    有朋友在ITPUB上提问,如何查询Oracle各组件的版本信息。

其实这个问题,最好的方法是用opatch工具,可以查询得到详细的安装组件版本。
这个可以参考我的网站链接:

这里想说说其他的几个视图。有朋友提到了v$version 和 product_component_version 两个视图。
我们来看一下这两者有意思的关系.

首先看看两者的输出:

SQL> select * from PRODUCT_COMPONENT_VERSION;

PRODUCT VERSION STATUS
------------------------------ -------------------- ----------
NLSRTL 9.2.0.4.0 Production
Oracle9i Enterprise Edition 9.2.0.4.0 Production
PL/SQL 9.2.0.4.0 Production
TNS for Linux: 9.2.0.4.0 Production

SQL> select * from v$version;

BANNER
----------------------------------------------------------------
Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production
PL/SQL Release 9.2.0.4.0 - Production
CORE 9.2.0.3.0 Production
TNS for Linux: Version 9.2.0.4.0 - Production
NLSRTL Version 9.2.0.4.0 - Production

似乎不同,是么?
那我们再来看看这两者的来源,可以借用一下sqlplus的autotrace功能:

SQL> set autotrace trace explain
SQL> select * from v$version;

Execution Plan
----------------------------------------------------------
0 SELECT STATEMENT Optimizer=CHOOSE
1 0 FIXED TABLE (FULL) OF 'X$VERSION'

SQL> select * from PRODUCT_COMPONENT_VERSION;

Execution Plan
----------------------------------------------------------
0 SELECT STATEMENT Optimizer=CHOOSE
1 0 VIEW OF 'PRODUCT_COMPONENT_VERSION'
2 1 SORT (UNIQUE)
3 2 UNION-ALL
4 3 FIXED TABLE (FULL) OF 'X$VERSION'
5 3 FIXED TABLE (FULL) OF 'X$VERSION'

我们可以发现,这两者都来自底层表x$version,也就是说这两个视图同源,只不过展现有所不同而已。

查询一下x$version的基本信息:

SQL> col indx for 9999
SQL> col inst_id for 99
SQL> select * from x$version;

ADDR INDX INST_ID BANNER
-------- ----- ------- ----------------------------------------------------------------
B701CDCC 0 1 Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production
B701CDCC 1 1 PL/SQL Release 9.2.0.4.0 - Production
B701CDCC 2 1 CORE 9.2.0.3.0 Production
B701CDCC 3 1 TNS for Linux: Version 9.2.0.4.0 - Production
B701CDCC 4 1 NLSRTL Version 9.2.0.4.0 - Production

v$version显然是较为单纯的View,那么PRODUCT_COMPONENT_VERSION经过怎样的处理呢?
我们看一下这个视图的创建语句,学习一下Oracle的SQL技术:

CREATE OR REPLACE VIEW SYS.product_component_version (product, VERSION,
status)
AS
(SELECT SUBSTR (banner, 1, INSTR (banner, 'Version') - 1),
SUBSTR (banner,
INSTR (banner, 'Version') + 8,
INSTR (banner, ' - ') - (INSTR (banner, 'Version') + 8)
),
SUBSTR (banner, INSTR (banner, ' - ') + 3)
FROM v$version
WHERE INSTR (banner, 'Version') > 0
AND ( (INSTR (banner, 'Version') OR INSTR (banner, 'Release') = 0
))
UNION
(SELECT SUBSTR (banner, 1, INSTR (banner, 'Release') - 1),
SUBSTR (banner,
INSTR (banner, 'Release') + 8,
INSTR (banner, ' - ') - (INSTR (banner, 'Release') + 8)
),
SUBSTR (banner, INSTR (banner, ' - ') + 3)
FROM v$version
WHERE INSTR (banner, 'Release') > 0
AND INSTR (banner, 'Release')

很多东西只要深入一点点,就能发现问题的本质。
是不是很好玩呢?
