安装oracle软件（略）
解压模板文件12.1.0.2.0_Database_Template_for_EM12_1_0_5_0_Linux_x64.zip到
unzip -d $ORACLE_HOME/assistants/dbca/templates 12.1.0.2.0_Database_Template_for_EM12_1_0_5_0_Linux_x64.zip
然后使用该模板安装数据库实例
如果数据库配置了dbcontrol，使用如下命令将其删除：
$ emca -deconfig dbcontrol db -repos drop-SYS_PWD -SYSMAN_PWD
sqlplus / AS SYSDBA
execDBMS_AUTO_TASK_ADMIN.DISABLE(client_name => 'auto optimizer statscollection',operation => NULL,window_name => NULL);

--验证先决条件
install/requisites/bin/emprereqkit
However, if you plan to use a databaseinstance that was created with a preconfigured Management Repository using thedatabase templates offered by Oracle, then make sure you pass the followingparameter while invoking the EM Prerequisite Kit.
-componentVariablesrepository:EXECUTE_CHECKS_NOSEED_DB_ FOUND:false
If you accidently exit the installer beforeclicking Retry, then do NOT restart the installer to reach the same screen;instead, invoke the runConfig.sh script from the OMS home to rerun the ConfigurationAssistant in silent mode. For Microsoft Windows platforms, invoke runConfig.batscript.
$<OMS_HOME>/oui/bin/runConfig.shORACLE_HOME= MODE=perform ACTION=configureCOMPONENT_XML={encap_oms.1_0_0_0_0.xml}
If you have run the installation wizard andlet the installation wizard take corrective actions to correct the repositorysettings, and if you have exited the wizard without completing the installationprocess, then remember that the repository settings might not reset to theiroriginal values because you abruptly ended the installation. In this case,before invoking the installation wizard again, run the following command tomanually reset the values
/install/requisites/bin/emprereqkit-executionType install -prerequisiteXMLRootDir -connectString -dbUser SYS-dbPassword -reposUser sysman -dbRole sysdba -runPrerequisites-runPostCorrectiveActions
./runInstaller -pluginLocation <absolute_path_to_plugin_software_location>
----修改是否自动启动 true:自动启动
./runInstaller START_OMS=trueb_startAgent=false
$<OMS_HOME>/bin/emctl status oms
$<AGENT_HOME>/bin/emctl status agent
$<AGENT_HOME>/bin/emctl upload agent
安装完默认情况下只启用HTTPS,开启HTTP
emctl secure unlock -console
检查plugins是否安装成功（WARN:Plugin configuration has failed）
$<AGENT_HOME>/cfgtoollogs/cfgfw/CfmLogger-<timestamp>.log
修改内部用户密码，如SYSMAN_MDS, SYSMAN_OPSS, SYSMAN_APM，先关闭OMS,然后
<OMS_HOME>/bin/emctl config oms-change_repos_pwd
---备份OMS，包括加密key
<OMS_HOME>/bin/emctl exportconfig oms-dir <path_to_backup_location>
安装很费时
安装完成后，可查看
/u01/app/oracle/Middleware/oms/install/具体的安装信息
如：setupinfo.txt可查看oem的地址，comsole的地址
portlist.ini 可查看具体端口
安装em agent
