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 rownum<2;

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 rownum<2;
　　
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 ..
