今天小麦苗给大家分享的是11gR2 RAC添加和删除节点步骤。

11gR2 RAC添加和删除节点步骤–删除节点

一. 现有的RAC 节点的11.2.0.4，在本文档中，我们要演示删除一个节点：rac3所有删除操作都在环境正常运行状态下进行。

RAC 当前RAC 二. 在删除节点前，建议手动备份OCR 每4），目的是如果出现某些问题，我们可以恢复OCR这里在节点1用root执行手工OCR查看ocr三. DBCA调整service 如果RAC 的操作，并且待删除节点的service 的，那么在我们删除该节点之前，需要把该节点上的连接转移到其他节点上去，使用relocate service当preferred instance 会自动relocate的实例上，这个过程也可以手工来执行，命令如下：

将节点3转移到其他节点，用oracle因为我这里的3都是preferred只能从preferred。

–的信息，删除节点3：

[oracle@rac1 ~]$ srvctl stop service -d orcl -s orcl_taf -i orcl3

[oracle@rac1 ~]$ srvctl status service -d orcl

Service orcl_taf is running on instance(s) orcl1,orcl2

[oracle@rac1 ~]$ srvctl modify service -d orcl -s orcl_taf -n -i orcl1,orcl2 -f

[oracle@rac1 ~]$ srvctl status service -d orcl

Service orcl_taf is running on instance(s) orcl1,orcl2

[oracle@rac1 ~]$ srvctl config service -d orcl

Service name: orcl_taf

Service is enabled

Server pool: orcl_orcl_taf

Cardinality: 2

Disconnect: true

Service role: PRIMARY

Management policy: AUTOMATIC

DTP transaction: false

AQ HA notifications: false

Failover type: SELECT

Failover method: BASIC

TAF failover retries: 180

TAF failover delay: 5

Connection Load Balancing Goal: LONG

Runtime Load Balancing Goal: NONE

TAF policy specification: BASIC

Edition:

Preferred instances: orcl1,orcl2

Available instances:

3.2 DBCA在节点1用户运行dbca这里可以用图形界面来删除：

dbca -> RAC database -> nstance Management -> Delete Instance -> 用户和密码 -> 也可以使用dbca 来操作：

dbca -silent -deleteInstance [-nodeList node_name] -gdbName gdb_name -instanceName instance_name -sysDBAUserName sysdba -sysDBAPassword password

上用Oracle 确认orcl3中清除

用户执行，还要注意oracle 这里已经没有orcl3四. 层面删除节点(Oracle 这小节的操作都用oracle 停止节点3用grid在节点3用户更新Inventory

[root@rac3 ~]# su – oracle

[oracle@rac3 ~]$ cd $ORACLE_HOME/oui/bin

[oracle@rac3 bin]$ ls

addLangs.sh attachHome.sh filesList.bat filesList.sh resource runInstaller runSSHSetup.sh

addNode.sh detachHome.sh filesList.properties lsnodes runConfig.sh runInstaller.sh

[oracle@rac3 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 "CLUSTER_NODES=rac3"

Starting Oracle Universal Installer…

Checking swap space: must be greater than 500 MB. Actual 2047 MB Passed

The inventory pointer is located at /etc/oraInst.loc

The inventory is located at /u01/app/oraInventory

'UpdateNodeList' was successful.

注意这的解决方法：

log查看：/etc/oraInst.loc

[root@rac3 logs]# cat /etc/oraInst.loc

inventory_loc=/u01/app/oraInventory

inst_group=oinstall

[root@rac3 logs]#

–上操作的，所以查看节点的oraInst.loc 修改节点3与节点1再次更新目录，这次成功：

[oracle@rac3 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/u01/app/oracle/11.2.0/db_1 "CLUSTER_NODES=rac3"

Starting Oracle Universal Installer…

Checking swap space: must be greater than 500 MB. Actual 2925 MB Passed

The inventory pointer is located at /etc/oraInst.loc

The inventory is located at /u01/oraInventory

'UpdateNodeList' was successful.

4.3 的ORACLE_HOME, 用户执行Deinstall在节点1 用户更新inventory

[root@rac1 ~]# su – oracle

[oracle@rac1 ~]$ $ORACLE_HOME/oui/bin/runInstaller -updateNodeList ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 "CLUSTER_NODES=rac1,rac2"

Starting Oracle Universal Installer…

Checking swap space: must be greater than 500 MB. Actual 1868 MB Passed

The inventory pointer is located at /etc/oraInst.loc

The inventory is located at /u01/app/oraInventory

'UpdateNodeList' was successful.

在GRID）

用户或者root查看节点都是unpinned在节点3用户运行deconfig

[root@rac3 ~]# /u01/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig -deinstall -force

6.2 在节点3清除家目录：

rm -rf /u01/app/grid_home

rm -rf /home/oracle

七. 11gR2 添加节点分3（1到新节点，配置GRID，同时更新OCR信息。

）第二阶段主要工作是复制RDBMS HOME信息。

）第三阶段主要工作是DBCA表空间，redo log信息（包括注册新的数据库实例等）。

11gR2 步骤还是三个步骤。

删除节点的过程中，原有的节点一直是online和ORACLE_HOME 注意事项：

）在添加/，在某些情况下添加/来解决问题。

）在正常安装11.2 GRID界面提供SSH 没有这个功能，因此需要手动配置oracle用户的SSH用户等效性。
