Cannot find mandatory environment variable $DB
The Juke_Box custom server uses the DB environment variable. It must hold the fully-qualified path name of the directory which is used to access the configuration file, the music player program files, message files, and so on.
Check that the shell or program calling the Juke_Box custom server sets the DB environment variable, then restart the Juke_Box custom server.
