Oracle 12c 企业版的需要6.4G大小的磁盘空间，标准版需要6.1G大小的磁盘空间。/tmp 需要至少1G的大小。从上面结果得知，磁盘空间完全满足。
3）检查软件要求(Checking the Software Requirements)
3.1 操作系统版本检测
Oracle 12 c 只支持64位的Linux系统。不支持32Linux平台，这也许是以后的趋势了。Operating System Requirements for x86-64 Linux Platforms。 Oracle 的官方文档明确列出了支持下面三个Linux版本
[root@getoraclelnx01 /]# uname -m
x86_64
[root@getoraclelnx01 /]# uname -r
2.6.32-200.13.1.el5uek
[root@getoraclelnx01 /]# more /etc/RedHat-release
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
[root@getoraclelnx01 ~]# uname -a
Linux getoraclelnx01.gfg1.esquel.com 2.6.32-200.13.1.el5uek #1 SMP Wed Jul 27 21:02:33 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
[root@getoraclelnx01 Server]# lsb_release -id
Distributor ID: EnterpriseEnterpriseServer
Description: Enterprise Linux Enterprise Linux Server release 5.7 (Carthage)
[root@getoraclelnx01 Server]#
3.2 检查oracle 12c所需包
关于Oracle 12c所需包，从官方文档看，不同版本的操作系统似乎有所不同，Oracle Linux 5 and Red Hat Enterprise Linux 5需要安装下面一些包
