RAC e +Active d Dataguard n on Oracle
e Enterprise Linux(OEL 5 5.5 X86_64)
1 1 1 概述和说明
1 1.1 概述
本文档用于详细记录在 OEL 5.5 X86_64 位系统上 安装配置 e Oracle 11gR2(11.2.0.3.0)
RAC 的步骤、 RAC 数据库的基本维护、为 RAC 创建单实例 e Active l Physical Dataguard、
验证 e 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 VMware 公司的VMware ESXi Version 4.0 的虚拟主机，通过在该虚拟机
上配置两台 OEL 5.5 X86_64 位 Linux 系统的机器，然后在这两台 Linux 机器上配置 Oracle
11gR2 RAC 系统。其中，操作系统选择Oracle 公司的 OEL 5.5 X86_64 位 Linux 系统，数据
库软件采用目前 Oracle 11gR2 最新版本的11.2.0.3.0。
本文档中假定你已经安装配置好 VMware ESXi Version 4.0 的虚拟主机，如果没有该环
境的话，也可以通过自行安装 VMware Server 来完成 11gR2 RAC 的安装配置。
2 1.2 软件获取
操作系统： Oracle Enterprise Linux 5
Oracle 软件：Oracle 11g Release 2 (11.2) Software(64 bit)
虚拟机软件：VMware Server
其中，Oracle 软件可以通过上述连接直接获取版本为 11.2.0.1.0 的安装介质，或者通过
MetaLink 官方网站获取最新版本的 11.2.0.3.0 安装介质，其中 patch 编号为10404530。
2 2 2 安装前准备工作
1 2.1 配置虚拟机，安装 OEL 5 5.5 4 X86_64 位 位 x Linux 操作系统
这里，我们需要在 VMware ESXiVersion 4.0 的虚拟主机上创建两台虚拟机，其中每台
机器至少需要配置双网卡，一块网卡作为 Public，另一块作为 Private，建议 IP 地址均选择
手动配置，而不是 DHCP 动态分配，且要求指定的 IP 在网络里是唯一的。主机名也分别要
求指定为唯一，避免冲突。主机名、IP 地址在前期规划要慎重，一经指定，最好不要轻易
改变，避免一些不必要的麻烦。这里列出两台机器前期规划的主机名、IP 地址信息：

scan-cluster.localdomain scan-cluster SCAN IP 172.16.0.203 eth0
(Figure 2.1 网络配置信息表)
其中，每台机器至少需要配置 3 个 IP 地址，在安装操作系统的过程中，我们需要配置
公网 IP 和私有 IP 即可，虚拟 IP 在安装集群件时分配。Public IP、Virtual IP、SCANIP 必
须配置在同一网段。SCAN IP 是 Oracle 11g 新推出的，在配置 11g RAC 时需要指定。我们
的 SCAN IP 通过配置 DNS 服务器来实现，在下文中将给出配置步骤。

3 2.3 配置 S DNS 服务器，确认 SCAN IP 可以被解析
从 Oracle 11gR2 开始，引入 SCAN(Single Client Access Name) IP 的概念，相当于在客户
端和数据库之间增加一层虚拟的网络服务层，即是 SCAN IP 和 SCAP IP Listener。在客户端
的 tnsnames.ora 配置文件中，只需要配置SCAN IP 的配置信息即可，客户端通过 SCAN IP 、
SCAN IP Listener 来访问数据库。同之前各版本的 RAC 相比，使用 SCAN IP 的好处就是，
当后台 RAC 数据库添加、删除节点时，客户端配置信息无需修改。可以通过配置 DNS服
务器或 GNS 来配置 SCAN，我们这里以 DNS 为例来进行配置。

