Problem:

I am receiving the message "CASKC0000E Invalid transaction ID 'trans-id', please re-submit." during a normal 3270 session, regardless of the trans-id entered.

Resolution:

Assuming the trans-id's are valid, this may be the result of certain terminal emulators incorrectly handling TN3270E data streams. In order to resolve this, the terminal emulator must be configured to emulate a base TN3270, rather than TN3270E. This change may be made at the client; however, with a large number of terminals, this may not be practicable. In such instances, the TN3270 listener itself may be configured to prevent TN3270E from being used. To implement this change, start at the Enterprise Server Administration page.

1. Click 'Edit' next to the Enterprise Server you wish to modify

2. Click on the 'Listeners' tab

3. It may be necessary to select 'All' from the 'Process' drop down in the 'Listener Display Filters' section

4. Click 'Edit' next to the TN3270 listener

5. In the 'Configuration Information' section of the listener, enter:

[Operation]

TN3270E=no

6. Click 'OK'

This change will affect any new TN3270 sessions without recycling the listener.
