这篇文章给大家分享的是有关如何卸载grid软件的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

在安装grid的时候，由于某种原因需要将grid软件卸载重新装，在网上搜集到如下信息：

在Oracle 11gR2以前的版本中,卸载CRS和oracle database时需要手工去删除部分东西，从oracle 11gR2版本开始新增deinstall命令可以卸载grid和database，new oui版本中不再支持卸载,可以删除的非常干净,需要手工删除的话,deinstall命令也会有提示出来。

有两种方法可以删除oracle home和grid home

1、使用安装好后的$ORACLE_HOME/deinstall/deinstall命令

2、从oracle官方网站上下载的deinstall工具 介质名称为aix.ppc64_11gR2_deinstall.zip

直接执行第一种方法，进入到$ORACLE_HOME/deinstall/下，执行deinstall

cd $ORACLE_HOME/deinstall/

./deinstall
