database was created by user or system : LIST TABLES
