• Open cmd, input: Sqlplus/nolog

• INPUT: Conn username/[email protected] Database name

• And of course there are other ways:

1. Sql>conn/as syddba; You can log in to the Oracle Super Admin user (no user and password required).

2. Sql>conn Username/password; You can log in to a normal user by entering a user name and password.

3. Sql>conn Username/[email protected] Address: port/ORCL; This command provides access to the Oracle user installed on top of the IP address. Note The SYS user is ORCL

Why do you use Sqlplus to lose password when you are prompted

ORA-12560:TNS: Protocol Adapter error
