Oracle 11g 安装完毕后，如果有卸载的需要。可以有如下方法：
- 手工删除Oracle安装时建立的各目录、文件等。这种方法对于Linux还算可行，但是Window版中涉及到服务、注册表等等。往往删除不干净。
- 使用安装目录$ORACLE_HOME/deinstall/下的 deinstall脚本。

在删除的过程中有以下几点需要确认的
Specify the list of database names that are configured in this Oracle home [orcl]:
指定需要删除的数据库名称，默认即可，直接回车。
The details of database(s) orcl have been discovered automatically. Do you still want to modify the details of orcl database(s)? [n]:
是否需要修改数据库的详细信息，默认n，直接回车。
Do you want to continue (y - yes, n - no)? [n]: y
是否继续，填写y，回车
脚本结尾，提示需要使用root用户删除如下三个脚本。
rm -rf /etc/oraInst.loc rm -rf /opt/ORCLfmap rm -rf /etc/oratab
至此，Oracle删除完毕。
将Oracle软件再次安装
./runInstaller -silent -responseFile /home/oracle/etc/install_software_only.rsp
3. 使用专用工具
Oracle官方推荐使用专门的删除工具。原因是内置的deinstall工具脚本中常常带有很多bug，很多时候不能完全的将其删除干净。特别是Windows环境下的卸载工具，不能正常工作的场景很多。
上传工具包至服务器，直接解压，解压完毕后即可直接使用。