1 2.3.1 配置 DNS 服务器
这里，选择 IP 地址为 172.16.0.176的服务器来配置 DNS 服务器。
①安装 DNS 软件包：

[root@rdddns_rpm]#
② 配置/var/named/chroot/etc/named.conf 文件
先拷贝生成该文件：
[root@rdddns_rpm]#cd/var/named/chroot/etc/
[root@rddetc]#ll
total16
-rw-r--r--1rootroot 405Apr1807:50localtime

-rw-r-----1rootnamed 113Apr2314:55rndc.key
[root@rddetc]#cp-pnamed.caching-nameserver.confnamed.conf
[root@rddetc]#
修改后的该文件内容如下：

[root@rddetc]#
说明：为简单起见，将该文件中的 127.0.0.1、localhost 全部修改成any，且修改时，需
要注意左右两边留空格。修改部分在上述配置文件中以红色加粗标示。
通过拷贝来生成/var/named/chroot/etc/named.conf 文件时，注意加上-p 选项，来保证文
件的权限问题，否则会导致 DNS 服务启不来！
③ 配置 Zone 文件，修改/var/named/chroot/etc/named.rfc1912.zones 文件
配置 Zone 的目的是为了解析 SCANIP，在该文件末尾添加以下反向 Zone：
zone"0.16.172.in-addr.arpa."IN{
typemaster;
file"0.16.172.in-addr.arpa";
allow-update{none;};
};
配置反向 Zone 之后的该文件内容如下：
[root@rddetc]#pwd

[root@rddetc]#ll

};
e zone " "0.16.172.in-addr.arpa." N IN { {
e type master;
e file "0.16.172.in-addr.arpa";
e allow-update { { ; none; };
};
[root@rddetc]#
说明 ：正常情况下还应该配置正向 Zone 文件。这里，我们的 RAC 双节点 node1、node2
的 域 名 domain都 设 置 为 localdomain ， 而 默 认 情 况 下 ， 该 配 置 文 件
(/var/named/chroot/etc/named.rfc1912.zones)的第 15 行到第 20 行中已经自带下述正向 Zone 文
件配置信息，所以无需再添加。
zone"localdomain"IN{
typemaster;
file"localdomain.zone";
allow-update{none;};
};
④ 配置正、反向解析数据库文件。在/var/named/chroot/var/named路径下进行配置
首先，生成正、反向解析数据库文件。利用/var/named/chroot/var/named/localhost.zone
复制生成正向解析的数据库文件，利用/var/named/chroot/var/named/localhost.zone 复制生成
名为 0.16.172.in-addr.arpa 的反向解析的数据库文件。

说明： ：在上述步骤③中我们没有配置正向 Zone 文件，故只需生成反向解析数据库文件 ，
正向解析数据库文件利用默认的 localdomain.zone 文件。
生成的正、反向解析数据库文件名一定要同上述步骤③中定义的正、反向 Zone 文件一
致，否则 DNS 出错！
然后，定义正、反向解析数据库文件。
在正向解析数据库文件 localdomain.zone 末尾添加下述内容：
scan-cluster INA 172.16.0.203
添加后内容如下：
[root@rddnamed]#pwd
/var/named/chroot/var/named

2 2.3.2 测试 DNS 服务器解析 SCAN IP 正常
首先，在 DNS 服务器 172.16.0.176 上启动 DNS 服务：
[root@rddnamed]#/etc/init.d/namedstatus
rndc:connectfailed:127.0.0.1#953:connectionrefused

然后，分别在 RAC 节点 node1、node2 的/etc/resolv.conf 配置文件中添加下述配置信息：
searchlocaldomain
nameserver172.16.0.176
添加之后：
[root@node1~]#cat/etc/resolv.conf

