I'm working with a customer that has Mod 4 terminals. I have a host simulation of their operations. However, when replaying this host simulation I will randomly get ECL0010 errors during replay. I have tried adjusting the timings for the host simulation with no consistent results.
There is an old existing technote that describes what I believe I am seeing: http://www-01.ibm.com/support/docview.wss?uid=swg1IC52013.
Could this a problem with Mod 4 terminals, or an issue with the implementation with the IMS system driving it?
Would it be expected to see the same result in a live connection?
