I have just tried to login to my db via sql developer as system so i can create a new user. It has come with an error that the password has expired.
I have googled a bit but cannot see how to reset the system user password. I guess this is a security issue.
My problem is how can I log in as system if the password has expired? How can I unexpire the password without logging in as System users. I seem to be stuck here in a loop where I cannot reset the password expiration.
Open up cmd.exe
and type in SQLPLUS
Enter user-name: SYSTEM
Enter password: the expired password
It will now let you type in a new password for the SYSTEM user
