Patching with OPatch when Oracle10G UI is installed

[rado]

Hi All,
I have an 9.2.0.4 database which I am trying to update with the new patch (for security alert #68) on Windows 2000.
But when I start opatch.pl with perl.exe the I am receiving the following java error:

Checking if this is a RAC system...

Exception in thread "main" java.lang.NoClassDefFoundError: oracle/xml/parser/v2/
XMLNSNode

iiiInstallAreaControl.java:533)

allAreaControl.java:582)
...............
etc.

d:\opatch\opatch.pl version: 1.0.0.0.43

Cannot set up OUI inventory session

I think that the problem is the newer version of the Oracle Universal Installer - 2.3.0.1.0 (from Oracle 10G Installation CD)
On some other PC I have the same problem with the same version of OUI.
But the installation was successfull on all other PCs, which have oldest version of OUI.

Any suggestion how to relocate java classes to look in older version of OUI will be very helful.
Or of course some suggestion for other workarounds.

open a tar and demand an odc oracle direct connect and let them patch it for you, also complain to the duty manager - optach is such crap
