Data Dictionary and Dynamic Performance Views

Overview of the Data Dictionary
An important part of an Oracle database is its data dictionary, which is a read-only set of tables that provides administrative metadata about the database. A data dictionary contains information such as the following:
· The definitions of every schema object in the database, including default values for columns and integrity constraint information
· The amount of space allocated for and currently used by the schema objects
· The names of Oracle Database users, privileges and roles granted to users, and auditing information related to users (see "User Accounts")
The data dictionary is a central part of data management for every Oracle database. For example, the database performs the following actions:
· Accesses the data dictionary to find information about users, schema objects, and storage structures
· Modifies the data dictionary every time that a DDL statement is issued (see "Data Definition Language (DDL) Statements")
Because Oracle Database stores data dictionary data in tables, just like other data, users can
query the data with SQL. For example, users
can run SELECT
statements to determine their
privileges, which tables exist in their schema, which columns are in these tables, whether indexes
are built on these columns, and so on.
Contents of the Data Dictionary
The data dictionary consists of the following types of objects:
· Base tables
These underlying tables store information about the database. Only Oracle Database should write to and read these tables. Users rarely access the base tables directly because they are normalized and most data is stored in a cryptic format.
· Views
These views decode the base table data into useful information, such as user or table names, using
joins and
WHERE
clauses to simplify the information. These views contain the names and description of all objects in the data dictionary. Some views are accessible
to all database users, whereas others are intended for administrators only.
Typically, data dictionary views are grouped in sets. In many cases, a set consists of three views containing similar information and distinguished from each other by their prefixes, as shown in Table 6-1. By querying the appropriate views, you can access only the information relevant for you.
Prefix |
User Access |
Contents |
Notes |
|
Database administrators |
All objects |
Some |
|
All users |
Objects to which user has privileges |
Includes objects owned by user. These views obey the current set of enabled roles. |
|
All users |
Objects owned by user |
Views with the prefix
|
Not all views sets have three members. For example, the data dictionary contains a
DBA_LOCK
view but no
ALL_LOCK
view.
The system-supplied
DICTIONARY
view contains the names and abbreviated descriptions of all data dictionary views. The following query of this view includes partial sample output:
SQL> SELECT * FROM DICTIONARY ORDER BY TABLE_NAME;
TABLE_NAME COMMENTS
------------------------------ ----------------------------------------
ALL_ALL_TABLES Description of all object and relational
tables accessible to the user
ALL_APPLY Details about each apply process that
dequeues from the queue visible to the
current user
Views with the Prefix DBA_
Views with the prefix
DBA_
show all relevant information in the entire database.
DBA_
views are intended only for administrators.
For example, the following query shows information about all objects in the database:
SELECT OWNER, OBJECT_NAME, OBJECT_TYPE FROM DBA_OBJECTS ORDER BY OWNER, OBJECT_NAME;
Views with the Prefix ALL_
Views with the prefix
ALL_
refer to the user's overall perspective of the database. These views return information about schema objects to which the user has access through public or explicit grants of
privileges and roles, in addition to schema objects that the user owns.
For example, the following query returns information about all the objects to which you have access:
SELECT OWNER, OBJECT_NAME, OBJECT_TYPE FROM ALL_OBJECTS ORDER BY OWNER, OBJECT_NAME;
Because the ALL_
views obey the current set of enabled roles, query results depend on which roles are enabled, as shown
in the following example:
SQL> SET ROLE ALL;
Role set.
SQL> SELECT COUNT(*) FROM ALL_OBJECTS;
COUNT(*)
----------
68295
SQL> SET ROLE NONE;
Role set.
SQL> SELECT COUNT(*) FROM ALL_OBJECTS;
COUNT(*)
----------
53771
Application developers should be cognizant of the effect of roles when using
ALL_
views in a
stored procedure, where
roles are not enabled by default.
