Enhanced Performance You can reduce the load on your source DB instance by routing read queries from your applications to the read replica.
This privilege is useful for system administrators who need to export data but who should not be allowed to change data. It is also useful for people who must run reports and compile information but not change data.
A user with the FULL privilege can also write to all the data. Note that Oracle system and object authorizations are still enforced. The FULL authorization turns off the access mediation check at the individual row level.
If a row label has no compartments, then access is determined by the group authorizations. However, when compartments do exist and access to them is authorized, then the group authorization is bypassed. This allows a privileged user whose label matches all the compartments of the data to access any data in any particular compartment, independent of what groups may own or otherwise be allowed access to the data.
Note that if the data label is null or invalid, then the user is denied access. This is a very powerful privilege, because the user can potentially become a user with FULL privileges. This privilege cannot be granted to a trusted stored program unit.
When a user updates a row label, the new label and old label are compared, and the required privileges are determined. The user can raise the level up to his or her maximum authorized level. For example, an authorized user can raise the level of a data row that has a level lower than his own minimum level.
It can be raised above the current session level, but it cannot change the compartments. The user can lower the level to any level equal to or greater than his or her minimum authorized level.
It lets the user change compartments and groups to anything that is currently defined as a valid compartment or group within the policy, while maintaining the level.
