3、创建oinstall、dba用户组；

4、创建oracle用户及密码：

useradd -g oinstall -G dba oracle

5、修改系统参数：

将以下内容加入文件 /etc/sysctl.conf

# Added for oracle 11G, 20100814, by ljg
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.tcp_wmem = 262144 262144 262144
net.ipv4.tcp_rmem = 4194304 4194304 4194304
fs.aio-max-nr = 1048576
# /sbin/sysctl -p

# /sbin/sysctl -a

6、修改oracle用户设置：将以下内容加入到文件/etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

7、设置可插入认证模块 (PAM) 限制：将以下内容加入到文件/etc/pam.d/login

session required pam_limits.so

8、在全局 profile 文件中设置用户限制：将以下内容加入到文件/etc/profile

if [ $USER = "oracle" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384
