Thank you !! Appreciate all of your kind advices!
Now the fact is based on the audit data, me issued the command from standby server which I am assuming it is standby database, make the production database shutdown..
My supervisor told me that he only wants me to be comfortable about the fact I did something wrong... I feel very depressed, hi brothers and sisters, do you think I should look for another job....?
Thank you...
Really appreciate Meiguolaotu providing some suggestions...
