racgimon.exe CPU usage question

Hi,

We have 2-node oracle rac db on window platform.

Oracle Clusterware was upgraded to 10.2.0.3 with "10g Release 2 (10.2.0.3) Patch Set 2 for Microsoft Windows (32-Bit)"

The problem is that while the rac db is up and running (but with no db activities from any applications), we found racgimon.exe is taking about
15% cpu usage, followed by ons.exe of about 10% cpu usage.

Using a tool called "Filemon", we found racgimon.exe is trying to write to a file called F:\oracle\product\10.2.0\db_1\opmn\conf
\.formfactor.

The file isn't there and the exe just keeps trying to open it... over..
and over..

I worked on this issue a bit more, found a workaround, but still hope that I could resolve this issue completely.

In SOFTWARE\ORACLE\KEY_OraCr10g_home,

    ORACLE_CRS_HOME C:\oracle\product\10.2.0\crs     ORACLE_HOME C:\oracle\product\10.2.0\crs

In SOFTWARE\ORACLE\KEY_OraDb10g_home,

    ORACLE_HOME f:\oracle\product\10.2.0\db1

F drive is the drive that gets shared by two nodes.

To workaround the above issue, I need to do

copy each node's file C:\oracle\product\10.2.0\crs\opmn\conf
\.formfactor to F:\oracle\product\10.2.0\db_1\opmn\conf\.formfactor on
the shared F dirve,
and then I can see racgimon's CPU usuage drop to close to zero on each node.

My guess is racgimon daemon is not taking $oracle_home as C:\oracle
\product\10.2.0\crs (which it should), but it takes F:\oracle\product
\10.2.0\db_1 as $oracle_home. I tried to change $ORACLE_HOME for css
by running

cd C:\oracle\product\10.2.0\crs

localconfigure reset "C:\oracle\product\10.2.0\crs" on devwin16, but never succeeded.

Below is what I got:

C:\oracle\product\10.2.0\crs\BIN>
C:\oracle\product\10.2.0\crs\BIN>localconfig.bat reset "C:\oracle
\product\10.2.

0\crs"
Step 1: stopping local CSS stack
  failed to stop CSS service, err(1051)
  failed to delete CSS service, err(1072)   failed to delete the local CSS stack
Step 2: deleting OCR repository
Step 3: creating new OCR repository
Successfully accumulated necessary OCR keys. Creating OCR keys for user 'crdhome\gmei', privgrp ''.. Operation successful.
Step 4: creating new CSS service
  Failed to create the new CSS service, err(1072)   failed to create new CSS services

Any suggestions?
Thanks.