Views with the Prefix USER_
The views most likely to be of interest to typical database users are those with the prefix
USER_
. These views:
· Refer to the user's private environment in the database, including metadata about schema objects created by the user, grants made by the user, and so on
· Display only rows pertinent to the user, returning a subset of the information in the
ALL_
views
· Has columns identical to the other views, except that the column
OWNER
is implied
· Can have abbreviated
PUBLIC
synonyms for convenience
For example, the following query returns all the objects contained in your schema:
SELECT OBJECT_NAME, OBJECT_TYPE FROM USER_OBJECTS ORDER BY OBJECT_NAME;
The DUAL Table
DUAL
is a small table in the data dictionary that Oracle
Database and user-written programs can reference to guarantee a known result. The dual table is useful when a value must be returned only once, for example, the current date and time. All database users have access to
DUAL
.
The DUAL
table has one column called
DUMMY
and one row containing the value
X
. The following example queries
DUAL
to perform an arithmetical operation:
SQL> SELECT ((3*4)+5)/3 FROM DUAL;
((3*4)+5)/3

二.數據字典
Oracle數據字典是有表和視圖組成,存儲有關數據庫結構信息的一些數據庫對象。數據庫字典描述了實際數據是如何組織的。比如一個表的創建者信息,創建時間信息,所屬表空間信息,用戶訪問權限信息等。對它們可以象處理其他數據庫表或視圖一樣進行查詢,但不能進行任何修改。它們存放在SYSTEM表空間中,當用戶在對數據庫中的數據進行操作時遇到困難就可以訪問數據字典來查看詳細的信息。用戶可以用SQL語句訪問數據庫數據字典。
Oracle數據庫字典通常是在創建和安裝數據庫時被創建的,Oracle數據字典是Oracle數據庫系統工作的基礎,沒有數據字典的支持,Oracle數據庫系統就不能進行任何工作。數據字典中的表是不能直接被訪問的,但是可以訪問數據字典中的視圖。
2.1 數據字典內容包括:
1,數據庫中所有模式對象的信息,如表、視圖、簇、及索引等。
2,分配多少空間,當前使用了多少空間等。
3,列的缺省值。
4,約束信息的完整性。
5,Oracle用戶的名字。
6,用戶及角色被授予的權限。
7,用戶訪問或使用的審計信息。
8,其它產生的數據庫信息。
2.2 數據字典分爲數據字典表和數據字典視圖
2.2. 1 數據字典表
數據字典表裏的數據是Oracle系統存放的系統數據,而普通表存放的是用戶的數據。爲了方便的區別這些表,這些表的名字都是用"$"結尾,這些表屬於SYS用戶。
數據字典表由$ORACLE_HOME/rdbms/admin/sql.bsq 腳本創建, 這個腳本里又調用了其他的腳本來創建這些數據字典表。 在那些創建腳本里有基表的創建SQL。 感興趣的自己打開看看。
Oracle 對數據字典表的說明:
These underlying tables store information about the database. Only Oracle Database should write to and read these tables. Users rarely access the base tables directly because they are normalized and most data is stored in a cryptic format.
這些數據字典表,只有Oracle 能夠進行讀寫。
SYS用戶下的這些數據字典表,存放在system 表空間下面,表名都用"$"結尾,爲了便於用戶對數據字典表的查詢, Oracle對這些數據字典都分別建立了用戶視圖,這樣即容易記住,還隱藏了數據字典表表之間的關係,Oracle針對這些對象的範圍,分別把視圖命名爲DBA_XXXX, ALL_XXXX和USER_XXXX。
關於這3類視圖,下面有介紹。
Oracle爲了便於彙總數據字典表的信息,把所有的數據字典都彙集到dictionary表裏了,通過對這個表的查詢,我們可以很方便的找到數據庫提供的數據字典。
2.2.2 數據字典視圖
動態性能視圖由腳本:$ORACLE_HOME/rdbms/admin/catalog.sql 創建, 該腳本也只是一個總的調用,在該腳本里由調用了其他的腳本。 感興趣的可以自己打開看一下,在那些腳本里,可以看到視圖的創建SQL.
