Oracle 10203 RAC環境添加新節點（二） CLUSTER軟體的建立

簡單描述一下，在Oracle 10203 for Solaris sparc的RAC雙節點環境中，新增一個節點的過程。共用儲存已經在第三個節點上配置完成，這裡主要介紹作業系統上和Oracle上的配置。

這一篇描述CLUSTER軟體的建立。

在新增節點racnode3上將共用儲存上的裸裝置授權給Oracle使用者：

bash-3.00# chown oracle:oinstall /dev/rdsk/c1t500601603022E66Ad*

建立和節點1、節點2上一致的/dev/rac/vot和/dev/rac/ocr連結，執行相同的裸裝置檔案：

bash-3.00# mkdir /dev/rac

bash-3.00# ln -s /dev/rdsk/c1t500601603022E66Ad2s1 /dev/rac/ocr

bash-3.00# ln -s /dev/rdsk/c1t500601603022E66Ad2s3 /dev/rac/vot

在安裝節點執行$ORA_CLS_HOME/out/bin/addNode.sh來啟動圖形化介面添加新的節點：

bash-2.03$ ./addNode.sh

All installer requirements met.

Oracle Universal Installer, Version 10.2.0.1.0 Production

在圖形介面中，填入新增節點的PUBLIC、PRIVATE和VIP對應的名稱。

安裝過程Oracle跳過了一些遠端執行碰到的錯誤，需要手工更正，在racnode3上執行下面的指令碼：

bash-3.00$ /data/oracle/product/10.2/crs/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/data/oracle/product/10.2/crs ORACLE_HOME_NAME=OraCrs10g_home1 CLUSTER_NODES=racnode1,racnode2,racnode3 CRS=true "INVENTORY_LOCATION=/data/oracle/oraInventory" LOCAL_NODE=racnode3

Starting Oracle Universal Installer...

Checking installer requirements...

Checking operating system version: must be 5.8, 5.9 or 5.10.    Actual 5.10

 Passed

Checking Temp space: must be greater than 250 MB.   Actual 10167 MB    Passed

Checking swap space: must be greater than 500 MB.   Actual 7415 MB    Passed

All installer requirements met.

'AttachHome' was successful.

在節點2上執行下面的指令碼：

bash-2.03$ /data/oracle/product/10.2/crs/oui/bin/runInstaller -updateNodeList -noClusterEnabled ORACLE_HOME=/data/oracle/product/10.2/crs CLUSTER_NODES=racnode1,racnode2,racnode3 CRS=true "INVENTROY_LOCATION=/data/oracle/oraInventory" LOCAL_NODE=racnode2

Starting Oracle Universal Installer...

Checking installer requirements...

Checking operating system version: must be 5.8, 5.9 or 5.10.    Actual 5.8

 Passed

Checking Temp space: must be greater than 150 MB.   Actual 8233 MB    Passed

Checking monitor: must be configured to display at least 256 colors.    Actual 16777216    Passed

All installer requirements met.

'UpdateNodeList' was successful.

節點3上運行類似的指令碼：

bash-3.00$ /data/oracle/product/10.2/crs/oui/bin/runInstaller -updateNodeList -noClusterEnabled ORACLE_HOME=/data/oracle/product/10.2/crs CLUSTER_NODES=racnode1,racnode2,racnode3 CRS=true "INVENTROY_LOCATION=/data/oracle/oraInventory" LOCAL_NODE=racnode3

Starting Oracle Universal Installer...

Checking installer requirements...

Checking operating system version: must be 5.8, 5.9 or 5.10.    Actual 5.10

 Passed

Checking Temp space: must be greater than 250 MB.   Actual 10167 MB    Passed

Checking swap space: must be greater than 500 MB.   Actual 7415 MB    Passed

Checking monitor: must be configured to display at least 256 colors.    Actual 16777216    Passed

All installer requirements met.

'UpdateNodeList' was successful.

隨後需要依次執行下面的指令碼：

1.節點3上的/data/oracle/oraInventory/orainstRoot.sh：

bash-3.00# ./data/oracle/oraInventory/orainstRoot.sh

Creating the Oracle inventory pointer file (/var/opt/oracle/oraInst.loc)

Changing permissions of /data/oracle/oraInventory to 770.

Changing groupname of /data/oracle/oraInventory to oinstall.

The execution of the script. is complete

2.節點1上的/data/oracle/product/10.2/crs/install/rootaddnode.sh：

# ./data/oracle/product/10.2/crs/install/rootaddnode.sh

clscfg: EXISTING configuration version 3 detected.

clscfg: version 3 is10GRelease 2.

Attempting to add 1 new nodes to the configuration

Using ports: CSS=49895 CRS=49896 EVMC=49898 and EVMR=49897.

node <nodenumber>: <nodename> <private interconnect name> <hostname>

node 3: racnode3 racnode3-priv racnode3

Creating OCR keys for user 'root', privgrp 'other'..

Operation successful.

/data/oracle/product/10.2/crs/bin/srvctl add nodeapps -n racnode3 -A racnode3-vip/255.255.255.0/ce0 -o /data/oracle/product/10.2/crs
