如何在oracle集群中更換私有網絡的網卡

編輯:Oracle教程

   如何在oracle 集群中更換私有網絡的網卡。

  今天是2014-03-17,目前學習進度也正在緊鑼密鼓的進行著,今天把一小部分實驗在做一下記錄一下筆記。

  我們知道RAC網絡有私有網絡和公用網絡,公用網絡提供客戶訪問請求,私用網絡提供oracle 的cache fusion和節點心跳等作用,因為在11G R2可以執行4個private network 進行cache fusion。

  但在剛剛開始安裝的時候進行了忽略,那麼安裝之後如何修改呢?且該環節可以模擬oracle RAC怎麼添加私用網卡,如果替換損壞網卡等真實環節。

  另外對於網絡調整無非有、更改私用主機名啊、不改變網段和掩碼改變私用地址啊、改變私有網絡的mtu啊、改變私有網卡子網或是掩碼,這麼幾種情況。

  今天就談如何改變私網網卡。那麼這時候需要使用一個工具叫oracle interface configuration assistant(oifcfg).

  在11G r2之前,oracle在ocr中存儲網絡接口名稱和子網信息,那麼使用oifcfg即可完成修改:

  1、增加和刪除私網接口

  增加一個私網接口

  $ORA_CRS_HOME/bin/oifcfg setif -global /:cluster_interconnect

  刪除一個私網接口

  $ORA_CRS_HOME/bin/oifcfg delif -global /

  2、查看網卡改變情況

  $ORA_CRS_HOME/bin/oifcfg getif

  3、重啟集群

  crsctl stop crs

  crsctl start crs

  那麼對於oracle 11G R2或是更高版本,如何修改私網呢?

  在11.2gi中,私有網絡配置不在保存在ocr中,而是保存在gpnp profile文件中,該文件是一個xml文件,不推薦使用手動編輯,在進行配置私網之前

  首先需要備份該文件,進而進行後續操作。由於我的實驗環境正好是11.2.0.4,因此隨即記錄真實修改過程。

  1、備份gpnp profile 文件(每個節點都要備份)。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 [root@rac-two ~]# su - grid [grid@rac-two ~]$ cd /u01/app/11.2.0/grid/gpnp/rac-two/profiles/peer/ [grid@rac-two peer]$ ls -l total 12 -rw-r--r-- 1 grid oinstall 1857 Feb 25 21:54 profile.old -rw-r--r-- 1 grid oinstall 1830 Feb 13 02:27 profile_orig.xml -rw-r--r-- 1 grid oinstall 1896 Feb 25 21:58 profile.xml [grid@rac-two peer]$ cp profile.xml profile.xml_bak [grid@rac-two peer]$ ls -ltr total 16 -rw-r--r-- 1 grid oinstall 1830 Feb 13 02:27 profile_orig.xml -rw-r--r-- 1 grid oinstall 1857 Feb 25 21:54 profile.old -rw-r--r-- 1 grid oinstall 1896 Feb 25 21:58 profile.xml -rw-r--r-- 1 grid oinstall 1896 Mar 17 17:48 profile.xml_bak [grid@rac-two peer]$

  2、查看目前節點私網信息

  節點二:

?

1 2 3 4 5 6 7 8 9 10 [grid@rac-two peer]$ oifcfg getif eth0  192.168.4.0  global  public eth3  192.168.2.0  global  cluster_interconnect [grid@rac-two peer]$ oifcfg iflist -p -n eth0  192.168.4.0  PRIVATE  255.255.255.0 eth3  192.168.2.0  PRIVATE  255.255.255.0 eth3  169.254.0.0  UNKNOWN  255.255.0.0 eth1  192.168.1.0  PRIVATE  255.255.255.0 eth2  192.168.1.0  PRIVATE  255.255.255.0 [grid@rac-two peer]$

  節點一:

?

1 2 3 4 5 6 7 8 9 10 [grid@rac-one peer]$ oifcfg getif eth0  192.168.4.0  global  public eth3  192.168.2.0  global  cluster_interconnect [grid@rac-one peer]$ oifcfg iflist -p -n eth0  192.168.4.0  PRIVATE  255.255.255.0 eth1  192.168.1.0  PRIVATE  255.255.255.0 eth2  192.168.1.0  PRIVATE  255.255.255.0 eth3  192.168.2.0  PRIVATE  255.255.255.0 eth3  169.254.0.0  UNKNOWN  255.255.0.0 [grid@rac-one peer]$

  目前可以知道集群內部連接私有網絡設備名為eth3,所需要做的是將集群內部私有網絡設備名由eth3改變為eth1和eth2.

  3、增加新的集群內部連接

?

1 2 3 [grid@rac-one peer]$ oifcfg setif -global eth1/192.168.1.0:cluster_interconnect [grid@rac-one peer]$ oifcfg setif -global eth2/192.168.1.0:cluster_interconnect [grid@rac-one peer]$

  4、驗證

  節點一:

?

1 2 3 4 5 6 [grid@rac-one peer]$ oifcfg getif eth0  192.168.4.0  global  public eth3  192.168.2.0  global  cluster_interconnect eth1  192.168.1.0  global  cluster_interconnect eth2  192.168.1.0  global  cluster_interconnect [grid@rac-one peer]$

  節點二:

?

1 2 3 4 5 6 [grid@rac-two peer]$ oifcfg getif eth0  192.168.4.0  global  public eth3  192.168.2.0  global  cluster_interconnect eth1  192.168.1.0  global  cluster_interconnect eth2  192.168.1.0  global  cluster_interconnect [grid@rac-two peer]$

  5、刪除192.168.2.0這個集群內部連接:

  [grid@rac-two peer]$ oifcfg delif -global eth3/192.168.2.0

  [grid@rac-two peer]$

  6、在所有節點關閉集群和禁用crs服務且重啟
