1.查看操作系统内存信息
AIX $ /usr/sbin/lsattr -E -l sys0 -a realmem
Linux $ /usr/sbin/dmesg | grep "Physical:"
HP $ grep MemTotal /proc/meminfo
dmesg | grep "physical"
swapinfo -t
Solaris $ /usr/sbin/prtconf | grep "Memory size"
Tru64 $ /bin/vmstat -P | grep "Total Physical Memory"
2.查看SWAP信息
AIX $ /usr/sbin/lsps -a
HP $ /usr/sbin/swapinfo -a
Linux and Tru64 $ /sbin/swapon -s
Solaris $ /usr/sbin/swap -1
3.查看CPU数量
root 用户下
/usr/platform/sun4u/sbin/prtdiag
4.查看系统日志：
hp_ux $ /var/adm/syslog/
5.查看文件系统
hp_ux:

6.查看操作系统补丁信息
AIX $ instfix -a -ivk APAR_number
HP $ /usr/sbin/swlist -l patch
Linux $ rpm -qa
Solaris 32-bit $ pkginfo -i package name
Solaris 64-bit $ showrev -p
Tru64 $ /usr/sbin/dupatch -track -type kit
7.查看进程信息
ps aux|sort +5
ipcs -pmb 查看端口
netstat -an | grep '1521'
8.查看操作系统版本
