In Oracle, you can manage user permissions and roles by following these steps:

  1. Create a user: Use the CREATE USER statement to create a user. For example, CREATE USER username IDENTIFIED BY password;
  2. Grant permissions: Use the GRANT statement to grant users the necessary permissions. For example, “GRANT SELECT, INSERT, UPDATE ON table_name TO username;”
  3. Create role: Use the CREATE ROLE statement to create a role. For example, CREATE ROLE role_name;
  4. Grant roles: Use the GRANT statement to assign permissions to a role. For example, GRANT SELECT, INSERT, UPDATE ON table_name TO role_name;
  5. Assigning roles: Assigning roles to users using the GRANT statement. For example, GRANT role_name TO username;
  6. Revoke permissions and roles: Use the REVOKE statement to remove a user’s permissions or roles. For example, REVOKE SELECT ON table_name FROM username;
  7. Viewing user permissions and roles: You can check a user’s permissions and roles by querying system views. For example, use the SQL statement SELECT * FROM USER_ROLE_PRIVS WHERE USERNAME = ‘username’;
  8. Change user password by using the ALTER USER statement. For example, ALTER USER username IDENTIFIED BY new_password;

By following the steps above, it is possible to effectively manage user privileges and roles in an Oracle database.
