#一般情况下使用root或者oracle用户查都可以。

# 总核数 = 物理CPU个数 X 每颗物理CPU的核数

# 总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 超线程数

--查看物理CPU个数

[oracle@enmo ~]$ cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l

--查看每个物理CPU中core的个数(即核数)

cat /proc/cpuinfo| grep "cpu cores"| uniq

--查看逻辑CPU的个数

[oracle@enmo ~]$ cat /proc/cpuinfo| grep "processor"| wc -l

[oracle@enmo ~]$ 

--查看CPU信息（型号）

[oracle@enmo ~]$ cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
