目标：
当前我环境中是有两个节点RAC1和RAC2 节点。如今添加一个RAC3节点。
概要：为现有的Oracle10g RAC 加入节点大致包含下面步骤:
1. 配置新的server节点上的硬件及操作系统环境
2. 向 Cluster 集群中增加该节点
3. 在新节点上安装 Oracle Database software
4. 为新的节点配置监听器 LISTENER
5. 通过 DBCA 为新的节点加入实例
注意：在新的server节点上配置操作系统环境
1. 这包含配置该节点今后使用的 public network 公用网络和 private network 接口，不要忘记在 hosts 文件里增加之前节点的网络信息。并将该份完整的hosts 文件传到集群Cluster 中已有的节点上，保证处处能够訪问。
2. 同一时候须要在原有的基础上配置 oracle(或其它DBA)用户的身份等价性。这须要将新节点上生成的 id_rsa.pub 和id_dsa.pub 文件里的信息追加到authorized_keys 文件里，并保证在全部节点上均有这样一份同样的authorized_keys 文件。
3. 调整新节点上的操作系统内核參数。保证其满足今后在该节点上执行实例的内存要求以及 10g RAC Cluster 的推荐的udp网络參数。
4. 调整新节点上的系统时间以保持同其它节点一致，或者配置NTP 服务。
5. 保证原有 Cluster 中全部节点上的CRS 都正常执行，否则addNode时会报错。
6. 配置 clusterware 和database 软件的安装文件夹，要求路径和原有节点上的一致。
一． 准备工作
1. 查看当前RAC环境版本号和状态

2. 配置节点3
[root@rac3 ~]# hostname

[root@rac3 ~]# id oracle
uid=54321(oracle) gid=54321(oinstall)groups=54321(oinstall),54322(dba)

3. 配置三个节点/etc/hosts映射
注意：三个节点都要配置！。！
[root@rac3 ~]# vi /etc/hosts
# Do not remove the following line, or variousprograms
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.90.2 rac1
192.168.90.5 rac2
192.168.91.3 rac1-priv
192.168.91.6 rac2-priv
192.168.90.3 rac1-vip
192.168.90.4 rac2-vip
#=========add node rac3==========#
192.168.90.10 rac3
192.168.91.11 rac3-priv
192.168.90.7 rac3-vip
检查网络是否通畅：
[root@rac3 ~]# ping rac1
PING rac1 (192.168.90.2) 56(84) bytes of data.
64 bytes from rac1 (192.168.90.2): icmp_seq=1ttl=64 time=0.614 ms
64 bytes from rac1 (192.168.90.2): icmp_seq=2ttl=64 time=0.169 ms
--- rac1 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss,time 1000ms
rtt min/avg/max/mdev = 0.169/0.391/0.614/0.223 ms
4. 配置OS级别 内核參数
这里显示的都是要加入的參数，原来的都不要动！！
。
[root@rac3 ~]# cat /etc/sysctl.conf
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
/sbin/sysctl –p 生效一下
[root@rac3 ~]# cat /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
[root@rac3 ~]# cat /etc/pam.d/login
session required pam_selinux.so open
[root@rac3 ~]# cat /etc/profile
if [ $USER = oracle ]; then
if [ $SHELL = /bin/ksh ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
5. 检查所须要的rpm是否都在,没有的话详细安装
[root@rac3 ~]# rpm -q binutils compat-dbcontrol-center gcc gcc-c++ glibc glibc-common libstdc++ libstdc++-devel make
binutils-2.17.50.0.6-14.el5
compat-db-4.2.52-5.1
control-center-2.16.0-16.el5
gcc-4.1.2-50.el5
gcc-c++-4.1.2-50.el5
glibc-2.5-58
glibc-common-2.5-58
libstdc++-4.1.2-50.el5
libstdc++-devel-4.1.2-50.el5
make-3.81-3.el5
二． 開始配置Openfiler存储
用节点3打开火狐配置：
配置略。
。。
就是加了一个rac3的MAPPING
2.1 在节点3上发现存储 假设没有返回值 重新启动一下Linux
[root@rac3 ~]# iscsiadm --mode discoverydb --typesendtargets --portal 192.168.90.8 --discover
192.168.90.8:3260,1 rac3
[root@rac3 ~]#
[root@rac3 ~]#
[root@rac3 ~]# iscsiadm --mode node --targetnamerac3 192.168.90.10:3260 --login
Logging in to [iface: default, target: rac3,portal: 192.168.90.8,3260]
Login to [iface: default, target: rac3, portal:192.168.90.8,3260] successful.
2.2 配置开机启动规则
[root@rac3 ~]# cat /etc/udev/rules.d/60-raw.rules
# Enter raw device bindings here.
#
# An example would be:
# ACTION=="add", KERNEL=="sda", RUN+="/bin/raw/dev/raw/raw1 %N"
# to bind /dev/raw/raw1 to /dev/sda, or
# ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
# to bind /dev/raw/raw2 to the device with major 8,minor 1.
ACTION=="add",KERNEL=="/dev/sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="17", RUN+="/bin/raw /dev/raw/raw1 %M %m"
ACTION=="add",KERNEL=="/dev/sdc1", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="33", RUN+="/bin/raw /dev/raw/raw2 %M %m"
ACTION=="add",KERNEL=="/dev/sdd1", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="49", RUN+="/bin/raw /dev/raw/raw3 %M %m"
ACTION=="add",KERNEL=="/dev/sde1", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="65", RUN+="/bin/raw /dev/raw/raw4 %M %m"
ACTION=="add",KERNEL=="/dev/sdf1", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", ENV{MAJOR}=="8",ENV{MINOR}=="81", RUN+="/bin/raw /dev/raw/raw5 %M %m"
KERNEL=="raw[1-5]",OWNER="oracle", GROUP="oinstall", MODE="640"
使之生效
[root@rac3 ~]# start_udev
Starting udev: [ OK ]
三． 创建对应文件夹，配置环境变量，配置互信
3.1 创建文件夹
[root@rac3 ~]# mkdir -p /u01/app/oracle
[root@rac3 ~]# chown oracle:oinstall -R /u01/
[root@rac3 ~]# ll /u01/
total 4
drwxr-xr-x 3 oracle oinstall 4096 Aug 26 12:28 app
3.2 配置环境变量
[oracle@rac3 ~]$ 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=$ORACLE_BASE/product/10.2.0/db_2
export CRS_HOME=$ORACLE_BASE/product/10.2.0/db_1
export PATH=$PATH:$CRS_HOME/bin:$ORACLE_HOME/bin
[oracle@rac3 ~]$ . .bash_profile
3.3 配置互信
[oracle@rac3 ~]$ ssh-keygen

