大家平时在维护oracle时，在各种操作系统下，都会用到一些unix操作系统命令来查看系统相关的信息，

详细的可以在附件中下载PDF格式

内 存:
——-
AIX: bootinfo -r
lsattr -E -lmem0
/usr/sbin/lsattr -E -l sys0 -a realmem
or use a tool as “topas” or “nmon” (these are utilities)

Linux: cat /proc/meminfo
/usr/sbin/dmesg | grep “Physical”
free (the free command)

HP: /usr/sam/lbin/getmem
grep MemTotal /proc/meminfo
/etc/dmesg | grep -i phys
wc -c /dev/mem
or us a tool as “glance”, like entering “glance -m” from prompt (is a utility)

Solaris: /usr/sbin/prtconf | grep “Memory size”

Tru64: /bin/vmstat -P | grep “Total Physical Memory”

交换页面:
———-
AIX: /usr/sbin/lsps -a

HP: /usr/sbin/swapinfo -a

Solaris: /usr/sbin/swap -l

Linux: /sbin/swapon -s
cat /proc/swaps
cat /proc/meminfo

操作系统版本:
————–
HP: uname -a

Linux: cat /proc/version

Solaris: uname -a
cat /etc/release (or other way to view that file, like “more /etc/release”)

Tru64: /usr/sbin/sizer -v

AIX: oslevel -r
lslpp -h bos.rte

AIX firmware:

lsmcode -c display the system firmware level and service processor
lsmcode -r -d scraid0 display the adapter microcode levels for a RAID adapter scraid0
lsmcode -A display the microcode level for all supported devices
prtconf shows many setting including memory, firmware, serial# etc..

CPU信息:
———
HP: ioscan -kfnC processor
getconf CPU_VERSION
getconf CPU_CHIP_TYPE
model

AIX: prtconf | grep proc
pmcycles -m
lsattr -El procx (x is 0,2, etc..)
lscfg | grep proc

Linux: cat /proc/cpuinfo

Solaris: psrinfo -v
prtconf

系统补丁:
———-
AIX: Is a certain fix (APAR) installed?
instfix -ik APAR_number
instfix -a -ivk APAR_number

To determine your platform. firmware level, at the command prompt, type:

lscfg -vp | grep -p Platform

The last six digits of the ROM level represent the platform. firmware date in the format, YYMMDD.

HP: /usr/sbin/swlist -l patch
swlist | grep patch

Linux: rpm -qa

Solaris: showrev -p
pkginfo -i package_name

Tru64: /usr/sbin/dupatch -track -type kit

网卡信息:
———
AIX: lsdev -Cc adapter
lsdev -Cc adapter | grep ent
lsdev -Cc if
lsattr -E -l ent1
ifconfig -a

Solaris: prtconf -D / prtconf -pv / prtconf | grep “card”
prtdiag | grep “card”
svcs -x
ifconfig -a (up plumb)

光驱挂载:
———-
AIX:
—-
# mount -r -v cdrfs /dev/cd0 /cdrom

SuSE Linux:
———–
# mount -t iso9660 /dev/cdrom /cdrom
# mount -t iso9660 /dev/cdrom /media/cdrom

Redhat Linux:
————-
# mount -t iso9660 /dev/cdrom /media/cdrom

Solaris:
——–
# mount -r -F hsfs /dev/dsk/c0t6d0s2 /cdrom

HPUX:
—–

mount -F cdfs -o rr /dev/dsk/c1t2d0 /cdrom

Other commands on Linux:
————————

Sometimes on some Linux, and some scsi CDROM devices, you might try

# mount /dev/sr0 /mount_point
# mount -t iso9660 /dev/sr0 /mount_point
