删除节点
1、关闭二节点监听
[oracle@rac1 dbs]$ srvctl disable listener -l LISTENER -n rac2
[oracle@rac1 dbs]$ srvctl stop listener -l LISTENER -n rac2
2、关闭二节点实例
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
3、disable 二节点
SQL> ALTER DATABASE DISABLE THREAD 2;
Database altered.
4、更新一节点inentory
[oracle@rac1 dbs]$ /oracle/app/oracle/product/11.2.0/dbhome_1/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/oracle/app/oracle/product/11.2.0/dbhome_1 "CLUSTER_NODES=rac1"
Starting Oracle Universal Installer...

The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /oracle/app/oraInventory
'UpdateNodeList' was successful.
[oracle@rac1 dbs]$
5、确认unpinned
[grid@rac1 ~]$ olsnodes -s -t
rac1 Active Unpinned
rac2 Active Unpinned
[grid@rac1 ~]$
6、删除二节点grid配置信息
[root@rac2 ~]# /oracle/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -deinstall -force

[grid@rac1 ~]$
添加节点
1、预检查中ntp的问题可以忽略，其他问题请确认
cluvfy stage -pre nodeadd -n rac2 -verbos
2、添加grid
export IGNORE_PREADDNODE_CHECKS=Y

WARNING:A new inventory has been created on one or more nodes in this session. However, it has not yet been registered as the central inventory of this system.
To register the new inventory please run the script at '/oracle/app/oraInventory/orainstRoot.sh' with root privileges on nodes 'rac2'.
If you do not register the inventory, you may not be able to update or patch the products you installed.
The following configuration scripts need to be executed as the "root" user in each new cluster node. Each script in the list below is followed by a list of nodes.
/oracle/app/oraInventory/orainstRoot.sh #On nodes rac2
/oracle/app/11.2.0/grid/root.sh #On nodes rac2
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts in each cluster node

cluvfy stage -post nodeadd -n rac2
4、添加rdbms
/oracle/app/oracle/product/11.2.0/dbhome_1/oui/bin/addNode.sh "CLUSTER_NEW_NODES={rac2}"
5、二节点instance启动
5.1创建二节点redolog
alter database add logfile thread 2 group 3 '+DATA/orcl/redo03.log' size 50m reuse;
alter database add logfile thread 2 group 4 '+DATA/orcl/redo04.log' size 50m reuse;
5.2创建UNDO2

Tablespace created.
5.3enable 二节点

5.4一节点创建pfile
SQL> create pfile='/home/oracle/initorcl.ora' from spfile;
File created.
SQL> shutdown immediate

SQL> exit
5.5修改spfile

修改pfile。添加

两个节点pfile启动看看
SQL> startup pfile='/home/oracle/initorcl.ora';
ORACLE instance started.

Database Buffers 50331648 bytes

Database mounted.
Database opened.
然后创建spfile
SQL> create spfile='+DATA/orcl/spfileorcl.ora' from pfile='/home/oracle/initorcl.ora';
File created.
遇到的问题：
1、二节点添加集群失败
[grid@rac1 ~]$ /oracle/app/11.2.0/grid/oui/bin/addNode.sh "CLUSTER_NEW_NODES={rac2}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac2-vip}"

SEVERE:Error ocurred while retrieving node numbers of the existing nodes. Please check if clusterware home is properly configured.
第一次添加失败后新的节点信息已经写入了inventory
更新一节点inventory后继续
[grid@rac1 ~]$ /oracle/app/11.2.0/grid/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/oracle/app/11.2.0/grid "CLUSTER_NODES=rac1" CRS=TRUE -silent

The inventory is located at /oracle/app/oraInventory

说明：以上步骤为快捷版，并没有删除二节点grid和oracle的步骤。非官方文档步骤。如果删除的二节点还要继续使用（如做添加试验），请分别删除grid用户和oracle用户$ORACLE_BASE下的内容，并删除/etc面ora开头的目录和文件，如cd /etc，rm -rf ora*
