Problem:

When TN3270 emulators connect to Enterprise Server MTO they send their model name, for example IBM-3279-2-E. The Enterprise Server MTO auto-install process maps the long model name to 8 characters to try and match against a predefined model. How can the mapping be debugged?

Resolution:

To troubleshoot the mapping of the long name to the internal one you can set the following environment variable before the CICS region is started.

ES_TN3270_MODEL_LOG=Y

When this environment variable is specified CICS will write the model name to a Temporary Storage queue named TN32MODL that can be viewed using the CEBR transaction.
