可以使用deinstall命令停止和删除Oracle数据库主目录中的Oracle数据库软件和组件。
可以使用卸载来删除以下软件:
Oracle数据库
Oracle网格基础架构，包括Oracle集群件和Oracle自动存储管理(Oracle ASM)
Oracle真实应用集群(Oracle RAC)
Oracle数据库客户端
可以在Oracle主目录中使用deinstall命令。它位于$ORACLE_HOME/deinstall目录中。deinstall通过使用Oracle主目录中的信息和用户提供的信息来创建响应文件。用户可以使用之前通过使用-checkonly选项运行deinstall命令生成的响应文件。用户还可以编辑响应文件模板。
如果运行deinstall来删除Oracle Grid Infrastructure安装，则卸载程序会提示用户以root用户身份运行deinstall命令。对于集群的Oracle网格基础设施，脚本是rootcrs.sh，对于独立服务器的Oracle网格基础设施(Oracle Restart)，脚本是roothas.sh。