最后，测试 SCAN IP 解析是否成功？

QQ:908601287 Http://www.cnblogs.com/flymaster500.cn
软件等同于 Oracle 10g 的 Clusterware 集群件。Oracle 建议以不同的用户分别安装 Grid
Infrastructure 软件、Oracle 数据库软件，我们这里以 grid 用户安装 Grid Infrastructure，oracle
用户安装 Oracle 数据库软件。并且 grid、oracle 用户需要属于不同的用户组。在配置 RAC
时，还要求这两个用户在 RAC 的不同节点上 uid、gid 要一致。用户、组的对应信息见下表：
p Group Name p Group ID p Group Info e Oracle User(1100) d Grid User(1101)
oinstall 1000 InventoryGroup Y Y
dba 1300 OSDBAGroup Y
oper 1301 OSOPER Group Y
asmadmin 1200 OSASM Y
asmdba 1201 OSDBAforASM Y Y
asmoper 1202 OSOPER forASM Y
(Figure 2.4 用户、组配置信息表)
我们可以通过执行下述 shell 脚本的 1preusers.sh 来完成用户、组的创建， 脚本的具

至此，Oracle 用户 SSH 对等性配置完成！重复上述步骤，以 grid 用户配置对等性。
3 2.13 配置共享磁盘
在任意节点上先创建共享磁盘，然后在另外的节点上选择添加已有磁盘。这里选择先在
node2 节点机器上创建共享磁盘，然后在 node1 上添加。共创建 4块硬盘，其中 2 块 500M
的硬盘，将来用于配置 GRIDDG 磁盘组，专门存放 OCR 和 Voting Disk；1块 3G 的磁盘，
用于配置DATA磁盘组，存放数据库；1 块 3G 的磁盘，用于配置 FLASH 磁盘组，用于闪
回区；
在 node2 上创建共享硬盘详细步骤：
① 先关闭节点 2 11gnode2，然后选择 11gnode2，右键选择编辑设置，Edit settings：
② 在编辑虚拟机对话框下，选择添加，Add,选择硬盘，Next：

⑦ 虚拟机属性中，选择刚才新添加的 SCSI controller1 驱动器，配置其为 Physical 模式 ，
用于支持共享，因为这块新添加的硬盘将来要被 node1、node2 两个节点访问：
⑧ 重复执行上述③--⑥步骤，添加第二块 500M 硬盘，将其驱动器设备选择 SCSI 1:1；
⑨ 如法炮制，添加另外两块 3G 硬盘，驱动器设备分别选择 SCSI 2:0，SCSI 2:1，同样
需要配置新添加的 SCSI controller 2 驱动器模式为 Physical 模式，用于支持共享。最后，添

至此，完成在两个节点上对共享硬盘的添加配置。
2.14 4 4 4 配置 ASM 磁盘
在上一步 2.13 节中，我们已经对 RAC 双节点已经配置好了共享磁盘，接下来需要将这
些共享磁盘格式化、然后用 asmlib 将其配置为 ASM 磁盘，用于将来存放 OCR、VotingDisk
和数据库用。
注意：只需在其中 1 个节点上格式化就可以，接下来我们选择在 node1 节点上格式化。
这里我们以 asmlib 软件来创建 ASM 磁盘，而不使用 raw disk，而且从 11gR2 开始，OUI
的图形界面已经不再支持 raw disk。
1 2.14.1 格式化共享磁盘
① 以 root 用户分别在两个节点上执行fdisk 命令，查看现有硬盘分区信息：

从上，我们可以看到目前两个节点上的分区信息一致：其中/dev/sda 是用于存放操作系

其次安装 oracleasm-2.6.18-194.el5-2.0.5-1.el5 软件包，最后安装 oracleasmlib-2.0.4-1.el5 软件
包。
安装完毕后，执行 rpm -qa|grep asm 确认是否安装成功。
3 2.14.3 配置 ASM r driver 服务
在 node1 上以 root 用户进行配置。在安装完上述步骤 2.14.2 节中的 3 个 ASM RPM 软
件 包 之 后 ， 可 以 通 过 执 行 /usr/sbin/oracleasm 命 令 来 进 行 配 置 ， 也 可 以 通 过 执 行
/etc/init.d/oracleasm 命令来进行配置，后者命令是Oracle 10g 中进行 ASM 配置的命令，Oracle
推荐执行前者命令，不过后者命令保留使用。
① 查看 ASM 服务状态：
[root@node1~]#/usr/sbin/oracleasmstatus
CheckingifASMisloaded:no
Checkingif/dev/oracleasmismounted:no
[root@node1~]#
看到，默认情况下 ASM 服务并未开启。具体命令和相关参数可以直接执行下述命令来
获取：

