Boy, this conversation has taken an intresting turn. :-) The question is whether DB2 Connect on Linux on System z talking via DRDA to DB2 on z/OS across HiperSockets will enjoy the same zIIP benefit as the same DRDA transaction would receive when acccessed by some other host via OSA-Express. The advice the OP received that DB2 on z/OS would treat DRDA connections via HiperSockets differently than those made via OSA is suspect. First, I don't know how DB2 could tell the difference. Second, it doesn't make sense because packets could flow via HiperSockets OR via OSA on the same TCP connection! A call to the Support Center would clarify the issue.
