Oracle 学习之卸载Oracle 11g

Oracle 11g 安装完毕后，如果有卸载的需要。可以有如下方法：

1. 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。

2. 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.locrm -rf /opt/ORCLfmaprm -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。

[oracle@localhost ~]$ unzip p13390677_112040_Linux-x86-64_7of7.zip
