I've got the UT environment up and running, but I'm at a point where I need to connect RDz to it. I've read through the zPDT volume 2 guide, and from what I can tell, I need to setup the scenario 5 networking environment. I understand the devmap setup, but not exactly sure how to change the settings in z/OS.

Also, It does not look like the RDz host component was included in the media pack. I've downloaded it and ready to get it into z/OS, but here again, I've run in the networking issue above.

I'm fairly new to z/OS, but been around linux for a while. I'm I on the right track here?

Th simple rule for UT is keep it simple. Network scenario 5 is by far the hardest and most complex to setup. If this is your first time with UT, I strongly urge you to consider another scenario for your first try. For basic TCP/IP connectivity, scenario 4 is actually the easiest to configure. The concept is that z/OS and the hosting linux each setup their own TCP/IP network with their own IP address. They share the physical network adapter through the magic of the RDz-UT OSA emulator. This allows linux and z/OS services on the same port without any special NAT routing tricks on the linux side that are required with a single IP address (scenario 5.)

As John said, scenario 4 is really easy to implement. If you are new to z/OS, follow the instructions and come back to the list when you don't understand something. Take care that you make the PARMLIB changes in the correct members, this is a place where people use to get confused and make mistakes (the docs are also very good here).
Good luck!

So, at risk of sounding like a total fool, how do I edit the PARMLIB? Also, how do I edit the TCPIP profile? As I said, I'm new to z. I understand editing data sets, but not these.

Sorry, PARMLIB is not that important for TCP/IP (but for the other configuration yes!).
I believe you are following the Redbook "IBM System z Personal Development Tool Volume 2 Installation and Basic Use", aren't you?
If you are not very comfortable with z/OS, try chapter "Setting up TCP/IP" from "IBM Rational Developer for System z Unit Test: Configuration Guide". This book shows you exactly which file to edit and which changes to do. Actually you should follow both books in parallel.
HTH,

I've figured out my error. I was not putting the user.parmlib in single quotes, and had a user.parmlib.pds. Getting the RDZ Config Guide was the missing piece. Thanks for the help!
