CentOS 系統調校：

關閉 SELinux
#> setenforce 0
#> sed -i 's/SELINUX=.*$/SELINUX=disabled/' /etc/selinux/config  

停用 NetworkManager
#> service NetworkManager stop
#> chkconfig NetworkManager off

調整系統核心參數

#> ipcs -l

編輯 /etc/sysctl.conf
從最下方加上這幾行

# for DB2
# shmmax: 4GB
# shmall: 3.5GB
fs.file-max = 8192

kernel.sem = 250 64000 32 2048

套用後再確認一次

#> sysctl -p
#> ipcs -l
