I don't know what an ICA is in this context, but your note rang a bell.
When the folks I work with configure a (modern) machine to be used for
TPF, they include this feature code.
8P2980 OSA ICC- 3215 Enablement (this one for a z15)
I've been told this is needed for TPF console processing, although I
don't know the details. 8P2980 costs money so it's not configured on
machines we work with that don't run TPF.
