查看Oracle32位还是64位(x86orx64)
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 318:44:05 2014 Copyright (c) 1982, 2011, Oracle. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release11.2.0.3.0 - 64bit Production With the Partitioning, OLAP, Data Mining and RealApplication 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 ~]$sqlplus/ as sysdba; SQL*Plus: Release 11.2.0.1.0 Production onSun Sep 2508:55:48 2011 Copyright (c) 1982, 2010, Oracle. All rightsreserved. Connected to: Oracle Database 11g Enterprise EditionRelease11.2.0.1.0 - Production With the Partitioning, OLAP, Data Miningand RealApplication Testing options
方法二:查看v$version 视图
###32位: SQL> select * from v$version; BANNER -------------------------------------------------------------------------- Oracle Database 11g Enterprise EditionRelease11.2.0.1.0 - Production PL/SQL Release 11.2.0.1.0 - Production CORE 11.2.0.1.0 Production TNS for 32-bit Windows: Version 11.2.0.1.0- Production NLSRTL Version 11.2.0.1.0 - Production ###64位: SQL> select * from v$version; BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release11.2.0.3.0 - 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<2; ADDRESS -------- B50ACDAE ###64位:输出为16位16进制数 SQL> select address from v$sql whererownum<2; ADDRESS ---------------- 00000000C18D79C8
