内存检查
检查内存空间
[root@localhost ~]# grep MemTotal /proc/meminfo
MemTotal: 8172940 kB
查看物理内存使用正常。
交换空间检查
[root@localhost ~]# grep SwapTotal /proc/meminfo
SwapTotal: 10485752 kB
查看交换分区满足要求。
磁盘空间需求
[root@localhost ~]# df

操作系统情况
检查操作系统版本
[root@localhost ~]# cat /etc/RedHat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 7)
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.9-78.ELlargesmp #1 SMP Wed Jul 9 16:03:59 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
系统软件补丁的查询
系统软件包无法安装,考虑用oracle10g
检查系统是否满足10的安装情况:
rpm -Uvh setarch-1.6-1.i386.rpm
rpm -Uvh compat-libstdc -33-3.2.3-47.3.i386.rpm
rpm -Uvh make-3.80-5.i386.rpm
