重新配置db control和agent的端口
emctl start console

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$ORACLE_HOME/install/portlist.ini
文件可以知道当前dbcontrol正在使用的端口,
默认dbcontrol http端口1158,agent端口3938。
如果要重新配置端口,可以使用如下命令:
emca -reconfig ports -dbcontrol_http_port 1159
emca -reconfig ports -agent_port 3939
端口在$ORACLE_HOME\install下面的portlist.ini文件中查到
也可以到这个目录下的emca.properties文件中查看em端口:/.../sysman/config/emca.properties。其中 /.../为你的Oracle安装路径,我的为/oracle/oracle10g/sysman/config。
Oracle10G的EM采用了web方式,并且分成了2个产品,database control和grid control。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。
