You must run a separate CREATE SERVER statement for each remote database you intend to access.
For example, if a remote server named TestAA is running on the computer banana and owns three databases (db1, db2, db3), you would configure the local database server similar to this:
CREATE SERVER TestAAdb1 CLASS 'saodbc' USING 'banana:2638/db1' CREATE SERVER TestAAdb2 CLASS 'saodbc' USING 'banana:2638/db2' CREATE SERVER TestAAdb3 CLASS 'saodbc' USING 'banana:2638/db3';
If you do not specify a /database-name value, the remote connection uses the remote database server's default database.
