The requirements for configuration files containing data type definitions are:
The files must use the naming convention name.dt
The files must be located on the database search path. The default search path is:
Personal data types--HomeDirectory/.dt/types
System-wide data types--/etc/dt/appconfig/types/language
Built-in data types--/usr/dt/appconfig/types/language. You should not use this directory.
For information on modifying the database search path, see "Setting the Value of a Search Path".
