删除RAC集群节点
删除GRID集群节点：参考oracle database 11g RAC手册（第二版）
目前GRID集群中节点信息：
[grid@node1 ~]$ olsnodes
node1
node2
node3
node4
node5
node6
目标删除node3、node4节点，保留GI集群4个节点工作。
1、检查当前集群服务运行状态
[grid@node1 ~]$ crsctl status resource -t

2、从集群中删除node3、node4节点（没有启用GNS服务）
（1）在node1上，以root身份，运行如下命令，终止node3、node4节点的使用：
[root@node1 ~]# cd /u01/app/11.2.0.4/grid/bin/
[root@node1 bin]# ./crsctl unpin css -n node3
CRS-4667: Node node3 successfully unpinned.
[root@node1 bin]# ./crsctl unpin css -n node4
CRS-4667: Node node4 successfully unpinned.
（2）以root身份，在node3、node4节点上运行$GRID_HOME/crs/install目录下的rootcrs.pl脚本，已禁用集群资源。
[root@node3 ~]# cd /u01/app/11.2.0.4/grid/crs/install/
[root@node3 install]# ./rootcrs.pl -deconfig -force
[root@node4 ~]# cd /u01/app/11.2.0.4/grid/crs/install/
[root@node4 install]# ./rootcrs.pl -deconfig -force
[grid@node1 ~]$ crsctl status res -t

[grid@node1 ~]$
（3）以root用户，在node1上执行一下命令（11.2.0.4->可省略）：
[root@node1 ~]# cd /u01/app/11.2.0.4/grid/bin/
[root@node1 bin]# ./crsctl delete node -n node3
CRS-4661: Node node3 successfully deleted.
[root@node1 bin]# ./crsctl delete node -n node4
CRS-4661: Node node4 successfully deleted.
（4）以软件拥有者身份，执行以下命令，以更新oracle inventory：
[grid@node3 bin]$ pwd
/u01/app/11.2.0.4/grid/oui/bin
[grid@node3 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/11.2.0.4/grid "CLUSTER_NODES={node3}" CRS=TRUE -local
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500 MB. Actual 16386 MB Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oraInventory
'UpdateNodeList' was successful.
[grid@node4 bin]$ pwd
/u01/app/11.2.0.4/grid/oui/bin
[grid@node4 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/11.2.0.4/grid "CLUSTER_NODES={node4}" CRS=TRUE -local
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500 MB. Actual 16386 MB Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oraInventory
'UpdateNodeList' was successful.
（5）在node3、node4节点上，以软件拥有者身份，执行以下命令，删除oracle网格主目录：
[grid@node3 ~]$ cd /u01/app/11.2.0.4/grid/deinstall/
[grid@node3 deinstall]$ ./deinstall -local
[grid@node4 ~]$ cd /u01/app/11.2.0.4/grid/deinstall/
[grid@node4 deinstall]$ ./deinstall -local
（6）在其他节点上，以软件拥有者身份，执行以下命令，更新剩余所有节点上的oracle inventory目录：
[grid@node1 bin]$ pwd
/u01/app/11.2.0.4/grid/oui/bin
[grid@node1 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/11.2.0.4/grid "CLUSTER_NODES={node1,node2,node5,node6}" CRS=TRUE
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500 MB. Actual 15673 MB Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /u01/app/oraInventory
'UpdateNodeList' was successful.
（7）验证卸载情况：
[grid@node1 bin]$ cluvfy stage -post nodedel -n node_list[-verbose]
Performing post-checks for node removal
Checking CRS integrity...
Clusterware version consistency passed
CRS integrity check passed
Node removal check passed
Post-check for node removal was successful.
[grid@node1 bin]$ olsnodes
node1
node2
node5
node6
3)扩展ltdb数据库从2个节点（node1、node2）到4个节点（node1、node2、node5、node6）：
[oracle@node1 ~]$ srvctl config database -d ltdb
Database unique name: ltdb
Database name: ltdb
Oracle home: /u01/app/oracle/product/11.2.0.4/dbhome_1
Oracle user: oracle
Spfile: +ORADG/ltdb/spfileltdb.ora
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: ltdb
Database instances: ltdb1,ltdb2
Disk Groups: ORADG,FLASH
Mount point paths:
Services:
Type: RAC
Database is administrator managed
[oracle@node1 ~]$ srvctl status database -d ltdb
Instance ltdb1 is running on node node1
Instance ltdb2 is running on node node2
dbca-->instance managerment-->add isntance 添加实例
------------------------操作过程中遇到的错误---------------------------------
[grid@node1 ~]$ srvctl add instance -d ltdb -i ltdb5 -n node5
PRCD-1051 : Failed to add instance to database ltdb
PRCS-1011 : Failed to modify server pool ltdb
PRCS-1014 : Server node5 is already part of server pool ltdb
[grid@node1 ~]$ crsctl status serverpool -p
NAME=ora.ltdb
IMPORTANCE=1
MIN_SIZE=0
MAX_SIZE=-1
SERVER_NAMES=node1 node2 node5 node6
PARENT_POOLS=Generic
EXCLUSIVE_POOLS=
ACL=owner:oracle:rwx,pgrp:oinstall:rwx,other::r--
目前数据库正在做测试，这个问题后续解决。
