问题
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.
回答1:
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
回答2:
If SQLPLUS is not available, you can also reset an expired password from within SQL Developer:
- Save your connection information (if not done already)
- Right click on your connection
- Click on the “Reset Password” option in the menu, enter old/new password blah blah blah
