Thanks Frans & [email protected] for your quick responses and
clarifications.

I am using Microsoft Windows XP Professional 32 bit SP33 OS.

I have installed - Oracle 11g Client (11.1.0.6) and ODAC for Oracle
Client (11.1.0.6.21), ODP.NET (Version -ODAC for Oracle Client
(11.1.0.6.21)) - But, i am not sure of whether this is 32 bit ODP.NET
or 64 bit ODP.NET.
_____
If there is a way to dentify whether ODP.NET is 32bit compatible or
64bit compatible please  let me know. Meanwhile i will try to figure
out the same.
_____

Also please note that I face this exception intermittently.
