Oracle RAC增加一个节点_3个RAC节点的数据库

1、主机名规划:
#Public Network - (eth0)
192.168.110.11 rac1
192.168.110.12 rac2
192.168.110.13 rac3
#Private Interconnect - (eth1)
10.10.10.11 rac1priv
10.10.10.12 rac2priv
10.10.10.13 rac3priv
#Public Virtual IP (VIP) addresses - (eth0)
192.168.110.21 rac1vip
192.168.110.22 rac2vip
192.168.110.23 rac3vip

2、配置与rac1与rac2一样的OS环境,包括创建用户,环境变量,SSH验证等。

3、Install Oracle Clusterware on the new node
在第一个节点上操作以下:
cd $CRS_HOME/oui/bin
./addNode.sh
根据提示完成第3个节点的crs安装,安装完后成,运行以下脚本:
/oracle/app/oraInventory/orainstRoot.sh rac3
/oracle/app/crs/install/rootaddnode.sh rac1
/oracle/app/crs/root.sh rac3
详细日志如下:
[root@rac3 ~]# /oracle/app/oraInventory/orainstRoot.sh
Changing permissions of /oracle/app/oraInventory to 770.
Changing groupname of /oracle/app/oraInventory to oinstall.
The execution of the script. is complete

4、
[oracle@rac1 ~]$ cat $CRS_HOME/opmn/conf/ons.config
localport=6113
remoteport=6200
loglevel=3
useocr=on
[oracle@rac1 ~]$ $CRS_HOME/bin/racgons add_config rac3:6200

[oracle@rac3 ~]$ olsnodes
rac1
rac2
rac3

操作后,状态如下:
[oracle@rac1 ~]$ crs_stat -t
Name Type Target State Host
------------------------------------------------------------
ora....SM1.asm application OFFLINE OFFLINE
ora....C1.lsnr application ONLINE ONLINE rac1
ora.rac1.gsd application ONLINE ONLINE rac1
ora.rac1.ons application ONLINE ONLINE rac1
ora.rac1.vip application ONLINE ONLINE rac1
ora....SM2.asm application OFFLINE OFFLINE

5、Install Oracle RDBMS and ASM Home on the new node
在第一个节点上操作以下:
cd $ORACLE_HOME/oui/bin
./addNode.sh
完成后,执行:
/oracle/app/product/10.2.0/db_1/root.sh rac3
6、Configure the Listener on the new Node
The following steps need to be done on node3:
$ORACLE_HOME/bin/netca
只选择rac3进行配置

6、Create an ASM Instance on the new node.
The following steps need to be done on node1:
Login as the Oracle user and set the environment to ASM home.
$ORACLE_HOME/bin/dbca
先配ASM,再建INSTANCE
选择instance management-------add instance
创建完成后,状态如下:
[oracle@rac3 admin]$ crs_stat -t
Name Type Target State Host
