如何查看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
copyright (c) 1982, 2011, oracle. all rights reserved.
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 ~]$sqlplus/ as sysdba;
sql*plus: release 11.2.0.1.0 production onsun sep 25 08:55:48 2011
copyright (c) 1982, 2010, oracle. all rights reserved.
connected to:
oracle database 11g enterprise editionrelease 11.2.0.1.0 - production
with the partitioning, olap, data miningand real application testing options
方法二：查看v$version 视图
###32位：
sql> select * from v$version;
banner
--------------------------------------------------------------------------
oracle database 11g enterprise editionrelease 11.2.0.1.0 - production
pl/sql release 11.2.0.1.0 - production
core 11.2.0.1.0 production
tns for 32-bit windows: version 11.2.0.1.0- production
nlsrtl version 11.2.0.1.0 - production
###64位：
sql> select * from v$version;
banner
--------------------------------------------------------------------------------
oracle database 11g enterprise edition release 11.2.0.3.0 - 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 
address
--------
b50acdae
###64位：输出为16位16进制数
sql> select address from v$sql where rownum 
address
----------------
