linux 下安装Oracle 自动设置sysctl.conf 相关内核参数的脚本

sysctl  -w kernel.shmmax=`free  |  awk '/Mem/ {print $2  -1024}' ` 
sysctl  -w kernel.shmmni=5120
sysctl  -w kernel.shmall=2097152
sysctl  -w "kernel.sem=250 32000 100 128"
sysctl  -w fs.aio-max-nr=1048576
sysctl  -w fs.file-max=6815744
sysctl  -w "net.ipv4.ip_local_port_range=9000 65500"
sysctl  -w net.core.rmem_default=262144
sysctl  -w net.core.rmem_max=4194304
sysctl  -w net.core.wmem_default=262144
sysctl  -w net.core.wmem_max=1048576

以上数值参考自oracle 官方安装文档
