如何查看Oracle 32位还是64位(x86 or x64)。
如何查看oracle 32位还是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 连上之后会显示具体的位数信息，32位则不会显示。
###32位：
[oracle@db01 ~]$sqlplus/ as sysdba;
SQL*Plus: Release 11.2.0.1.0 Production onSun Sep 25 08:55:48 2011

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$version 视图
###32位：
SQL> select * from v$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$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE 11.2.0.3.0 Production
TNS for Linux: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 – Production
和第一种方法一样，64位会显示具体的位数信息，，32位不会显示。
方法三：查看v$sql 视图
###32位：输出为8位16进制数
SQL> select address from v$sql whererownum
ADDRESS
--------
B50ACDAE
###64位：输出为16位16进制数
SQL> select address from v$sql where rownum
ADDRESS
----------------
