檢視 Oracle 是32位還是64位的方法

方法一：使用sqlplus

64位：

[oracle@qs-wg-db2 ~]$ sqlplus / as sysdba;

SQL>

如果是64位，用sqlplus 連上之後會顯示具體的位數資訊，32位則不會顯示。

32位：

C:\Users\Administrator.DavidDai>sqlplus/ as sysdba;

方法二： 檢視v$version 檢視

32位：

SQL> select * from v$version;

和第一種方法一樣，64位會顯示具體的位數資訊，32位不會顯示。

方法三：檢視v$sql 檢視

32位：輸出為8位16進位制數

SQL> select address from v$sql whererownum<2;
