各位请帮忙，谢谢，<br />AIX下，安装RAC，建库完成，<br />其中一台执行gsdctl start成功<br />另外一台gsdctl start失败。<br />请问为什么？<br /><br />问题解决了，重新安装了一下oracle。不知道为什么好了。<br /><br />但是新问题出来了麻烦大家帮助我：<br />ora-00481错误如何解决？<br /><br />安装Oracle RAC在AIX52，HA5.1上，安装，建库都没有错误，但是无法同时启动2个instance，只能启动其中一个。无法启动的那个Instance的错误报告如下在alert.log文件中：<br />ORA-00481 LMON process terminated with error。<br /><br /><br />哪位GGJJ碰到过？如何解决的啊？<br />由于无法去metalink如果哪位在metalink上有相关的解决方法，麻烦你Copy&amp;paster一下在下面，真的非常感谢了。

自己顶一下。呵呵，不好意思，没有办法。

嘿嘿，aix的系统、rac环境——没有metalink帐号？ 不敢相信啊？<br />大型环境最好还是找专业的公司来做维护——我说的可不是oracle……<br /><br />Doc ID:  Note:3149370.8 <br />Subject:  Support Description of Bug 3149370 <br />Type:  PATCH <br />Status:  PUBLISHED <br /> Content Type:  TEXT/X-HTML <br />Creation Date:  16-FEB-2004 <br />Last Revision Date:  26-MAR-2004 <br /> <br /> Click here for details of sections in this note.<br /><br />Bug 3149370  ORA-481 / instance crash possible from LMON<br /> This note gives a brief overview of bug 3149370. <br /><br />Affects:<br />Product (Component) Oracle Server (Rdbms) <br />Range of versions believed to be affected Versions &lt; 10G  <br />Versions confirmed as being affected 9.2.0.4 <br /> <br />Platforms affected Generic (all / most platforms affected) <br /><br />Fixed:<br />This issue is fixed in 9.2.0.5 (Server Patch Set) <br />10g Production Base Release <br /> <br /><br />Symptoms:<br />Instance may crash <br />Error may occur <br />ORA-481 <br />Related To:<br />RAC (Real Application Clusters) / OPS <br />Description<br /><br /><br />LMON may hang in name service lookup and eventually cause<br />an instance crash with ORA-481.
