I'm starting to work on TCPIP on my 2nd level install system and have
come across a warning in the Program Directory for TCPIP. In section
5.2.4.2, there is a bullet item that says:
* This level of TCP/IP relies on the presence of certain functions
in the z/VM version 5 release 4 levels of CP and CMS. The
converse is also true--using z/VM version 5 release 4 CMS requires
that TCP/IP level 540 be present, to accomodate those functions
that use TCP/IP (DNS) resolver services.
Abends and incorrect results are possible if you attempt to
use mixed levels of TCP/IP, CP and CMS.
I have occasionally come across situations where a sub-system such as
TCP/IP requires a matching level of CMS but a matching level of CP is
very unusual. I don't like doing "big bang" conversions. I would like
to be able to move the 5.4 level of CP from my 2nd level install system
to my test lpar and then move the 5.4 level of CMS and then the 5.4
level of TCP/IP and some other things. In this case, the bullet item
specifically mentions that a CMS/TCPIP match is needed for DNS resolver
services. We run DNS on a different system.
I would appreciate some thoughts on the idea of mix and match.
