网格控制器的客户端agent安装方式主要有OUI,COLNE,PUSH,PULL等几种,11g的版本的网格控制器agent不支持OUI方式安装,因而想要使用11g版本的OMA,需要采用后面三种方式安装!这三种方式当中,最快的应该是COLNE方式,其次是PULL方式,PUSH方式安装经过测试发现比较占用OMS服务器资源!本文介绍些如何在rhel5.4上使用PULL方式安装客户端agent,这种安装方法也叫做agentdownload方式!
PUSH方式安装请参考:http://ylw6006.blog.51cto.com/470441/775477

一:确定OMS正常运行,将agentdownload脚本发送到客户端上
- [oracle@ora11g ~]$ $OMS_HOME/bin/emctl status oms
- Oracle Enterprise Manager 11g Release 1 Grid Control
- Copyright (c) 1996, 2010 Oracle Corporation. All rights reserved.
- WebTier is Up
- Oracle Management Server is Up
- [oracle@ora11g ~]$ $AGENT_HOME/bin/emctl status agent

二:在本例中客户端只安装数据库软件,未建库;在客户端上运行脚本进行安装
- [oracle@server49 ~]$ env |grep ORA
- ORACLE_SID=orcl
- ORACLE_BASE=/u01/app/oracle
- ORACLE_HOME=/u01/app/oracle/product/10.2.0/db1
- [oracle@server49 ~]$ ps -ef |grep ora

- [oracle@server49 ~]$ sh agentDownload.linux_x64 -b /u01/app/oracle -m ora11g.yang.com -r 4900 -y

- Provide the Agent Registration password so that the Management Agent can communicate with Secure Management Service.
- Note: You may proceed with the installation without supplying the password; however, Management Agent can be secured manually after the installation.
- If Oracle Management Service is not secured, agent will not be secured, so continue by pressing Enter Key.
- Enter Agent Registration Password: (此处输入密码)

三:验证安装后,在客户端上建库测试
- [oracle@server49 ~]$ /u01/app/oracle/agent11g/bin/emctl status agent

四:排错示例
1:在另外一台服务器上同样的方式安装完agent后,发现启动agent报错如下
- [oracle@dg1 ~]$ /u01/app/oracle/agent11g/bin/emctl secure agent
- Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0

- Agent is Not Running
- [oracle@dg1 ~]$ /u01/app/oracle/agent11g/bin/emctl start agent

- Starting agent ……. failed.
- Failed to initialize the Fetchlet Manager.
- Consult the log files in: /u01/app/oracle/agent11g/sysman/log
2:查看日志后,猜想是由于该数据库服务器上存在EM的问题,因而删除EM,删除后,发现错误依旧!
- [oracle@dg1 log]$ pwd
- /u01/app/oracle/agent11g/sysman/log
- [oracle@dg1 log]$ tail -2 emagent.trc

3:发现该服务器的主机名解析只是单纯使用DNS,未使用hosts文件
- [root@dg1 ~]# hostname
- dg1.yang.com
- [root@dg1 ~]# cat /etc/hosts
- # Do not remove the following line, or various programs
- # that require network functionality will fail.
- 127.0.0.1 localhost.localdomain localhost
- ::1 localhost6.localdomain6 localhost6
- 192.168.1.61 dg1.yang.com dg1 #(添加这行)
- 设置下ORACLE_UNQNAME变量,启动agent,居然奇迹般的正常了!
- [oracle@dg1 log]$ export ORACLE_UNQNAME=dg1.yang.com
- [oracle@dg1 log]$ /u01/app/oracle/agent11g/bin/emctl start agent

结论:在使用网格控制器agent的服务器上,本机主机名的解析在hosts文件中必须指定;同一台服务器,可以同时使用EM和GC管理数据库
