Path Environment Variables

The server environment variables isolate the file system from the actual computer names. Wherever a server name is expected, the Env. button enables you to select, create, or delete server variables.

For example, in the dialog box below, Archive is a variable name that represents the server d:\archive\2010. Creating a database using this variable name enables you to move the database by simply changing the value of the variable.

See Server Environment Variables for information on setting up Server Environment Variables.

MD is a predefined variable that cannot be changed and refers to the database root directory. This value is often the default and normally does not need to be selected.
ROOT is a predefined variable that cannot be changed and refers to the D3 File System root directory. At run time, it is replaced by the root directory specified at install time on the specified server.