说明：/usr/sbin/oracleasm configure -i 命令进行配置时，用户配置为 grid，组为 asmadmin ，
启动 ASM library driver 驱动服务，并且将其配置为随着操作系统的启动而自动启动。
配置完成后，记得执行 /usr/sbin/oracleasm init 命令来加载 oracleasm 内核模块。
③ 在 node2 上执行上述步骤②，完成 ASM 服务配置。
2.14.4 4 4 4 配置 ASM 磁盘
我们安装 ASM RPM 软件包，配置 ASM 驱动服务的最终目的是要创建 ASM 磁盘，为
将来安装 grid 软件、创建 Oracle 数据库提供存储。
说明：只需在一个节点上创建 ASM 磁盘即可！创建完之后，在其它节点上执行
/usr/sbin/oracleasm scandisks 之后，就可看到 ASM 磁盘。
接下来，开始创建 ASM 磁盘：
① 执行/usr/sbin/oracleasm createdisk 来创建 ASM 磁盘

可以看到，数据库的安装文件 2.5G 大小，GRID 软件的安装 1.1GB。
为便于将来安装软件，分别将其 move 到 oracle 用户和 grid 用户的家目录：
[root@node1~]#mvdatabase//home/oracle/
[root@node1~]#mvgrid//home/grid/
[root@node1~]#
6 2.16 安装前预检查配置信息
在安装 GRID 之前，建议先利用 CVU(Cluster Verification Utility)检查 CRS 的安装前环
境。
① 使用CVU 检查CRS 的安装前环境：
[root@node1~]#su-grid
node1->pwd
/home/grid
node1->ls
Desktop grid
node1->cdgrid/

说明，节点 2无法将归档日志传递到备库。
原因：节点 2的 SYS 用户口令同备库的 SYS 口令不一致。
解决：调整节点 2的 SYS 用户口令，或者重新配置口令文件。
⑧备库开始应用日志：

至此，完成一次角色切换，即将新的备库（RAC 库）切换成主库，新的备库（单实例
库）又重新切换为物理备库，回到最初的状态！！！

3 13 补充说明与获取帮助
1 13.1 补充说明
文档说明：本实验文档是 Oracle 11gR2RAC+DG 的实验依据，所涉及内容较有难度、
相比较该实验应属于 Oracle 数据库领域高端的技术。因此对于 Oracle 数据库初学者而言，
有一定的难度和挑战，在完成本系列视频的学习和动手实验前，请务必认真阅读该文档！
软件说明：该系列实验的软件是目前Oracle 数据库的最新版本，11gR2 的 11.2.0.3.0 版
本，该软件需要 Metalink 账号才可以下载到，对于目前无法获取该软件（11.2.0.3.0 版本）
的学员，可以直接到 oracle 官网免费获取 11.2.0.1.0 的软件来完成该实验。
错误说明：在搭建 RAC 数据库的过程中，要注意准备工作充分，尤其是配置 ASM共
享存储那一部分、以及 grid/oracle 用户的权限和对等性问题。在配置物理备库的过程中，备
库恢复控制文件时，要在物理备库上查看你的 oracle 用户是否属于 asmadmin 用户组。
实验说明：在动手完成实验时，要遵循实验步骤，一次不成功，要反复多实验几次，出
现错误的过程中，注意查看错误信息和日志，定位错误原因，解决问题。
2 13.2 获取帮助
