This problem stops me start database 10g on Windows XP. I am wondering
anyone might have same experience before and could share how to fix the
issue. Here is situation:

Every time when 10g database starts, a process java.exe which loaded by
nmesrvc.exe (I think it is OracleDBConsoleMyInstance, right?) uses 89%
cpu forever. Because of this, OEM couldn't work! Shutdowning the
database and restarting it didn't solve the problem. Killing
nmesrvc.exe can stop the java.exe. SQL*Plus still works. But
iSQL*Plus didn't works.

If I stop process OracleDBConsoleMyInstance from Services of Windows, I
got error: Error 1053.

What is wrong here. Your help will be appreciated,
