Displays the current database root file specification or the
    current recovery-unit journal (.ruj) file specification for a
    specific user of the database. You can use this statement to be
    sure you assigned the file specification you intended.

    The DISPLAY ROOT SPECIFICATION command is the default if no other
    keyword follows the DISPLAY ROOT command.

                                   NOTE

       Prior to Oracle Rdb Version 6.0, you could use the DISPLAY
       ROOT command to display an after-image journal (.aij) file
       specification. This is no longer an option; use the RMU Show
       After_Journal command instead.
