Applies to:

Oracle Server - Enterprise Edition - Version: to - Release: 10.2 to 10.2
Microsoft Windows (32-bit)
Microsoft Windows x64 (64-bit)
Microsoft Windows


In the README of the Windows patchsets you find a step to patch the orafence driver:

"Stop Oracle Service OraFenceService, and take a backup of file orafencedrv.sys located under %s_systemDirectory%/drivers, replace it with the one supplied in the patch under..."

Sometimes this step is missed during the patch apply. To run with an old version of the driver might result in node evictions and system instability. If you experience this you should check that your orafence driver is the one that you should be run with your patch level.
