Oracle中OEM的启动与关闭

我已经选择安装了，但安装后发现开始菜单里并没有OEM，在哪里可以打开呢？

从Oracle10g开始，Oracle极大的增强了OEM工具，并通过服务器端进行EM工具全面展现。
在10g中，客户端可以不必安装任何Oracle客户端工具，仅凭浏览器就可以调用强大的EM工具。

在一些时候我通过查看portlist.ini，来确定安装oracle打开那些端口来启动相应的服务，可以通过此文件确定

$ORACLE_HOEM/install/portlist.ini

2.下面主要介绍dbconsole的启动与关闭

在Server端，可以通过如下命令启动EM工具控制台:

emctl start dbconsole

启动之后我们就可以通过在浏览器端输入以下url访问:

同样停止OEM可以输入如下命令:

emctl stop dbconsole

以下是停止过程:

[oracle@danaly ~]$ emctl stop dbconsole
TZ set to PRC

Stopping Oracle Enterprise Manager 10g Database Control ......  Stopped.

也可以直接键入emctl查看emctl支持的选项:

[oracle@danaly ~]$ emctl

启动EM
要确保OracleDBConsole<SID>服务已经启动。
启动服务：emctl start dbconsole
关闭服务：emctl stop dbconsole
访问EM：http://服务器名称或IP地址：端口号/em
端口号可在$ORACLE_HOME/install/protlist.ini中找到

错误分析

在Windows下的命令行窗口输入emctl可以查看emctl支持的选项，但是输入后回车，提示如下：

Environment variable ORACLE_SID not defined. Please define it.

说明环境变量没有设置SID，在当前窗口中临时重新设置如下：

C:\>set ORACLE_SID=orcl
C:\>emctl
Oracle Enterprise Manager 10g Database Control Release 10.2.0.1.0
Copyright (c) 1996, 2005 Oracle Corporation.  All rights reserved.
Invalid arguments

Unknown command option
Usage::
Oracle Enterprise Manager 10g Database Control commands:
emctl start| stop| status| setpasswd dbconsole

emctl blackout options can be listed by typing "emctl blackout"

emctl secure options can be listed by typing "emctl secure"

上图说明我们可以正常使用emctl命令了，下面就可以启动或停止dbconsole服务了

C:\>emctl stop dbconsole
