Oracle RAC下删除节点

左手的ㄟ右手 2022-09-30 07:31 338阅读 0赞

**1.测试环境：**

OS:Centos 6.8

Oralce:11.2.0.4

3节点RAC，主机名是rac1,rac2,rac3 现在需要删除rac3

3个节点实例均正常运行，在线删除节点

**2.节点确认**

登陆任一节点，执行

SQL> select thread\#,status,instance from v$thread;  
  
  
   THREAD\# STATUS  
\---------- ------  
INSTANCE  
\--------------------------------------------------------------------------------  
1 OPEN  
rac1  
  
  
2 OPEN  
rac2  
  
  
3 OPEN  
rac3  
  
说明3个节点，实例名是rac1,rac2,rac3

rac1:/u01/app/11.2.0/grid\_1/bin@rac1>./olsnodes -t -s  
rac1Active Unpinned  
rac2Active Unpinned  
rac3Active Unpinned

**3.在所有保留节点（rac1，rac2）上执行**

\[root@rac1 ~\]\# cd /u01/app/11.2.0/grid\_1/bin/  
\[root@rac1 bin\]\# ./crsctl unpin css -n rac3  
CRS-4667: Node rac3 successfully unpinned.

\[root@rac2 ~\]\# cd /u01/app/11.2.0/grid\_1/bin/  
\[root@rac2 bin\]\# ./crsctl unpin css -n rac3  
CRS-4667: Node rac3 successfully unpinned.

**4.使用dbca删除rac3实例**

注意这里需要在任一保留节点上删除rac3实例，也就是必须在rac1或rac2上执行

![Center][]

![Center 1][]

![Center 2][]

![Center 3][]

![Center 4][]

![Center 5][]

![Center 6][]

![Center 7][]

![Center 8][]

![Center 9][]

**5.验证rac3实例已被删除**

查看活动的实例：

SQL> select thread\#,status,instance from v$thread;  
  
  
   THREAD\# STATUS  
\---------- ------  
INSTANCE  
\--------------------------------------------------------------------------------  
1 OPEN  
rac1  
  
  
2 OPEN

rac2

//已经没有rac3

rac3:/home/oracle@rac3>ps -ef|grep ora\_  
oracle    7550 30915  0 14:17 pts/0    00:00:00 grep ora\_

//rac3的oracle进程已经消失

**查看库的配置**

rac1:/home/oracle@rac1>srvctl config database -d rac  
Database unique name: rac  
Database name: rac  
Oracle home: /u01/app/oracle/product/11.2.0/db\_1  
Oracle user: oracle  
Spfile: +DATA/rac/spfilerac.ora  
Domain:   
Start options: open  
Stop options: immediate  
Database role: PRIMARY  
Management policy: AUTOMATIC  
Server pools: rac  
Database instances: rac1,rac2  
Disk Groups: DATA,FRA\_ARC  
Mount point paths:   
Services:   
Type: RAC  
Database is administrator managed

**6.停止rac3节点的监听**

rac3:/home/oracle@rac3>srvctl config listener -a  
Name: LISTENER  
Network: 1, Owner: grid  
Home: <CRS home>  
  /u01/app/11.2.0/grid\_1 on node(s) rac3,rac1,rac2  
End points: TCP:1521

rac3:/home/oracle@rac3>srvctl disable listener -l listener -n rac3  
rac3:/home/oracle@rac3>srvctl stop listener -l listener -n rac3  
rac3:/home/oracle@rac3>lsnrctl status

 TNS-12560: TNS:protocol adapter error  
  TNS-00511: No listener  
   Linux Error: 111: Connection refused

//rac3监听已停止，rac1和rac2监听还在

**7.在rac3节点使用oracle用户更新集群列表**

rac3:/home/oracle@rac3>/u01/app/oracle/product/11.2.0/db\_1/oui/bin/runInstaller -updateNodeList ORACLE\_HOME=$ORACLE\_HOME "CLUSTER\_NODES=\{rac3\}" -local

执行完后，rac3的$ORACLE\_HOME目录里的文件已被删除

**9.在任一保留的节点上停止rac3节点NodeApps**

rac1:/home/oracle@rac1>srvctl stop nodeapps -n rac3 -f  //发现rac3的ons和vip 已经停了

**10.在每个保留节点上执行**

此时rac3的cluster 进程已被停止

**12.删除rac3节点的vip**

如果上一步执行顺利的话，rac3节点的vip此时已被删除，在任一保留节点执行crs\_stat -t 验证一下

如果仍有rac3节点的vip 服务哎，执行如下:

rac1:/home/oracle@rac1>srvctl stop vip -i ora.rac3.vip -f

rac1:/home/oracle@rac1>srvctl remove vip -i ora.rac3.vip -f

\[root@rac1 ~\]\# crsctl delete resource ora.rac3.vip -f

**13.在任一保留的节点上删除rac3节点**

\[root@rac1 bin\]\# cd /u01/app/11.2.0/grid\_1/bin/

**14.rac3节点使用grid 用户更新集群列表**
