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?

Win Home versions are not certified for Oracle database installs - Oracle Database Preinstallation Tasks

so expect such issues. Is there a reason you cannot use a supported OS version ?

After powering up the laptop, is the database up and running ? You will have to start up the database and listener before you can access the EM Express page - Getting Started with Database Administration

Hi Srini,

I have also installed Weblogic 12C, and the Weblogic em is working fine as expected. Not sure why the issue comes with Oracle EM only

Possibly because you are using an unsupported version of the OS

I installed 12C Enterprise on my laptop that has Windows 7 Home .The installation process went fine and I was able to connect to http://localhost:5500/em (even used). But, once I powered down my laptop and brought it back up the next day, I couldn't connect ('the page cannot be displayed'). So, I uninstalled oracle and then tried the process again. I could initially connect to 5500/em but after rebooting or powering down the machine, I could not find http://localhost:5500/em.




Can anyone direct me to some specific documentation with this or has anyone conclusively solved this problem to the end????? Thanks for any help.

Shouldn't you be in connecting to HTTPS instead of HTTP(http://localhost:5500/em) OR it is just a typo?

What if you try

https://localhost:5500/em
