Follow the steps to get guidance on the entire process:
1. Procedure to log in and establish connection with the Database:
SYSDBA helps us to login and generate secure connections with the database using the SQL Command Line. The SYS username & password or operating system (OS) authentication can also be used for this purpose.
1. Log in to the Oracle Database using any valid user account.
2. On Windows: Choose Oracle Database in the All Programs section and Run SQL Command-Line.
3. The SQL Command Line Window appears.
4. In the SQL Command Line prompt, enter the following command:
CONNECT SYS/password AS SYSDBA
Use the password for the SYS user. It is set upon installation of Windows or Linux configuration. The slash (/) indicates that the database should enable the user with operating system (OS) authentication. When the user connects with OS, he is effectively logging in to the database as user SYS.
2. Create User:
The method of creating a user on the Oracle Database involves the following syntax:
create user<username> identified by “<password>”;
The system account is a predefined administrative account generated automatically when Oracle is installed. It performs administrative tasks and account management. It is employed to create a user (schema).
The database is the default authentication for a new user. The user is assigned an encrypted password. Authentication can be done via external authentication using the operating system level. Once the user is connected as SYSTEM, the CREATE USER command is used to generate a new account.
3. Grant Access:
The next step directs us to add privileges to the account using the GRANT statement. GRANT is an important responsibility-driven statement with many possibilities. Still, the prime functionality of the command is to manage the privileges and permission rights of both users and roles throughout the database. Adding the RESOURCE role allows the user to create named types. The RESOURCE role enables a user to have the privileges to create procedures, generate triggers, and type within the user's schema.
4. Assign DBA Role:
The DBA role allows the user to not only create custom-named types but also modify and destroy them.
5. Grant Create Session:
If we wish to ensure the user has privileges to connect to the database, we must use the GRANT CREATE SESSION statement. All privileges can be granted by using GRANT ANY PRIVILEGE. By default, a database user has no privileges to connect.
