Oracle Study之--查看Oracle 版本运算字长(32/64位)方法
一、采用sqlplus查看
64位:
[oracle@rh7 ~]$ sqlplus '/as sysdba'

Oracle Database 11g
Enterprise Edition Release 11.2.0.3.0 - 64bit Production

SQL>
32位:
[oracle@rh65 ~]$ !sql
sqlplus '/as sysdba'

二、查看version
64位:
SQL> select * from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0
- 64bit Production
PL/SQL Release 11.2.0.3.0 -
Production
CORE 11.2.0.3.0 Production
TNS for Linux: Version
11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production
32位:
SQL> select * from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
- Production
PL/SQL Release 11.2.0.1.0 -
Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version
11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
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。
三、查看v$sql
64位:
SQL> select address from v$sql where rownum <2;
ADDRESS
----------------
00000000788E0A20
32位:
SQL> select address from v$sql where rownum
<2;
ADDRESS
--------
69A9E378
64位输出的是16位16进制,32位输出的是8位16进制数
