1. 概述
Oracle EM11g的资料库需要进行迁移，它的主要操作步骤如下：
1、关闭OMS
2、全库备份现在的资料库，再恢复到新服务器上
3、更新OracleEM OMS的连接资料库的配置
4、启动OMS
这个操作方法在Oracle EM 12c中也有效。
2. 操作步骤
第一步，关闭OMS
找到OMS所在的bin下的emctl工具，关闭OMS服务
/u01/app/oracle/middlehome/oms11g/bin@lin-65-210-dba=>emgrid$./emctlstop oms

第二步，使用RMAN备份恢复一下，很简单，不解释。
第三步，更新Oracle EM OMS的连接资料库的配置
首先检查一下资料库连接配置详情。
/u01/app/oracle/middlehome/oms11g/bin@lin-65-210-dba=>emgrid$./emctlconfig oms -list_repos_details
Oracle Enterprise Manager 11g Release 1 Grid Control

Repository Connect Descriptor :(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.65.14)(PORT=6688)))(CONNECT_DATA=(SID=emrep)))
Repository Host :
Repository SID :
Repository User : SYSMAN
通过emctl工具修改EM GRID CONTROL的资料库配置,emctl提供了两个修改方法。
emctl config oms -store_repos_details (-repos_host -repos_port -repos_sid | -repos_conndesc ) -repos_user [-repos_pwd ][-no_check_db]
Connect descriptor should be enclosed in quotes. eg:'""' or "''"
具体执行的命令如下：
emctl config oms -store_repos_details -repos_conndesc"'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.65.8)(PORT=6688)))(CONNECT_DATA=(SID=emrep)))'"-repos_user sysman -repos_pwd welcome2012
emctl config oms -store_repos_details -repos_host 192.168.65.8-repos_port 6688 -repos_sid emrep -repos_user SYSMAN -repos_pwd welcome2012
最后，修改这两个命令中的一个。
/u01/app/oracle/middlehome/oms11g/bin@lin-65-210-dba=>emgrid$emctlconfig oms -store_repos_details -repos_conndesc"'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.65.8)(PORT=6688)))(CONNECT_DATA=(SID=emrep)))'"-repos_user sysman -repos_pwd welcome2012

第四步，启动OMS
