How to copy or clone one user to other in oracle?

To copy or clone a user in Oracle, you can use the following steps:

1. Connect to the Oracle database as a user with administrative privileges (e.g. SYSDBA).
2. Create a new user by cloning the existing user using the following SQL command: CREATE USER new_user IDENTIFIED BY password;
3. Grant all the necessary privileges to the new user by copying them from the existing user using the following SQL command: GRANT CONNECT, RESOURCE TO new_user;
4. If the existing user has specific privileges or roles assigned, you can copy them to the new user using the following SQL command: GRANT role_name TO new_user;
5. To copy all objects from the existing user to the new user, you can use the Oracle Data Pump utility or export/import tools.
6. Finally, make sure to test the new user's access and privileges by connecting to the database using the new user's credentials.

Remember to replace "new_user" with the desired username, "password" with the password for the new user, and "role_name" with any specific roles that need to be copied from the existing user.
