GC agent的安装和卸载

一、GC agent安装

下面介绍GC agent的push和pull两种安装方法

1、push（推送）安装GC agent方法

　　1）、打开EMGC home page：https://even.oracle.com:7799/em/

　　登录EMGC 密码/账号：sysman/oracle12

　　Click "Deployments" - >
　　-> Click Agent Installation "Install Agent" - >
　　-> Click "Fresh Install" - >
　　-> Source Shiphome Directory = "Default, from Management Server location."->
　　-> Version = "11.1.0.1.0" - > "
　　-> Platform = "Linux x86" - >"
　　-> Provide Host List = "odd.oracle.com" - >
　　-> Username = oracle - >
　　-> Password = **** ->
　　-> Deselect "Run root.sh" (待完成后手工执行) ->
　　-> Installation Base Directory = "/u01/app/oracle/middleware" -> 注： 安装时将自动建立此目录
　　-> Port = 3872 - >
　　-> Management Server Registration Password = **** -> (本例： oracle12)
　　-> Confirm Password = **** ->
　　-> Click "Continue" - >
　　-> Deselect "I wish to receive security updates via My Oracle Support."->
　　-> Click "Submit" - >
　　-> Click "Yes" ->
　　-> wait for installation completed -> Click "Done" 

　　2）、root用户执行以下脚本

　　/u01/app/oracle/middleware/agent11g/root.sh

　　3）、agent安装完成之后，可以查看各个target的状态。

　　可以看到DB PROD1和PROD2的status显示为未知，这里需要我们手工配置。

 

2、pull（拉）安装GC agent

 $wget --no-check-certificate https://even.oracle.com:7799/agent_download/11.1.0.1.0/linux/agentDownload.linux

给agentDownload.linux文件添加执行权限

chmod 775 agentDownload.linux

安装GC agent，-b指定安装目录，-y表示默认为yes，密码为安装EMGC时设置的密码。

./agentDownload.linux -b /u01/app/oracle/middleware -y

agent安装完成后，查看agent状态

[oracle@odd- stage]$ emctl status agent

root用户执行脚本：/u01/app/oracle/middleware/agent11g/root.sh 

agent安装文成。

二、GC agent卸载

1、停止运行GC agent

[oracle@odd- bin]$ emctl stop agent
Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0
Copyright (c) 1996, 2010 Oracle Corporation. All rights reserved.
Stopping agent ... stopped.

[oracle@odd- bin]$ emctl status agent
Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0
Copyright (c) 1996, 2010 Oracle Corporation. All rights reserved.
---------------------------------------------------------------
Agent is Not Running

2、在EMGC删掉所有关于client host的target

EMGC home page ---> targets ---> all targets

按以下 Target Type 次序（不按次序将有错误提示）， 逐个 remove client 相关的全部 target。
 Listener
 Database Instance
 +ASM, High Availability Service(HAS)
 Host
 Agent

 

以上为listener target的删除示范，按照这个方法将其余关于client host的target全部删掉。

3、运行卸载程序

target全部删掉之后即可运行GC agent的卸载程序

 $ /u01/app/oracle/middleware/agent11g/oui/bin/runInstaller

4、删除GC agent环境

#vi /etc/oratab

*:/u01/app/oracle/middleware/agent11g:N
PROD2:/u01/app/oracle/product/11.2.0/dbhome_1:N # line added by Agent
PROD1:/u01/app/oracle/product/11.2.0/dbhome_1:N # line added by Agent

将红色字体的agent相关信息删去。

5、删除agent的安装目录

rm -rf $AGENT_HOME

至此agent删除完成。
