racgimon.exe CPU usage question

Hi,

 

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

 

SQL> select version from v$instance;

 

VERSION

-----------------

10.2.0.1.0

 

SQL> select * from v$active_instances;

 

INST_NUMBER INST_NAME

----------- ----------------------------------------

          1 DEVWIN16:winracdb1

          2 DEVWIN15:winracdb2

 

 

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 then manually created an empty file
F:\oracle\product\10.2.0\db_1\opmn\conf\.formfactor, but that did not
help. Now when I look at Filemon log:

Does anyone encounter similar situations? And is it normal that they
take that level of CPU usage?

 

Thanks.
