Oracle 前端之家
前端之家收集整理的这篇文章主要介绍了oracle11g database control，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。


Oracle Enterprise Manager与Oracle Database Control

OEM是一个统称，是Oracle提供的图形化企业级管理工具的统称。具体有三种可用的工具：

（1）Database Control

它用于管理一个数据库（可以是RAC集群数据库），具有实时管理和监视的功能，运行调度作业功能，告警功能。

（2）Application Server Control

用于管理一个或者多个应用服务器实例。

（3）Grid Control

Grid Control可以管理多个数据库和应用服务器，还可以管理计算机节点，支持通过第三方插件管理第三方产品。


Database Control 在oracle10g便加入数据库，安装实例时，提示管理选项。

1、首次尝试查看状态，未配置 EMCA。

oracle@sy-sp1:~>emctlstatusdbconsole
EnvironmentvariableORACLE_UNQNAMEnotdefined.PleasesetORACLE_UNQNAMEtodatabaseuniquename.

2、尝试配置数据

oracle@sy-sp1:~>emca-reposcreate

3、报错！在安装过程多次报错，简单列举，并给出方法。

ORA-20001:SYSMANalreadyexists..
CONFIG:ORA-00955:nameisalreadyusedbyanexistingobject

4、解决方法，删除sysman用户，同时删除公共的相关表。

5、重装重配数据
