MTO SESSION

We can't diagnose the problem without more information.

What product, version, and platform are you using?

When you say "ACCT server", do you mean you're trying to do the Debugging Tutorial in the product documentation? If not, where did the configuration for this server come from?

One possibility is that the server is not configured for MSS (mainframe emulation); another is that you do not have a license for MSS. But without product, configuration, and diagnostic information, we can only guess.

Note that the product documentation includes a long discussion on how to diagnose issues.

Hi Michael,

I am using MF enterprise server Developer edition.  I imported the ACCT sample project into my work space and ACCT server started. I try to connect to the MSS ACCT. I used Vista 3270 emulator. it gives the MTO session not available. I used the Quick3270 emulator, it says unable to connect to port 5239.  The ACCT server has 5239 port as listener. why it is not connecting to it. The license says I have 18 days left.

I still need to know the product platform and version. Enterprise Developer for Windows or UNIX? If it's Windows, is it for Visual Studio or Eclipse? And what version of the product?

For the ACCT sample, I recommend you follow the CICS Tutorial in the documentation (Welcome > Getting Started > Mainframe Tutorials > Tutorials: CICS > Tutorial: CICS), rather than simply trying to import and use the project.

Beyond that, I can't diagnose a problem with your server without diagnostics. I would at least need to see the server's communications log. I'm not sure how you'd view that, since I don't use the IDE to interact with ES regions (and I don't even know which IDE you're using).
