来源:互联网 发布:ppt简约排版 知乎 编辑:程序博客网 时间:2024/04/29 01:47
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

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

Description
COMP_ID
VARCHAR2(30)
NOT NULL

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。
