If you are running z/OS 1.10 on Hercules, be aware that IBM does NOT support this and could initiate legal action against you for doing so.

I suggest that TCPIP.PROFILE.TCPIP is not the data set you need to change since you are changing it and the changes are not being picked up. Look at the TCPIP started task (usually in the system PROCLIB) and determine what profile data set is being read.
