is it say that all oracle server (10gR2, 11gR2) has a SYS account, this account existing as the oracle admin and it Is here when oracle just been installed?
so this can be the same type of account as the MS SQL sa account?
if so, changing the SYS account password alone should not impact the oracle installation and operation in anyway, right?
application connect to it should keep running well except the application also use this SYS account to connect to Oracle? which quit not possible.
