Oracle 11g Grid Infrastructure 卸载

Oracle 11g Grid Infrastructure 卸载

Oracle 11g grid infrastructure安装失败时，或者需要卸载时，不像10g的CRS组件卸载那么麻烦了。

以linux系统为例，10g手工删除CRS的操作步骤：

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，提供了一个卸载工具deinstall，，如Linux系统下软件名称为linux.x64_11gR2_deinstall.zip。解压后可以直接使用。

第一步、使用grid用户登录操作系统，这个用户是grid infrastructure软件安装用户。

############ ORACLE DEINSTALL & DECONFIG TOOL START ############

Usage:

deinstall -home
[ -silent ]
[ -checkonly ]
[ -local ]
[ -paramfile ]
[ -params ]
[ -o ]
[ -help | -h: Type -h or -help to get more information on each o
f the above options. ]
Specify any of the above options.

############# ORACLE DEINSTALL & DECONFIG TOOL END #############

第二步，使用deinstall -home /u01/app/11.2.0/grid 卸载安装了的文件

/home/grid/deinstall@serv2=>+ASM2$./deinstall -home /u01/app/11.2.0/grid
ORACLE_HOME = /u01/app/11.2.0/grid

—————————————->

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

这个步骤中就是为了生成配置文件/home/grid/deinstall/response/deinstall_Ora11g_gridinfrahome1.rsp

第三步，使用root在节点上执行上一个步骤中生成的配置文件的perl脚本

/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，卸载grid infrastructure工作结束。在/etc/init.d中也不会有ohasd相关的文件了。
