6 Privileges

The following sections describe privileges that are required to perform TimesTen operations:

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, 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.

Object privileges

An object privilege is the right to perform a particular action on an object or to access another user's object. Objects include tables, views, materialized views, indexes, sequences, cache groups, replication schemes and PL/SQL functions, procedures and packages.

An object's owner has all object privileges for that object, and those privileges cannot be revoked. The object's owner can grant object privileges for that object to other database users. A user with ADMIN privilege can grant and revoke object privileges from users who do not own the objects on which the privileges are granted.

Table 6-2 Object privileges

Privilege Object type Description

DELETE

Table

Allows a user to delete from a table.

EXECUTE

PL/SQL package, procedure or function

Allows a user to execute a PL/SQL package, procedure or function directly.

FLUSH

Cache group

Allows a user to flush a cache group.

INDEX

Table or materialized view

Allows a user to create an index on a table or materialized view.

INSERT

Table

Allows a user to insert into a table.

LOAD

Cache group

Allows a user to load a cache group

REFERENCES

Table or materialized view

Allows a user to create a foreign key dependency on a table or materialized view.

The REFERENCES privilege on a parent table implicitly grants SELECT privilege on the parent table.

REFRESH

Cache group

Allows a user to refresh a cache group

SELECT

Table, sequence, view or materialized view

Allows a user to select from a table, sequence, view or materialized view.

The SELECT privilege allows a user to perform all operations on a sequence.

A user can be granted the SELECT privilege on a view without having the SELECT privilege on its detail table.

UNLOAD

Cache group

Allows a user to unload a cache group

UPDATE

Table

Allows a user to update 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. Table 6-3 shows the privilege hierarchy.

Table 6-3 Privilege hierarchy

Privilege Confers these privileges

ADMIN

All other privileges including CACHE_MANAGER

CREATE ANY INDEX

INDEX ON (any table or materialized view)

CREATE ANY MATERIALIZED VIEW

CREATE MATERIALIZED VIEW

CREATE ANY PROCEDURE

CREATE PROCEDURE

CREATE ANY SEQUENCE

CREATE SEQUENCE

CREATE ANY SYNONYM

CREATE SYNONYM

CREATE ANY TABLE

CREATE TABLE

CREATE ANY VIEW

CREATE VIEW

DELETE ANY TABLE

DELETE (any table)

EXECUTE ANY PROCEDURE

EXECUTE (any procedure)

INSERT ANY TABLE

INSERT (any table)

SELECT ANY SEQUENCE

SELECT (any sequence)

SELECT ANY TABLE

SELECT (any table, view or materialized view)

UPDATE ANY TABLE

UPDATE (any table)


Cache group privileges have a separate hierarchy except that ADMIN confers the CACHE_MANAGER privilege.

The CACHE_MANAGER privilege confers these privileges:

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. The built-in procedures and utilities for these operations are documented in Oracle TimesTen In-Memory Database Reference.

CREATE ANY CACHE GROUP confers the CREATE CACHE GROUP privilege for any cache group.

The PUBLIC role

All users of the database have the PUBLIC role. In a newly created TimesTen database, by default PUBLIC has SELECT and EXECUTE privileges on various system tables and views and PL/SQL functions, procedures and packages. You can see the list of objects by using this query:

SELECT table_name, privilege FROM sys.dba_tab_privs WHERE grantee='PUBLIC';

Privileges that are granted to PUBLIC as part of database creation cannot be revoked. To see a list of these privileges, use this query:

SELECT table_name, privilege FROM sys.dba_tab_privs WHERE grantor='SYS';
