For security reasons, I wish to create a user whose sole
responsibility is to create, update, or delete users. I do not wish
this user to have any other power over the server's databases - hence
I am hesitant to allow this user to use the "SYSDBA" account.

However, in any documentation that I have read, I have not found that
SYSDBA could assign the rights to create/delete users to another user.

Is it possible? If so, how is it done?

Thanks for any help.
