今天小麥苗給大家分享的是11gR2 RAC添加和刪除節點步驟。

11gR2 RAC添加和刪除節點步驟–刪除節點

一. 現有的RAC 節點的11.2.0.4，在本文檔中，我們要演示刪除一個節點：rac3所有刪除操作都在環境正常運行狀態下進行。

RAC 當前RAC 二. 在刪除節點前，建議手動備份OCR 每4），目的是如果出現某些問題，我們可以恢復OCR這裡在節點1用root執行手工OCR查看ocr三. DBCA調整service 如果RAC 的操作，並且待刪除節點的service 的，那麼在我們刪除該節點之前，需要把該節點上的連接轉移到其他節點上去，使用relocate service當preferred instance 會自動relocate的實例上，這個過程也可以手工來執行，命令如下：

將節點3轉移到其他節點，用oracle因為我這裡的3都是preferred只能從preferred。

–的信息，刪除節點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在節點1用戶運行dbca這裡可以用圖形界面來刪除：

dbca -> RAC database -> nstance Management -> Delete Instance -> 用戶和密碼 -> 也可以使用dbca 來操作：

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

上用Oracle 確認orcl3中清除

用戶執行，還要注意oracle 這裡已經沒有orcl3四. 層面刪除節點(Oracle 這小節的操作都用oracle 停止節點3用grid在節點3用戶更新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.

注意這的解決方法：

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，所以查看節點的oraInst.loc 修改節點3與節點1再次更新目錄，這次成功：

[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, 用戶執行Deinstall在節點1 用戶更新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）

用戶或者root查看節點都是unpinned在節點3用戶運行deconfig

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

6.2 在節點3清除家目錄：

rm -rf /u01/app/grid_home

rm -rf /home/oracle

七. 11gR2 添加節點分3（1到新節點，配置GRID，同時更新OCR信息。

）第二階段主要工作是複製RDBMS HOME信息。

）第三階段主要工作是DBCA表空間，redo log信息（包括註冊新的數據庫實例等）。

11gR2 步驟還是三個步驟。

刪除節點的過程中，原有的節點一直是online和ORACLE_HOME 注意事項：

）在添加/，在某些情況下添加/來解決問題。

）在正常安裝11.2 GRID界面提供SSH 沒有這個功能，因此需要手動配置oracle用戶的SSH用戶等效性。
