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

方法二：查看v$version 视图###32位：
SQL> select * from v$version;

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<2;

ADDRESS

###64位：输出为16位16进制数
SQL> select address from v$sql where rownum<2;
