Cannot enable Transactions using ODBC Adapter from a .NET based product to an Oracle 11g db

shyju_gsFeb 19 2015 — edited Feb 20 2015

Environment details:

1. 64 bit Windows Server 2012 R2 machine

2. 64 bit .NET application using ODBC connection to connect to an Oracle 11g db

3. Oracle Server is also 64 bit.

Installed 64-bit ODAC 11.2 Release 5 (11.2.0.3.20) for Windows x64 components from

http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html

P.S.: the Oracle Services for MTS was checked during installation.

Created an ODBC DSN using the ODBC Data Source Administrator (64-bit). This is used in the .NET application to establish connection to the oracle db.

Connectivity works fine if i do not enable transactions, but if i enable transactions i get this error:

ERROR [HY000] [Oracle][ODBC]MTS support not available, could not load ORAMTS.DLL

I see there are lots of discussions around this topic, i have tried everything but nothing has worked. I always end up with the same error.

Can someone suggest what can be done to troubleshoot this issue?
