在Windows 操作系统下安装Oracle 9i时会安装很多服务——并且其中一些配置为在Windows 启动时启动。在Oracle 运行在Windows 下时,它会消耗很多资源,并且有些服务可能我们并不总是需要。你会发现不使用Windows 图形界面就可以快速、完全地关闭数据库会很有用。

只要拥有管理员权限就可以通过net start 启动一个服务,或者通过net stop 命令停止一个服务,从而控制以下服务中的任何一个。在Windows XP 中,可以通过在控制面板的服务中改变想要禁用的服务(OracleOraHome...)的启动类型(Startup Type)参数,双击某个服务查看其属性,然后将启动类型属性从自动改为手动。

使数据库在本地工作唯一需要运行的服务是OracleServiceORCL 服务(其中ORCL 是SID)。这个服务会自动地启动和停止数据库(使用shutdown 中断)。如果安装了一个数据库,它的缺省启动类型为自动。如果主要是访问一个远程数据库,那么可以把启动类型由自动改为手动。

  • OracleOraHome92HTTPServer 服务(OraHome92 是Oracle Home 的名称)是在安装Oracle 时自动安装的Apache 服务器。一般情况下我们只用它来访问Oracle Apache 目录下的Web 页面,比如说JSP 或者modplsql 页面。

  • OracleOraHome92TNSListener 服务只有在数据库需要远程访问时才需要(无论是通过另外一台主机还是在本地通过 SQL*Net 网络协议都属于远程访问)。不用这个服务就可以访问本地数据库。

  • OracleOraHome92ClientCache 服务缓存用于连接远程数据库的Oracle Names 数据。正常情况下该服务的启动类型是配置为手动的。然而,除非有一台Oracle Names 服务器,否则没有必要运行这个服务。

  • 有四个服务是Oracle 企业管理器所必须的(Oracle Enterprise Manager),这些服务分别为:OracleOraHome92Agent(智能代理),该服务监视数据库和企业管理器请求,缺省启动类型为自动。OracleOraHome92SNMPPeerEncapsulator 和OracleOraHome92SNMPPeerMasterAgent,处理安全网络管理协议服务。OracleOraHome92PagingServer 通过一个使用调制解调器的数字传呼机或者电子邮件发出警告。

  • OracleMTSRecoveryService 是可选的,该服务允许数据库充当一个微软事务服务器、COM/COM+对象和分布式环境下的事务的资源管理器。

  • 如果只是偶尔使用一下数据库,那么可以创建一个简单的脚本任务来启动和关闭服务器,这样每次只要双击脚本就可以了,可以不使用图形界面。

    1. 保存一个快捷方式自动地装载这些文件。

    2. 将Oracle 服务设为手动避免在Windows 启动时启动。
