It is possible to connect to the database without specifying a password. Once you’ve done that you can then reset the passwords. I’m assuming that you’ve installed the database on your machine; if not you’ll first need to connect to the machine the database is running on.
Ensure your user account is a member of the
dbagroup. How you do this depends on what OS you are running.Enter
sqlplus / as sysdbain a Command Prompt/shell/Terminal window as appropriate. This should log you in to the database as SYS.Once you’re logged in, you can then enter
to reset the SYS password, and similarly for SYSTEM.
(Note: I haven’t tried any of this on Oracle 12c; I’m assuming they haven’t changed things since Oracle 11g.)
