卸载是个很简单的事，如果卸载的不干净也是一件很蛋疼的事，oracle agent卸载分为两大块agent端和oms端
相关脚本信息来自em 官方文档
agent端处理:
1、暴力方式，屡试不爽
1).停止agent，直接删除agent目录，删除oraInventory/ContentsXML目录下inventory.xml 相关13c条目
2).删除/etc/init.d下的gcstartup自动启动脚本
2、官方文档方式：
1).$
For example,
/shared/app/agentbasedir/agent_13.1.0.0.0/perl/bin/perl /shared/app/agentbasedir/agent_13.1.0.0.0/sysman/install/NFSAgentDeInstall.pl AGENT_INSTANCE_HOME=/shared/app/agentbasedir/agent_inst ORACLE_HOME=/shared/app/agentbasedir/agent_13.1.0.0.0
2).删除/etc/init.d下的gcstartup自动启动脚本
oms端处理:
在em control console 里deinstall上面被删除的agent。不然，你会在console界面一直看到被删除的host等信息还在上面
