On page 33 of the "Symantec Data Loss Prevention Oracle Installation and Upgrade Guide" (1-800-0900-2009-03-16), step 5, I did the following:
SQL> alter user mdsys account unlock;
alter user mdsys account unlock
ERROR at line 1:
ORA-01918: user 'MDSYS' does not exist
Is this a problem? What do I need to do?
