To access the Oracle database, you can use either the SQL*Plus tool or the Oracle SQL Developer tool.

The steps to log in to an Oracle database using the SQL*Plus tool are as follows:

  1. Open the command line window (On Windows system, you can use the cmd command to open it, on Linux/Unix system, you can use the terminal window).
  2. Type in the following command to connect to the Oracle database:
sqlplus username/password@database

In this case, the username is the username of the database user, the password is the corresponding password, and the database is the address or service name of the database. For example:

sqlplus scott/tiger@localhost:1521/orcl
  1. Pressing the Enter key will prompt for the input of the database user’s password.
  2. After entering the password, press the Enter key to successfully log in to the Oracle database.

The steps to login to an Oracle database using the Oracle SQL Developer tool are as follows:

  1. Open the Oracle SQL Developer tool.
  2. Click on the plus icon in the top left corner, or select the “New Connection” option in the menu.
  3. Connection name: Customize the name of the connection.
  4. Username: the username of the database user.
  5. Password: The corresponding password.
  6. Hostname: The address or name of the database’s host.
  7. Port: The port number of the database.
  8. SID: The service name or SID of the database.
  9. Click on the “Test” button to verify if the connection information is correct.
  10. Click the ‘connect’ button to successfully log in to the Oracle database.

Please note that before using the above methods to log in to the Oracle database, it is necessary to correctly install and configure the Oracle database, as well as have the appropriate permissions and the correct username and password.
