From A, it tpacall Service B. TpgetR from B, it returns "12 An internal system error has occurred in OLTP" at first. And then it all returns "2 Invalid comm handle was specified on a TPGETR". What does it mean? Thanks a lot.
Well it sounds like the tpacall() didn't succeed and thus the returned handle wasn't valid, although it's a little hard to follow exactly what you've posted. Could you provide a bit more detailed explanation?
