There are three default accounts and passwords after Oracle installation:
1. Username: sys Password: change_on_install
2. Username: system Password: manager
3. Username: scott Password: tiger
If the account is forgotten, you can use one of the default account users and passwords (such as: system/manager), then log in in the PL/SQL management tool, and run the query statement "select username from dba_users" to query all oracle account.
If the password is forgotten, use one of the default accounts, then log in in the PL/SQL management tool, and run "alter user username identified password (new password);" This statement to modify the password will forget the username of the password Replace it and set a password
