linux下oracle11g安装

一.创建用户和组

#groupadd oinstall

#groupadd dba

#useradd -g oinstall -G dba oracle

#passwd oracle

二.配置内核

编辑/etc/sysctl.conf

fs.file-max = 512 * PROCESSES

kernel.shmall = 2097152

kernel.shmmax = 2147483648

kernel.shmmni = 4096

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

/etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

/etc/pam.d/login

session required /lib/security/pam_limits.so

session required pam_limits.so

三.创建目录

#mkdir -p /u01/app

#chown -R oracle:oinstall /u01/app

#chmod -R 775 /u01/app

#mkdir -p /u02/oradata

#chown oracle:oinstall /u02/oradata

#chmod 775 /u02/oradata

四.设置环境变量

用oracle用户进入编辑.bash_profile

DISPLAY=local_host=0.0;

export DISPLAY
