安装Agent代理

在EM11g时，agent安装是通过在被监制主机端下载agent代理并安装，在EM12c版本上，可以在EM12c服务端，通过“推送”的方式把agent代理在远程安装到被监控的主机端，并且可以同时为多个主机安装agent代理。

官方文档：

安装方法：

首先登录EM12c

选择： 设置 -> 添加目标 -> 手动添加目标

点击：添加手动目标 –> 添加主机

添加主机目标名称和平台

#mkdir /u01/app/agent12c

#chown oracle:oinstall /u01/app/agent12c

#chmod g+w agent12c

点创建身份证明

下一步

点击“部署代理”

如果通过上面的两个设置不管用，或是忽略使用sudo执行root脚本

部署完成后，在目标端用root用户登录，执行

卸载Agent代理

http://docs.oracle.com/cd/E24628_01/install.121/e24089/deinstall_agent.htm#CBBCADCD

[oracle@singlebin]$ pwd

/u01/app/agent12c/core/12.1.0.4.0/oui/bin

[oracle@singlebin]$ ./runInstaller -deinstall ORACLE_HOME=/u01/app/agent12c/agent_inst/core/12.1.0.4.0/-removeallfiles

先选择删除OraHOME1- OraHOME6

再删除sbin12c1

最后删除agent12c1

最后删除agent目录内容

[oracle@singleagent]$ ls

agentimage.properties  agent_inst core  plugins  plugins.txt plugins.txt.status

[oracle@singleagent]$ rm -rf *