這是因爲這個腳本會創建動態視圖,所以在做DB 升級的時候,也需要執行這個腳本,重新創建視圖。
數據字典視圖分2類:靜態數據字典(靜態性能視圖) 和 動態數據字典(動態性能視圖)
2.2.2.1 靜態數據字典(靜態性能視圖)
靜態數據字典中的視圖分爲三類,它們分別由三個前綴夠成:user_*、 all_*、 dba_*。
user_*:該視圖存儲了關於當前用戶所擁有的對象的信息。(即所有在該用戶模式下的對象)
all_*:該試圖存儲了當前用戶能夠訪問的對象的信息, 而不是當前用戶擁有的對象。(與user_*相比,all_* 並不需要擁有該對象,只需要具有訪問該對象的權限即可)
dba_*:該視圖存儲了數據庫中所有對象的信息。(前提是當前用戶具有訪問這些數據庫的權限,一般來說必須具有管理員權限)
這些視圖由SYS用戶創建的,所以使用需要加上SYS,爲了方便, Oracle爲每個數據字典表的視圖頭建立了同名字的公共同義詞(public synonyms). 這樣簡單的處理就省去了寫sys.的麻煩。
示例:
(1)user_tables:主要描述當前用戶擁有的所有表的信息,主要包括表名、表空間名、簇名等。通過此視圖可以清楚瞭解當前用戶可以操作的表有哪些。
SQL>select * from user_tables;
(2)user_indexes: 查詢該用戶擁有哪些索引。
SQL>select index_name from user_indexes;
(3)user_views: 查詢該用戶擁有哪些視圖
SQL>select view_name from user_views;
(4)user_objects:查詢該用戶擁有哪些數據庫對象,對象包括表、視圖、存儲過程、觸發器、包、索引、序列、JAVA文件等。
SQL>select object_name from user_objects;
(5)user_users:主要描述當前用戶的信息,主要包括當前用戶名、帳戶id、帳戶狀態、表空間名、創建時間等。
SQL>select * from user_users;
(6)all_objects:查詢某一用戶下的所有表、過程、函數等信息。
SQL>select owner , object_name ,object_type from all_objects
2.2.2.2 動態數據字典(動態性能視圖)
除了靜態數據字典中三類視圖,其他的字典視圖中主要的是V$視圖,之所以這樣叫是因爲他們都是以V$或GV$開頭的。這些視圖會不斷的進行更新,從而提供了關於內存和磁盤的運行情況,所以我們只能對其進行只讀訪問而不能修改它們。
Throughout its operation, Oracle Database maintains a set of virtual tables that record current database activity. These views are calleddynamic performance views because they are continuously updated while a database is open and in use. The views, also sometimes called V$ views。
V$視圖是基於X$虛擬視圖的。V$視圖是SYS用戶所擁有的,在缺省狀況下,只有SYS用戶和擁有DBA系統權限的用戶可以看到所有的視圖,沒有DBA權限的用戶可以看到USER_和ALL_視圖,但不能看到DBA_視圖。與DBA_,ALL,和USER_視圖中面向數據庫信息相反,這些視圖可視的給出了面向實例的信息。
動態性能表用於記錄當前數據庫的活動,只存於數據庫運行期間,實際的信息都取自內存和控制文件。 DBA可以使用動態視圖來監視和調節數據。

2.3 視圖家族
在Oracle的絕大多數數據字典視圖中都有象DBA_TABLES,ALL_TABLES和USER_TABLES這樣的視圖家族。Oracle中有超過100個視圖家族,下表列出了最重要和最常用的視圖家族,需要注意的是每個視圖家族都有一個DBA_,一個ALL_ 和一個USER_視圖。
