linux怎么查看oracle版本

要得到具体的行数据，一般并不是执行两个左右的i/o 就可以得到行数据。单独来看，这不是大问题，甚至根本注意不到。

不过，如果这种行所占的比例相当大，而且有大量用户在访问这些行，你就会注意到这种副作用了。

[oracle@db-server-01 ~]$ which sqlplus

/u01/app/oracle/product/10.2.0/db_1/bin/sqlplus

[oracle@db-server-01 ~]$ file /u01/app/oracle/product/10.2.0/db_1/bin/sqlplus

/u01/app/oracle/product/10.2.0/db_1/bin/sqlplus: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), not stripped

找到了oracle官网网站的Operating System Requirements，内容如下：

Operating System Requirements

The following or later versions of the operating system are required for Oracle Database 11g Release 2 (11.2):

Asianux Server 3 SP2

Oracle Linux 4 Update 7

Oracle Linux 5 Update 2 (with Red Hat Compatible Kernel)

Oracle Linux 5 Update 5

Oracle Linux 6

Oracle Linux 6 (with Red Hat Compatible Kernel)

Red Hat Enterprise Linux 4 Update 7

Red Hat Enterprise Linux 5 Update 2

Red Hat Enterprise Linux 5 Update 5 (with the Oracle Unbreakable Enterprise Kernel for Linux)

Red Hat Enterprise Linux 6

Red Hat Enterprise Linux 6 (with the Oracle Unbreakable Enterprise Kernel for Linux)

SUSE Linux Enterprise Server 10 SP2

SUSE Linux Enterprise Server 11

Starting with Oracle Database 11g Release 2 (11.2), the Security Enhanced Linux (SE Linux) feature is supported for Oracle Linux 4, Oracle Linux 5, Oracle Linux 6, Red Hat Enterprise Linux 4, Red Hat Enterprise Linux 5, and Red Hat Enterprise Linux 6.

从oracle官方网站上罗列的linux系统来看，根本就没有ubuntu *** 作系统。我们再来看一下Linux发行版列表，发现oracle就不支持基于Debian的linux系统。所以我就抛弃了想在ubuntu安装oracle的想法，想在centos上安装了。至少centos还是redhad的分支。