在master节点的cssd.log中有具体信息
五． 为新节点安装数据库软件：($ORACLE_HOME/oui/bin)
[oracle@rac1 ~]$ cd/u01/app/oracle/product/10.2.0/db_2/oui/bin/
[oracle@rac1 bin]$ ls
addLangs.sh addNode.sh lsnodes ouica.sh resource runConfig.sh runInstaller runInstaller.sh
[oracle@rac1 bin]$ ./addNode.sh
Starting Oracle Universal Installer...
No pre-requisite checks found in oraparam.ini, nosystem pre-requisite checks will be executed.
Oracle Universal Installer, Version 10.2.0.1.0Production
Copyright (C) 1999, 2005, Oracle. All rightsreserved.
相同一个summary 開始安装
节点3：
[root@rac3 ~]#/u01/app/oracle/product/10.2.0/db_2/root.sh
Running Oracle10 root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/10.2.0/db_2
Enter the full pathname of the local bin directory:[/usr/local/bin]:
The file "dbhome" already exists in/usr/local/bin. Overwrite it? (y/n)
[n]:
The file "oraenv" already exists in/usr/local/bin. Overwrite it? (y/n)
[n]:
The file "coraenv" already exists in/usr/local/bin. Overwrite it?
(y/n)
[n]:
Entries will be added to the /etc/oratab file asneeded by
Database Configuration Assistant when a database iscreated
Finished running generic part of root.sh script.
Now product-specific root actions will beperformed.
此时的nodeapps已经加入成功。如今加入Listener和instance
[root@rac1 bin]# ./crs_stat -t

选择 reconfigure
六． 将新节点实例增加集群（$ORACLE_HOME/bin/dbca）
在原有节点运行
[oracle@rac1]# dbca
在节点RAC3上添加ASM
是否运行其它操作这里NO!!!!
查看节点配置：
[root@rac3 bin]# ./crs_stat -t
