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版本号上，能够在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，而且能够同一时候为多个主机安装agent代理。

官方文档：

或是

sudoers文件默认是仅仅读的

[root@racdb1app]# chmod 777 /etc/sudoers

[root@racdb1app]# vi /etc/sudoers

或是：

假设通过上面的两个设置无论用。或是忽略使用sudo运行root脚本

 

部署完毕后。在目标端用root用户登录，运行

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文件夹内容

[oracle@singleagent]$ ls

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

[oracle@singleagent]$ rm -rf *
