方法:1、用“sqlplus /as sysdba”查询,64位会显示具体位数信息,32位不显示;2、用“v$version”视图查询会显示64位位数信息;3、用“v$sql”视图查询,32位输出为8位16进制数,64位是16位16进制数。
本教程操作环境:Windows10系统、Oracle 11g版、Dell G3电脑。
64位:
[oracle@qs-wg-db2 ~]$ sqlplus / as sysdba; SQL*Plus: Release 10.2.0.5.0 - Productionon Sun Sep 25 08:57:22 2011 Copyright (c) 1982, 2010, Oracle. All Rights Reserved. Connected to: Oracle Database 10g Enterprise EditionRelease 10.2.0.5.0 - 64bit Production With the Partitioning, OLAP, Data Miningand 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:

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。
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 whererownum<2; ADDRESS ---------------- 0000000196FDF7D8
