Only available on Oracle 8i and above.
Access to some V$ tables are required to use this option. A list of these permissions is available in the Help. Press F1 from the Logminer window and follow the appropriate link.
If you cannot access V$PARAMETER, V$LOGFILE, V$SESSION, V$VERSION, the screen will still work, but the screen will not do some things automatically for you (such as tell you if utl_file is not setup, or automatically determine where your log files are stored, and so on).
If you cannot access things that are actually required (like execute privs on dbms_logmnr) the screen will tell you what is required, and the permissions you are missing will be highlighted.
