Oracle Database - SYSOPER privilege
About
A user can connect with different levels of privileges, namely:
SYSDBA (the root of administrator of the database)
and SYSOPER.
SYSOPER allows a user to perform basic operational tasks, but without the ability to look at user data.
By default, all members with the SYSDBA privilege have all privileges granted by the SYSOPER privilege.
