1.操作系统相关信息

Oracle 12cR1 支持Linux 5，Linux 6

[root@DB12c ~]# lsb_release -id

Distributor ID: RedHatEnterpriseServer

Description: Red Hat Enterprise Linux Server release 6.2 (Santiago)

[root@DB12c ~]# uname -an

Linux DB12c 2.6.32-220.el6.x86_64 #1 SMP Wed Nov 9 08:03:13 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

2.内存大小

Oracle 要求1GB，建议2GB或者更多

[root@DB12c ~]# grep MemTotal /proc/meminfo

MemTotal: 2570976 kB

3.Swap空间大小

内存为2GB--16GB的时候，Swap等于内存大小

[root@DB12c ~]# grep SwapTotal /proc/meminfo

SwapTotal: 3145720 kB

4.Temp空间大小

Oracle要求至少1GB的temp空间

[root@DB12c ~]# df -h /tmp

Filesystem Size Used Avail Use% Mounted on

/dev/sda3 3.0G 69M 2.8G 3% /tmp

5.磁盘空间

安装企业版的Oracle软件至少需要6.4GB的磁盘空间

这里将会选择/u01作为ORACLE_HOME

[root@DB12c ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda1 13G 3.5G 8.7G 29% /

tmpfs 1.3G 264K 1.3G 1% /dev/shm

/dev/sda6 1006M 18M 938M 2% /home

/dev/sda3 3.0G 69M 2.8G 3% /tmp

/dev/sda2 9.9G 151M 9.2G 2% /u01

6.安装所需要的RPM包

这里我们选择使用光盘yum源来安装rmp包

yum -y install unixODBC-devel-2.2.14-11.el6.i686

[root@DB12c ~]# chmod +x pach.sh

[root@DB12c ~]# sh pach.sh

7.创建用户和组

[root@DB12c ~]# groupadd dba

[root@DB12c ~]# groupadd oinstall

[root@DB12c ~]# useradd -g oinstall -G dba oracle

[root@DB12c ~]# su - oracle

[oracle@DB12c ~]$ echo $SHELL

/bin/bash

oracle@DB12c:/home/oracle>cat .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/products/12.1.0

export TNS_ADMIN=$ORACLE_HOME/network/admin

export ORACLE_SID=db12c

export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$ORACLE_BASE/products/crs/bin:.

echo -ne "\033]0;${USER}@${HOSTNAME%%.*}\007"

export PS1='${LOGNAME}@${HOSTNAME}:${PWD}>'

stty erase ^

8. 修改/etc/sysctl.conf文件参数

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048586

[root@DB12c ~]# /sbin/sysctl -p ----使修改参数立即生效

[root@DB12c ~]# /sbin/sysctl -a -----检查参数设置是否正确

9. 修改/etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

10.修改/etc/profile

if [ \$USER = "oracle" ]; then

if [ \$SHELL = "/bin/bash" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

umask 022

fi

11. 创建目录

[root@DB12c ~]# chown -R oracle:oinstall /u01/

[root@DB12c ~]# su - oracle

oracle@DB12c:/home/oracle>mkdir -p $ORACLE_BASE

oracle@DB12c:/home/oracle>mkdir -p $ORACLE_HOME

oracle@DB12c:/home/oracle>cd $ORACLE_HOME

oracle@DB12c:/u01/app/oracle/products/12.1.0>

12. 关闭防火墙及SELINUX

[root@DB12c ~]# service iptables stop

iptables: Flushing firewall rules: [ OK ]

iptables: Setting chains to policy ACCEPT: filter [ OK ]

iptables: Unloading modules: [ OK ]

[root@DB12c ~]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - No SELinux policy is loaded.

SELINUX=disable

# SELINUXTYPE= can take one of these two values:

# targeted - Targeted processes are protected,

# mls - Multi Level Security protection.

SELINUXTYPE=targeted

13 修改主机名解析

需要在/etc/hosts里面解析主机名，否则在安装的时候报错PRVF-0002错误

[root@DB12c ~]# cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.56.60 DB12c
