Write in brief about all oracle object privileges
In : MCA Subject : Advanced Database AdministrationWhen many users have access to database items, privileges can be used to regulate authorization. Every object has a person who owns it. Privileges determine whether a user can edit an object that belongs to another user. The instance administrator, a user with the ADMIN privilege, or, in the case of privileges to a specific object, the owner of the object, can grant or withdraw privileges.
The "Providing authorization to objects through privileges" section in the Oracle TimesTen In-Memory Database Operations Guide provides a detailed description of how to grant and revoke privileges for the different objects. In addition, the following sections provide a quick reference on all privileges that are required to perform TimesTen operations:
- System privileges
- Object privileges
- Privilege hierarchy
- The PUBLIC role
System privileges
A system privilege is the right to perform a particular action or to perform an action on any object of a particular type. Objects include tables, views, materialized views, synonyms, indexes, sequences, cache groups, replication schemes and PL/SQL functions, procedures and packages. Only the instance administrator or a user with ADMIN privilege can grant or revoke system privileges.

|
Privilege |
Object type |
Description |
|
DELETE |
Table |
Enables a user to delete from a table. |
|

Privilege hierarchy
Some privileges confer other privileges. For example, ADMIN privilege confers all other privileges. The CREATE ANY TABLE system privilege confers the CREATE TABLE object privilege.
The CACHE_MANAGER privilege also includes the ability to start and stop the cache agent and the replication agent and to perform cache grid operations.
CREATE ANY CACHE GROUP confers the CREATE CACHE GROUP privilege for any cache group.
