2.停掉Agent
[oracle@secdb1 bin]$ ./emctl stop agent
Oracle Enterprise Manager 10g Release 10.2.0.1.0.
Copyright (c) 1996, 2005 Oracle Corporation. All rights reserved.
Stopping agent ... stopped.

3.删除Agent对应的软件
此处使用静默方式完成Agent软件删除。
[oracle@secdb1 bin]$ cd /u01/app/oracle/agent/agent10g/oui/bin
[oracle@secdb1 bin]$ pwd
/u01/app/oracle/agent/agent10g/oui/bin
[oracle@secdb1 bin]$ ./runInstaller -silent -deinstall -removeallfiles -removeAllPatches REMOVE_HOMES="{/u01/app/oracle/agent/agent10g}"

4.删除inventory.xml文件中有关Agent的信息
inventory.xml文件存放在oraInventory目录下的ContentsXML目录中。
1）确认oraInventory文件夹存放位置的方法
/etc/oraInst.loc文件中记录了oraInventory文件夹的位置
[oracle@secdb1 agent]$ cat /etc/oraInst.loc
inventory_loc=/u01/app/oracle/oraInventory
inst_group=oinstall

2）删除inventory.xml文件中<HOME_LIST>中NAME是agent10g的内容
[oracle@secdb1 ~]$ vi /u01/app/oracle/oraInventory/ContentsXML/inventory.xml
<?xml version="1.0" standalone="yes" ?>


<INVENTORY>
<VERSION_INFO>
   <SAVED_WITH>10.2.0.5.0</SAVED_WITH>
   <MINIMUM_VER>2.1.0.6.0</MINIMUM_VER>
</VERSION_INFO>
<HOME_LIST>
<HOME NAME="OraDb10g_home1" LOC="/u01/app/oracle/product/10.2.0/db_1" TYPE="O" IDX="1"/>
<HOME NAME="agent10g" LOC="/u01/app/oracle/agent/agent10g" TYPE="O" IDX="2" REMOVED="T"/>
</HOME_LIST>
</INVENTORY>

5.删除agent目录
[oracle@secdb1 oracle]$ rm -rf $ORACLE_BASE/agent?

6.小结
按照上述步骤便可以顺利地删除Grid Control Agent软件，以便重新部署安装Agent。
重点关注上述步骤中的第4步骤，这个步骤是容易遗忘的地方，切记。

Good luck.
