[OverflowException: Arithmetic operation resulted in an overflow.] 
System.IntPtr.ToInt32() +37 
CoreLab.Common.a.a(Delegate A_0) +1935 
CoreLab.Oracle.ab.a(OracleConnection A_0) +214

This looks like some poorly written unmanaged interop code which doesn't take into account the CPU type and which blows when run in a x64 bit OS. In a 64-bit OS pointers are 64-bit integers contrary to 32 bit OS.

Maybe you should check the documentation of this CoreLab.Common component you are using whether it supports 64-bit systems.

Quote from the documentation of the IntPtr.ToInt32 method:

OverflowException: On a 64-bit platform, the value of this instance is too large or too small to represent as a 32-bit signed integer.

Yes. Currently i am using 64 bit OS ..This might be the culprit.

Darin Dimitrov Over a year ago

The culprit is the component you are using not being compatible with a 64 bit OS.

Ravi Over a year ago

Ok.Thanks. I installed 32 bit corelab component.

Ravi Over a year ago

But i am not able intsall Oracle client 64 bit component on 64 OS . Any idea? Thanks in advance
