1.安装必须的系统包
[root@secDB Server]# cd /media/RHEL_5.3\ x86_64\ DVD/Server/
rpm -ivh setarch-2*
rpm -ivh make-3*
rpm -ivh glibc-2*
rpm -ivh libaio-0*
rpm -ivh compat-libstdc++-33-3*
rpm -ivh compat-gcc-34-3*
rpm -ivh compat-gcc-34-c++-3*
rpm -ivh libXp-1*
rpm -ivh openmotif-2*
rpm -ivh compat-db-4*
----------------------------------------------------------
2.修改sysctl.conf文件并使用“sysctl -p”命令使之生效
# vi /etc/sysctl.conf
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
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
# /sbin/sysctl -p
