oracle 11gR2 新增deinstall命令来卸载grid和database

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
下面为第一点的使用方法是交互式的
cd $ORACLE_HOME/deinstall/
p570b@oracle$deinstall
