能否正常启动OEM或OMS关键有以下两点:
第一.Oracle的系统服务是否开启;
第二.登录时用的用户名和口令是否正确。

   那么先针对第一点谈谈Oracle的系统服务。在完全安装的情况下,Oracle的系统服务共有11项:
   1.Oracle   OLAP   9.0.1.0.1
   2.Oracle   OLAP   Agent
   3.OracleOraHome90Agent
   4.OracleOraHome90ClientCache
   5.OracleOraHome90HTTPServer
   6.OracleOraHome90ManagementServer(0.5M)
   7.OracleOraHome90PagingServer
   8.OracleOraHome90SNMPPeerEncapsulator
   9.OracleOraHome90SNMPPeerMasterAgent
   10.OracleOraHome90TNSListener(5.2M)
   11.OracleServiceORACLE(70M)
           (注:OraHome90是可以在安装时改变的Oracle的主目录名称,是安装时的默认值)
  
其中最重要的服务有3个,分别是OracleOraHome90ManagementServer、OracleOraHome90TNSListener与 OracleServiceORACLE。
下面就来看一下有哪些启动错误与它们有关。
1.Oracle系统提示:Ora-12541:TNS:没有监听器;
2.操作系统提示:在本地计算机无法启动OMS服务
                 错误:1053:服务并未及时响应来控制请求附带;
以上两种错误提示大都是由OracleOraHome90TNSListener监听服务引起的。
解决方法:控制面版-> 管理工具-> 服务-> 右键单击“OracleOraHome90TNSListener”,再单击“启动”。

3.Oracle系统提示:Ora-12500:TNS:监听程序无法启动专用服务器进程;
该错误是由OracleServiceORACLE专用服务器进程引起的。
解决方法:控制面版-> 管理工具-> 服务-> 右键单击“OracleServiceORACLE”,再单击“启动”。

4.Oracle系统提示:VTK-1000:无法连接到Management   Server。
                                      请验证您已输入Oracle   Management   Server的正确主机名和状态。
该错误引起的原因有两种,一是OracleOraHome90ManagementServer还没启动;二是没有输入主机名。
解决方法:控制面版-> 管理工具-> 服务-> 右键单击“OracleOraHome90ManagementServer”,再单击“启动”,
或是输入您这台计算机的完整名称。


接着针对第二点谈谈登录时用的用户名和口令。

在安装结束后,系统提供了两个默认的数据库系统管理员,其用户名和口令分别是SYS/change_on_install和SYSTEM/manager,
同时系统还提供了登录OMS的用户名和口令:sysman/oem_temp。这里容易出现错误的是在登录OMS是用SYS或SYSTEM作为用户名进行登录,
那么Oracle系统就回有“登录身份证明不正确”的提示。

小结:这三个服务的启动或关闭还有先后的顺序。
一般来讲,,启动时必须先启动 OracleOraHome90TNSListener
再启动 OracleOraHome90ManagementServer 或OracleServiceORACLE,
在启动OracleOraHome90ManagementServer时,同时也启动了OracleServiceORACLE。

而关闭时必须先关闭OracleOraHome90ManagementServer
再关闭OracleOraHome90TNSListener或OracleServiceORACLE,
关闭OracleOraHome90ManagementServer时,若有提示输入用户名和口令,请输入sysman的用户名和口令,以确保成功的执行。

有些其他提示如:资源已被占用,I/O重复,端口已被使用等等之类的话,那最好与系统管理员联系,再寻求解决办法。
