Oracle10G的EM采用了web方式，并且分成了2个产品，database control和grid control。这里主要介绍如何创建单数据的dbcontrol。Grid control需要下载单独的光盘安装。
在用DBCA建库的时候，可以选择是否启用dbcontrol，启用的话需要在数据库中建立一个sysman的schema，用于保存EM的一些数据，这个就是EM的资料库(repository)。
使用命令行工具emca可以创建，修改，重建或者删除dbcontrol的配置。

SQL> select * from v$version;

TNS for Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production

由于要在数据库中建EM资料库，数据库和监听都必须已经启动并正常工作。
配置dbcontrol
[oracle@oracle10 ~]$ emca -config dbcontrol db

此时运行emctl命令的显示是：
[oracle@oracle10 ~]$ emctl status dbconsole
TZ set to PRC
OC4J Configuration issue. /opt/oracle/product/10.2.0/Database/oc4j/j2ee/OC4J_DBConsole_oracle10_orcl not found.

常用的命令语法：
emca -repos create创建一个EM资料库
emca -repos recreate重建一个EM资料库
emca -repos drop删除一个EM资料库
emca -config dbcontrol db配置数据库的 Database Control
emca -deconfig dbcontrol db删除数据库的 Database Control配置
emca -reconfig ports 重新配置db control和agent的端口
emctl start console启动EM console服务，使用前需要先设置ORACLE_SID环境变量
emctl stop console停止EM console服务，使用前需要先设置ORACLE_SID环境变量
注：通过查看$ORACLE_HOME/install/portlist.ini 文件可以知道当前dbcontrol正在使用的端口，默认dbcontrol http端口1158，agent端口3938。如果要重新配置端口，可以使用如下命令：
emca -reconfig ports -dbcontrol_http_port 1159
emca -reconfig ports -agent_port 3939
使用命令行工具emctl可以启动/停止console服务，察看服务状态等。
