I have an Oracle Database system that I have been given which I need to change the initorcl.ora file. I have tried to connect internal without a password and the system denies me with an invalid username/password error. I have also tryed connecting as as sysdba but that didn't work either. I was not here when this system was configured and none of the people who did the configuration work here any longer. Any ideas as to how I can get into the system so to shutdown the database make the changes and restart?
