1、概述和说明
1.1、概述
本文档用于详细记录在OEL6.3X86_64位系统上安装配置Oracle 11gR2(11.2.0.4.0)RAC的步骤、RAC数据库的基本维护、为RAC创建单实例Active Physical DataGuard、验证Active DataGuard的功能、RAC主库同单实例物理备库的角色转换等内容。
安装平台选择Oracle公司的Virtual Box虚拟机软件，通过在该虚拟机上配置两台OEL6.3 X86_64位Linux系统的机器，然后在这两台机器上配置Oracle11gR2RAC系统。其中
禁用selinux (将配置文件中SELINUX=enforcing修改为SELINUX=disabled) (注意：双节点都要执行)
[root@BJRAC ~]# more /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=enforcing # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted

>关闭防火墙 (注意：双节点都要执行)
[root@CQRAC ~]# set NLS=C
[root@CQRAC ~]# setup
进行设置即可.在这个界面中同样可以设置关闭其他的服务比如说ip6tables、iptables、sendmail等服务
>>关闭iptable服务之前，查看其状态
[root@BJRAC ~]# service iptables status Table: filter Chain INPUT (policy ACCEPT) num target prot opt source destination 1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 2 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 5 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) num target prot opt source destination 1 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain OUTPUT (policy ACCEPT) num target prot opt source destination
>>关闭iptable服务之后，可以查看状态
[root@CQRAC ~]# service iptables status
iptables: Firewall is not running.
>取消图形界面(注意：双节点都要执行)
因为Oracle Enterprise Linux6.3 X86_64为操作系统在安装时默认设置为字符界面，所以这里不需要再设置。

>配置/etc/hosts文件(注意：双节点都要执行)
[root@BJRAC ~]# more /etc/hosts 127.0.0.1 localhost ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 #BJRAC 192.168.1.150 BJRAC.localdomain BJRAC 192.168.1.152 BJRAC-VIP.localdomain BJRAC-VIP 192.168.56.150 BJRAC-PRIV.localdomain BJRAC-PRIV #CQRAC 192.168.1.160 CQRAC.localdomain CQRAC 192.68.1.162 CQRAC-VIP.localdomain CQRAC-VIP 192.168.56.160 CQRAC-PRIV.localdomain CQRAC-PRIV #SCAN-IP 192.168.1.203 SCAN-CLUSTER.localdomain SCAN-CLUSTER #RACDG 192.168.1.170 RACDG.localdomain RACDG
注意：要使两个节点中的/etc/hosts中的文件内容一致
2.3、配置DNS服务器，确认SCANIP可以被解析
2.10、停止NTP,11gR2新增的检查项
BJRAC节点
[root@BJRAC /]# service ntpd status ntpd is stopped [root@BJRAC /]# chkconfig ntpd off [root@BJRAC /]# mv /etc/ntp.conf /etc/ntp.conf.bak [root@BJRAC /]#
CQRAC节点
[root@CQRAC /]# service ntpd status ntpd is stopped [root@CQRAC /]# chkconfig ntpd off [root@CQRAC /]# mv /etc/ntp.conf /etc/ntp.conf.bak
2.12、配置oracle、grid用户SSH对等性

2.14.4、配置ASM磁盘
在节点BJRAC上创建ASM磁盘
