Oracle 基础知识:标准版的功能列表和 Incremental backup and recovery

由于Oracle数据库软件,可以自由的下载试用,所以很少有人会注意到企业版和标准版的不同。


在我的职业生涯中,曾经有限的次数,使用过专业版本的数据库。

有朋友问:

Oracle 的备份机制,增量备份需要额外购买什么组件包吗?

为什么我们要求公司管理员(并非专业DBA,兼职公司所有硬件维护授权的管理员)进行增量备份,对方说当前的oracle没有购买增量备份的服务,不能建立增量备份只能全库备份。


其实这的确是有限制的,以下输出来自 Oracle 标准版软件,通过 v$option 可以看到数据库中的选项列表,注意其中的: Incremental backup and recovery 选项,其值是 False。

如果使用标准版软件,的确是不能使用这个功能的。

这个记录来自 Oracle 9i版本,如果版本信息没有 Enterprise 字样,就说明是标准版:

[oracle@st ~]$ sqlplus "/ as sysdba"

SQL*Plus: Release 9.0.1.0.0 - Production on Mon Jul 24 10:40:25 2006

(c) Copyright 2001 Oracle Corporation.  All rights reserved.


Connected to:
Oracle9i Release 9.0.1.0.0 - Production
JServer Release 9.0.1.0.0 - Production

SQL> select * from v$version;

BANNER
----------------------------------------------------------------
Oracle9i Release 9.0.1.0.0 - Production
PL/SQL Release 9.0.1.0.0 - Production
CORE    9.0.1.0.0       Production
TNS for Linux: Version 9.0.1.0.0 - Production
NLSRTL Version 9.0.1.0.0 - Production

看一下Oracle的标准版支持的选件,为True的还真不多:

SQL> set linesize 120
SQL> col value for a5
SQL> select * from v$option where value='TRUE';
