Creating a New Administration Account

The installation process creates an account named SYSTEM. This account is considered an administrator account because it has DBA access.

Using an Oracle best practice, we can create our own administrator account and password so that we can create database user accounts when needed.
Steps to do:
1.Go to your Database home page

Login as your default adminstrator user
Username=system
Password=Jude
(Note:password will the one which u have given at the time of oracle configuration)
