或者使用sqlplus命令登陆数据库，如果是64位的，显示如下：
如何判断oracle的版本和位数
一、
打开orcale安装目录，如：D:\app\SSG\product\11.2.0\dbhome_1
11.2.0这个目录名就是版本
二、
主要有以下几种方法可以用来确定Oracle的位数:
1.通过SQLPLUS登录即可看出
a.64位登录时就有显示
$ sqlplus "/ as sysdba"
SQL*Plus: Release 9.2.0.4.0 - Production on Wed Nov 16 15:27:28 2005
Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production
With the Partitioning option
JServer Release 9.2.0.4.0 - Production
b.32位的无显示
[oracle@jumper oracle]$ sqlplus "/ as sysdba"
SQL*Plus: Release 9.2.0.4.0 - Production on Wed Nov 16 15:19:03 2005
Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production
With the Partitioning option
JServer Release 9.2.0.4.0 - Production
c.从v$version获取
SQL select * from v$version;
BANNER
------------------------------------------------------------
Oracle9i Enterprise Edition Release 9.2.0.6.0 - Production
PL/SQL Release 9.2.0.6.0 - Production
CORE 9.2.0.6.0 Production
TNS for 32-bit Windows: Version 9.2.0.6.0 - Production
NLSRTL Version 9.2.0.6.0 - Production
2.从v$sql视图获取
a.如果输出为8位16进制数，则为32位Oracle
SQL select address from v$sql where rownum2;
ADDRESS
--------
578428D8
b.如果输出为16位16进制数，则为64位Oracle
SQL select address from v$sql where rownum2;
ADDRESS
----------------
000000040DFA01E0
3.使用系统命令file
a.如果输出带有32-bit字样为32位Oracle
[oracle@jumper oracle]$ file $ORACLE_HOME/bin/oracle
/opt/oracle/product/9.2.0/bin/oracle: setuid setgid ELF 32-bit LSB executable, Intel 80386..
b.如果输出带有64-bit字样为64位Oracle
$ file $ORACLE_HOME/bin/oracle
/opt/oracle/product/9.2.0/bin/oracle: ELF 64-bit MSB executable SPARCV9 Version 1..
查看Oracle 是32位还是64位的方法
方法一：使用sqlplus64位：[Oracle@qs-wg-db2 ~]$ sqlplus / as sysdba; SQL*Plus: Release 10.2.0.5.0 - Productionon Sun Sep 25 08:57:22 2011 Copyright (c) 1982, 2010, Oracle. All Rights Reserved. Connected to:Oracle Database 10g Enterprise EditionRelease 10.2.0.5.0 - 64bit ProductionWith the Partitioning, OLAP, Data Miningand Real Application Testing options SQL 如果是64位，用sqlplus 连上之后会显示具体的位数信息，32位则不会显示。 32位：C:\Users\Administrator.DavidDaisqlplus/ as sysdba; SQL*Plus: Release 11.2.0.1.0 Production onSun Sep 25 08:55:48 2011 Copyright (c) 1982, 2010, Oracle. All rights reserved. Connected to:Oracle Database 11g Enterprise EditionRelease 11.2.0.1.0 - ProductionWith the Partitioning, OLAP, Data Miningand Real Application Testing options 方法二： 查看v$version 视图32位：SQL select * from v$version; BANNER--------------------------------------------------------------------------Oracle Database 11g Enterprise EditionRelease 11.2.0.1.0 - ProductionPL/SQL Release 11.2.0.1.0 - ProductionCORE 11.2.0.1.0 ProductionTNS for 32-bit Windows: Version 11.2.0.1.0- ProductionNLSRTL Version 11.2.0.1.0 - Production 64位：SQL select * from v$version; BANNER----------------------------------------------------------------Oracle Database 10g Enterprise EditionRelease 10.2.0.5.0 - 64biPL/SQL Release 10.2.0.5.0 - ProductionCORE 10.2.0.5.0 ProductionTNS for Linux: Version 10.2.0.5.0 -ProductionNLSRTL Version 10.2.0.5.0 – Production 和第一种方法一样，64位会显示具体的位数信息，32位不会显示。
