1 Oracle 11g 的內核要求：
fs.file-max = 512 * PROCESSES
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.HTTP://www.aliyun.com/zixun/aggregation/6133.html">ipv4.ip_local_port_range = 560.html">1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
2 檢查內核參數是否滿足要求：
其值大於要求的值可以不做修改。
3 修改需要修改的參數。
在/etc/sysctl.conf 開機檔案中，輸入以下內容：
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
4 使修改的內核參數立即生效：
linuxsuse:/proc/sys/net/ipv4 # sysctl –p
