linux下配置oracle 10G EM Database Console
1、启动dbconsole
[oracle@devrfel501 ~]$ emctl start dbconsole
如果提示：OC4J Configuration issue. /opt/oracle/product/10.2.0/oc4j/j2ee/OC4J_DBConsol，则说明没有配置或没有创建
2、配置dbconsole
[oracle@devrfel501 ~]$ emca -config dbcontrol db

3、查看dbconsole的状态和访问地址
[oracle@devrfel501 ~]$ emctl status dbconsole
TZ set to PRC
Oracle Enterprise Manager 10g Database Control Release 10.2.0.4.0
Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
https://devrfel501:5502/em/console/aboutApplication #访问地址

4、删除数据库的 Database Control配置
oracle@devrfel501 ~]$ emca -deconfig dbcontrol db
5、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。
