dba_registry 和 v$option 与 Oracle 特新及组件

一. 先看官网对这2个视图的说明

1.1 V$OPTION

This view lists database options and features. Typically, although not always, options must be separately purchased and installed, whereas features come with the product and are enabled based on the product that is running (Standard Edition, Enterprise Edition, or Personal Oracle). If you want to see a list of all installed options for the database, use the DBA_REGISTRY view. See "DBA_REGISTRY".

Column	Datatype	Description
PARAMETER	VARCHAR2(64)	Name of the option (or feature)
VALUE	VARCHAR2(64)	TRUE if the option (or feature) is installed

1.2 DBA_REGISTRY

DBA_REGISTRY displays information about the components loaded into the database.

Related View

USER_REGISTRY displays information about the components loaded into the database that are owned by the current user.

Column	Datatype	NULL	Description
COMP_ID	VARCHAR2(30)	NOT NULL	Component identifier
COMP_NAME	VARCHAR2(255)		Component name
VERSION	VARCHAR2(30)		Component version loaded
STATUS	VARCHAR2(11)		Component status: · INVALID · VALID · LOADING · LOADED · UPGRADING · UPGRADED · DOWNGRADING · DOWNGRADED · REMOVING · REMOVED
MODIFIED	VARCHAR2(20)		Time when the component was last modified
NAMESPACE	VARCHAR2(30)	NOT NULL	Component namespace
CONTROL	VARCHAR2(30)	NOT NULL	User that created the component entry
SCHEMA	VARCHAR2(30)	NOT NULL	User that contains the objects for the component
PROCEDURE	VARCHAR2(61)		Validation procedure
STARTUP	VARCHAR2(8)		Indicates whether the component requires a startup after the upgrade (REQUIRED) or not
PARENT_ID	VARCHAR2(30)		Parent component identifier

二. 说明

通过上面的2个说明，可以看出：

（1）v$option 视图显示的DB 所有的选项或者特性。 这些特性需要单独的购买和安装。

（2）dba_registry 视图显示的是已经安装的组件。并且该视图的信息也比v$option 详细。
