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，
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
