2013年8月12日，客戶有一套AIX 7.1 + oracle 11.2.0.3 的RAC資料庫，現客戶要求該資料庫只在內網訪問，需要修改public IP、VIP和scan-IP。參考了mos上的兩篇文件，按文件進行了修改，過程如下:

修改前IP                    修改後IP
192.168.156.211          10.3.1.211         db1
192.168.156.212          10.3.1.212         db2
192.168.156.213          10.3.1.213         db1-vip
192.168.156.214          10.3.1.214         db1-vip
172.16.156.211            172.16.156.211   db1-priv   #不需要修改
172.16.156.212            172.16.156.212   db2-priv   #不需要修改
192.168.156.215          10.3.1.215         db-scan

一、停止CRS相關資源的啟動

1、禁止所有節點自啟動及停止節點資料庫、監聽(在一個節點執行)

[[email protected] bin]# ./srvctl disable listener -n db1
[[email protected] bin]# ./srvctl disable listener -n db2
[[email protected] bin]# ./srvctl stop listener -n db1
[[email protected] bin]# ./srvctl stop listener -n db2
[[email protected]
 
 bin]# ./srvctl disable database -d prudb
[[email protected] bin]# ./srvctl stop database -d prudb -o immediate

2、禁止所有節點自啟動並停止vip(必須與/etc/hosts檔案中的vip名稱)(在一個節點執行)

[[email protected] bin]# ./srvctl disable vip -i db1-vip
[[email protected] bin]# ./srvctl disable vip -i db2-vip
[[email protected]
 
 bin]# ./srvctl stop vip -n db1
[[email protected] bin]# ./srvctl stop vip -n db2

3、禁止所有節點自啟動並停止scan_listener(在一個節點執行)

[[email protected] bin]# ./srvctl disable scan_listener
[[email protected] bin]# ./srvctl disable scan
[[email protected] bin]# ./srvctl stop scan_listener
[[email protected] bin]# ./srvctl stop scan

4、停止節點的crs

[[email protected] bin]# ./crsctl stop crs           (所有節點執行)
CRS-2791: Starting shutdown of Oracle High Availability
…… CRS-4133: Oracle High Availability Services has been stopped.

二、修改public IP、VIP、scan_IP

1、修改/etc/hosts檔案

修改public IP、VIP、scan-IP

2、修改網絡卡IP地址

smitty tcpip -> minimum configuration & startup -> en0

3、檢查網絡卡配置是否生效

Ifconfig -a

4、啟動crs(所有節點執行)

[[email protected] bin]# ./crsctl start crs

5、叢集public IP重新設定

• 檢視public IP

[[email protected] bin]# ./oifcfg getif
en1  172.16.156.0        global  cluster_interconnect
en0  192.168.156.0       global  public

• 刪除舊配置

[[email protected] bin]# ./oifcfg delif -global en0/192.168.156.0

• 重新配置

[[email protected] bin]# ./oifcfg setif -global en0/10.3.1.0:public

• 驗證

[[email protected] bin]# ./oifcfg getif
en1  172.16.156.0  global  cluster_interconnect
en0  10.3.1.0  global  public

6、叢集vip重新設定

• 檢視叢集VIP

[[email protected] bin]# ./srvctl config vip -n db1
VIP exists: /db1-vip/192.168.156.213/192.168.156.0/255.255.255.0/en0, hosting node db1
[[email protected] bin]# ./srvctl config vip -n db2
VIP exists: /db2-vip/192.168.156.214/192.168.156.0/255.255.255.0/en0, hosting node db2

• 進行修改

[[email protected] bin]# ./srvctl modify nodeapps -n db1 -A 10.3.1.213/255.255.255.0/en0
[[email protected] bin]# ./srvctl modify nodeapps -n db2 -A 10.3.1.214/255.255.255.0/en0

• 驗證

[[email protected] bin]# ./srvctl config vip -n db1
VIP exists: /db1-vip/10.3.1.213/10.3.1.0/255.255.255.0/en0, hosting node db1
[[email protected] bin]# ./srvctl config vip -n db2
VIP exists: /db2-vip/10.3.1.214/10.3.1.0/255.255.255.0/en0, hosting node db2

7、叢集scan IP重新設定

• 檢視scan IP

[[email protected] bin]# ./srvctl config scan
SCAN name: 192.168.156.215, Network: 1/192.168.156.0/255.255.255.0/en0
SCAN VIP name: scan1, IP: /192.168.156.215/192.168.156.215

• 修改scan IP

[[email protected] bin]# ./srvctl modify scan -n 10.3.1.215

• 驗證

[[email protected] bin]# ./srvctl config scan
SCAN name: 10.3.1.215, Network: 1/10.3.1.0/255.255.255.0/en0
SCAN VIP name: scan1, IP: /10.3.1.215/10.3.1.215

• 更新scan_listener

[[email protected] bin]# ./srvctl modify scan_listener -u

三、啟動並開啟CRS資源的自啟動

1、啟動listener

[[email protected] bin]# ./srvctl enable listener -n db1
[[email protected] bin]# ./srvctl enable listener -n db2
[[email protected] bin]# ./srvctl enable vip -i db1-vip
[[email protected] bin]# ./srvctl enable vip -i db2-vip
[[email protected] bin]# ./srvctl start listener -n db1
[[email protected] bin]# ./srvctl start listener -n db2

2、啟動scan_listener

[[email protected] bin]# ./srvctl enable scan_listener
[[email protected] bin]# ./srvctl enable scan
[[email protected] bin]# ./srvctl start scan_listener

3、啟動資料庫

[[email protected] bin]# ./srvctl enable database -d prudb
[[email protected] bin]# ./srvctl start database -d prudb

4、在節點中修改local_listener引數

alter system set local_listener='(ADDRESS = (PROTOCOL = TCP)(HOST =db1-vip)(PORT = 1521))' scope=both sid='prudb1';
alter system set local_listener='(ADDRESS = (PROTOCOL = TCP)(HOST =db2-vip)(PORT = 1521))' scope=both sid='prudb2';

四、關於RAC環境下，修改hostname

hostname在安裝好了以後就不能修改了。如果要修改，只能通過”刪除節點->新建節點“的方式修改
