重新配置與解除安裝11gR2 Grid Infrastructure

Oracle 11g R2 Grid Infrastructure 的安裝與配置較之前的版本提供了更多的靈活性。在Grid Infrastructure安裝完畢前執行root.sh經常容易出現錯誤，並且需要修復該錯誤才能得以繼續。

 

在這個版本中我們可以直接透過執行指令碼rootcrs.pl來重新配置Grid Infrastructure而無需先解除安裝Grid Infrastructure，然後修復故障後進行再次安裝。下面描述了rootcrs.pl的用法以及使用deinstall徹底解除安裝Grid Infrastructure。

#命令位置:$GRID_HOME/crs/install  

#命令說明:  

#  該命令主要是用於對crs進行維護與管理，包括patch,upgrade,downgrade,deconfig等等  

#  perldoc rootcrs.pl執行這個命令獲得完整的介紹  

[root@linux1 install]# ./rootcrs.pl -h  

Unknown option: h  

Usage:  

      rootcrs.pl [-verbose] [-upgrade | -patch] [-hahome ]  

                 [-paramfile ]   

                 [-deconfig | -downgrade] [-force] [-lastnode]  

                 [-downgrade] [-oldcrshome ] [-version ]    

                 [-unlock [-crshome ]]  

   

      Options:  

       -verbose    Run this script in verbose mode  

       -upgrade    Oracle HA is being upgraded from previous version  

       -patch      Oracle HA is being upgraded to a patch version  

       -hahome     Complete path of Oracle Clusterware home  

       -paramfile  Complete path of file specifying HA parameter values 

       -lastnode   Force the node this is executing on to be considered the  

                   last node of the install and perform actions associated  

                   with configurig the last node  

       -downgrade  Downgrade the clusterware  

       -version    For use with downgrade; special handling is required if  

                   downgrading to 9i. This is the old crs version in the format  

                   A.B.C.D.E (e.g 11.1.0.6.0).  

       -deconfig   Remove Oracle Clusterware to allow it to be uninstalled or reinstalled.  

       -force      Force the executon of steps in delete that cannot be verified   

                   to be safe  

       -unlock     Unlock CRS home   

       -crshome    Complete path of crs home. Use with unlock option.  

       -oldcrshome For use with downgrade. Complete path of the old crs home.  

   

      If neither -upgrade nor -patch is supplied, a new install is performed  

   

      To see the full manpage for this program, execute:  

        perldoc rootcrs.pl       

#對於執行root.sh失敗時，我們可以透過該命令以-deconfig 引數來清除crs的配置資訊，然後根據log修復故障或使用patch之後再重新執行root.sh

#對於該命令的patch,upgrade,downgrade用法再此不作詳細介紹

 

 

2、重新配置Grid Infrastructure及ASM

[python] 

#重新配置Grid Infrastructure並不會移除已經複製的二進位制檔案，僅僅是回覆到配置crs之前的狀態，下面是其步驟  

   

a、使用root使用者登入，並執行下面的命令(所有節點，但最後一個節點除外)  

  # perl $GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force 

     

b、同樣使用root使用者在最後一個節點執行下面的命令。該命令將清空ocr 配置和voting disk    

  # perl $GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode  

   

c、如果使用了ASM磁碟，繼續下面的操作以使得ASM重新作為候選磁碟(清空所有的ASM磁碟組)  

  # dd if=/dev/zero of=/dev/sdb1 bs=1024 count=100  

  # /etc/init.d/oracleasm deletedisk DATA /dev/sdb1  

  # /etc/init.d/oracleasm createdisk DATA /dev/sdb1
