查看 Oracle 是32位还是64位的方法

monkeybird

方法一：使用sqlplus

64位：

[oracle@dbserver~]$ sqlplus / as sysdba;

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\monkeybird>sqlplus/ as sysdba;

 

SQL*Plus: Release 11.2.0.1.0 Production onSun Sep 25 08:55:48 2011

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;
