Oracle 11g解除安裝

Oracle 11g解除安裝

---

Oracle 11g grid infrastructure安裝失敗時，或者需要解除安裝時，不像10g的CRS元件解除安裝那麼麻煩了。
以linux系統為例，10g手工刪除CRS的操作步驟：
 
rm -f /etc/init.d/init.cssd
rm -f /etc/init.d/init.crs
rm -f /etc/init.d/init.crsd
rm -f /etc/init.d/init.evmd
rm -f /etc/rc2.d/K96init.crs
rm -f /etc/rc2.d/S96init.crs
rm -f /etc/rc3.d/K96init.crs
rm -f /etc/rc3.d/S96init.crs
rm -f /etc/rc5.d/K96init.crs
rm -f /etc/rc5.d/S96init.crs
rm -rf /etc/oracle/scls_scr
rm -f /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

 
在11g中，提供了一個解除安裝工具deinstall，如Linux系統下軟體名稱為linux.x64_11gR2_deinstall.zip。解壓後可以直接使用。

第一步、使用grid使用者登入作業系統，這個使用者是grid infrastructure軟體安裝使用者。

[grid@exadata tmp]$ unzip linux.x64_11203_deinstall.zip
[grid@exadata tmp]$ cd deinstall/
[grid@exadata deinstall]$ ll

第二步，使用deinstall -home /u01/app/11.2.0/grid 解除安裝安裝了的檔案
[grid@exadata deinstall]$./deinstall -home /u01/app/11.2.0/grid
ORACLE_HOME = /u01/app/11.2.0/grid

----------------------------------------&gt

Run the following command as the root user or the administrator on node "serv2".


/home/grid/deinstall/perl/bin/perl -I/home/grid/deinstall/perl/lib -I/home/grid/
deinstall/crs/install /home/grid/deinstall/crs/install/rootcrs.pl -force  -delet
e -paramfile /home/grid/deinstall/response/deinstall_Ora11g_gridinfrahome1.rsp -
lastnode

Press Enter after you finish running the above commands
 
這個步驟中就是為了生成配置檔案/home/grid/deinstall/response/deinstall_Ora11g_gridinfrahome1.rsp
 
第三步，使用root在節點上執行上一個步驟中生成的配置檔案的perl指令碼
 
/home/grid/deinstall/perl/bin/perl -I/home/grid/deinstall/perl/lib -I/home/grid/
deinstall/crs/install /home/grid/deinstall/crs/install/rootcrs.pl -force  -delet
e -paramfile /home/grid/deinstall/response/deinstall_Ora11g_gridinfrahome1.rsp -
lastnode
 
至此，解除安裝grid infrastructure工作結束。在/etc/init.d中也不會有ohasd相關的檔案了。
