查看Oracle 32位還是64位(x86 or x64)

如何查看Oracle 32位還是64位(x86 or x64)。

方法一：使用sqlplus

###64位：
[oracle@db01 ~]$ sqlplus / as sysdba
 
SQL*Plus: Release 11.2.0.3.0 Production on Fri Oct 3 18:44:05 2014

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
 
SQL>
如果是64位，用sqlplus 連上之後會顯示具體的位元資訊，32位則不會顯示。
 
 
###32位：
[oracle@db01 ~]$sqlplus/ 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 - Production
With the Partitioning, OLAP, Data Miningand Real Application Testing options
 

方法二：查看v$version 視圖

###32位：
SQL> select * from v$version;
 
BANNER
--------------------------------------------------------------------------
Oracle Database 11g Enterprise EditionRelease 11.2.0.1.0 - Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for 32-bit Windows: Version 11.2.0.1.0- Production
NLSRTL Version 11.2.0.1.0 - Production
 
###64位：
SQL> select * from v$version;
 
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE 11.2.0.3.0 Production
TNS for Linux: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 – Production
和第一種方法一樣，64位會顯示具體的位元資訊，32位不會顯示。

方法三：查看v$sql 視圖

###32位：輸出為8位16進位數
SQL> select address from v$sql whererownum<2;
 
ADDRESS

B50ACDAE
 
###64位：輸出為16位16進位數
SQL> select address from v$sql where rownum<2;
 
ADDRESS
