Dennis: Thanks for your message. Now I have changed sys password by the following command: alter user sys identified by xxxxxxx But when I try to login from sql plus window by using sys, I cannot successfully login. Also I get an error message. The message is something like "connection to sys should be as sysdba or sysoper". So my question is what sys for? Thank you very much!
