Solution Provided. 10g Infratructure Fails to Start in Reboot. opnm.exe err

Question

Hi All,
Just finished an Oracle Application Server 10g install on windows 2003 and thought I would detail an issue we had with the infrastructure.
The install runs fine and we are initially able to register the Business Intelligence servers against it. After a reboot the OracleasAScontrol service remains at a status of starting. (This is the service that runs nmesrvc.exe).
Further Symptoms are errors with the opmn.exe file. Ours would pop up and error every time we tried to shut the machine down. After we added some trusted sites we found that opmn.exe would error immediately when we logged in after a reboot.
Cause - We think this is being caused by the nmesrvc.exe (OracleoracleasAScontrol) service actually starting the opmn.exe (OracleoracleasProcessManager) service before the service has a chance to start itself. (Verified by setting both services to manual, rebooting, then starting the OracleoracleasAScontrol. Note that the OracleoracleasProcessManager starts by itself or reports the service as started.)
This seems to be causing the OracleoracleasProcessManager service not to actually run, even when set to automatic. It does however run the command to shut it down and disable the services when the system is shutdown. The problem is that even though opmn.exe is starting, the modules attached to it are remaining down because the opmn.exe -S is not running to start them up.
Services involved
Fix -
1. disable both services (Note "disable", not "set to manual")
2. Reboot
3. set OracleoracleasAScontrol to manual.
4. Select and start OracleoracleasAScontrol
5. set OracleoracleasProcessManager to manual
6. Select and start OracleoracleasProcessManager (You may get an error about process shutting down. Ignore it)
7. Set OracleoracleasAScontrol back to automatic
8. Set OracleoracleasProcessManager to disabled (And never enable it again)
9. Reboot and order shall return.
Reason.
What we found is that there are 2 parts to the opmn.
1 The opmn service which allows opmnctl to connect and start and stop individual components.
2 The control which starts and stops the components.
If you just start and stop opmn as a part of the OracleoracleasAScontrol then there is no need to start and stop the components. It also says in the manual that if you stop the compnents you must start them again as opmn will not start them automatically.
On our system it looks as though the OracleoracleasProcessManager is trying to do both of these parts and the OracleoracleasAScontrol is also including the 1st part. This duplication means that the 2nd part is running at shutdown but not at startup due to the OracleoracleasProcessManager assuming that it has already been run (We think it looks at the opmn.exe process). This then leaves the opmn.exe running but the components remain down.
We hope this may be useful should anyone come across the same problem.

Hi,
I am facing exactly the same problem after installing OracleAS 10g Infrastructure. Whenever I restart my machine I get the opmn.exe error messages and it don't go away. The other thing is that the memory usage behaviour of "opmn.exe" is strange. It is utilizing 100% cpu and the memory taken is 1.36 Gb. I have to stop and restart it.
I tried the fix, which you provided but it is not working with me. Still I get the opmn.exe error.
Actually I want to install "Portal" component on it and I am stucked by this problem in Infrastructure.
Any Idea as how to solve this problem?
