2.停不必要的服务[RHEL5U1]
chkconfig acpid off
chkconfig anacron off
chkconfig apmd off
chkconfig auditd off
chkconfig autofs off
chkconfig avahi-daemon off
chkconfig bluetooth off
chkconfig cpuspeed off
chkconfig cups off
chkconfig firstboot off
chkconfig gpm off
chkconfig haldaemon off
chkconfig hidd off
chkconfig ip6tables off
chkconfig iptables off
chkconfig irqbalance off
chkconfig isdn off
chkconfig mcstrans off
chkconfig mdmonitor off
chkconfig microcode_ctl off
chkconfig netfs off
chkconfig pcscd off
chkconfig readahead_early off
chkconfig restorecond off
chkconfig rhnsd off
chkconfig rpcgssd off
chkconfig rpcidmapd off
chkconfig sendmail off
chkconfig setroubleshoot off
chkconfig smartd off
chkconfig xfs off
chkconfig yum-updatesd off
3.修改系统配置参数/etc/sysctl.conf
echo "kernel.shmall = 2097152">>/etc/sysctl.conf
echo "kernel.shmmax = 4294967295">>/etc/sysctl.conf
echo "kernel.shmmni = 4096">>/etc/sysctl.conf
echo "kernel.sem = 250 32000 100 128">>/etc/sysctl.conf
echo "net.ipv4.ip_local_port_range = 9000 65500">>/etc/sysctl.conf
echo "net.core.rmem_default = 262144">>/etc/sysctl.conf
echo "net.core.rmem_max = 2097152">>/etc/sysctl.conf
echo "net.core.wmem_default = 262144">>/etc/sysctl.conf
echo "net.core.wmem_max = 1048576">>/etc/sysctl.conf
echo "fs.file-max = 262144">>/etc/sysctl.conf
让参数生效
sysctl -p
注：
shmall 是全部允许使用的共享内存大小，shmmax 是单个段允许使用的大小。这两个可以设置为内存的 90%。
例如 16G 内存，16*1024*1024*1024*90% = 15461882265，shmall 的大小为 15461882265/4k(getconf PAGESIZE可得到) = 3774873。
6.创建ORACLE安装目录变更属主
mkdir -p /oracle/product/10.2.0/crs
mkdir -p /oracle/product/10.2.0/db
chown -R oracle:oinstall /oracle
7.修改ORACLE用户默认限制
echo "oracle soft nproc 2047">>/etc/security/limits.conf
echo "oracle hard nproc 16384">>/etc/security/limits.conf
echo "oracle soft nofile 4096">>/etc/security/limits.conf
echo "oracle hard nofile 65536">>/etc/security/limits.conf
echo "session required /lib/security/pam_limits.so">>/etc/pam.d/login
echo "session required pam_limits.so">>/etc/pam.d/login
echo "if [ $USER = "oracle" ]; then">>/etc/profile
echo " if [ $SHELL = "/bin/ksh" ]; then">>/etc/profile
echo " ulimit -p 16384">>/etc/profile
echo " ulimit -n 65536">>/etc/profile
echo "
