本文提供了针对不同服务器规格（64位64GB内存、64位16GB内存及32位2~4GB内存）的Oracle 10g RAC集群参数配置示例。详细介绍了包括shmall、shmmax在内的关键内核参数设置。

# Added for Oracle 10g RAC                  -- 64bit, 64G内存的server
kernel.shmall = 16777216
kernel.shmmax = 68719476736
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
