一、dbca删除所有的数据库
说明：
1、$ORACLE_BASE/cfgtoollogs/dbca/DB_NAME中有相关的操作日志
2、主要包含数据库相关的文件，例如tnsnames.ora、TRACE、init.ora等配置
3、如果能够重新定义$ORACLE_BASE/HOME,并且diskgroup可以删除，那么也可以采取rm -rf $ORACLE_HOME、dd 的方法
二、删除ORACLE database software
su - oracle
$cd $ORACLE_HOME/deinstall
./deinstall
说明：
1、deinstall卸载包含数据库，直接删除$ORACLE_HOME,由于$ORACLE_BASE为$ORACLE_HOME上级目录，没有删除（admin/cfgtoollogs/diag等目录被清除。deinstall输出如下：
Detach Oracle home '/u01/app/oracle/product/11.2.0/db_1' from the central inventory on the local node : Done
Delete directory '/u01/app/oracle/product/11.2.0/db_1' on the local node : Done
The Oracle Base directory '/u01/app/oracle' will not be removed on local node. The directory is not empty.
Detach Oracle home '/u01/app/oracle/product/11.2.0/db_1' from the central inventory on the remote nodes 'xxfwb2' : Done
Delete directory '/u01/app/oracle/product/11.2.0/db_1' on the remote nodes 'xxfwb2' : Done
The Oracle Base directory '/u01/app/oracle' will not be removed on node 'xxfwb2'. The directory is not empty.
3、本例子中GI与DATABASE公用目录/u01/app，可考虑不删除下级目录oracle
rm -rf $ORACLE_BASE
cd $ORACLE_BASE
rm -rf admin cfgtoollogs diag
三、删除grid infrastructure
1、使用该版本自带的工具
1）使用grid用户进入执行以下命令：
su - grid
[grid@xxfwb1 ~]$ crsctl stat res -t
