1. Yes, VTAM will talk across the 'sysplex' CF structures in a parallel
sysplex. We discovered this early on more or less by accident. You also
have the option of 'VTAM generics' via a separate CF structure.
2. CTCs are not required in a parallel sysplex, but every discussion I've
ever seen on the topic strongly recommends them as a backup mechanism. If
CF communication fails or gets severely interrupted, the CTCs provide an
alternate method of communication. You may be hosed anyway, but at least
you'll go down with a few salient messages to ponder.

This relates to my previous question about Parallel Sysplex. I'm trying
to read the books quickly to get a "Power Point" presentation ready.
IIRC, the VTAMs can talk to each other via XCF instead of/in addition to
CTCs if they are all in the same sysplex. Correct?
Second question: a Basic Sysplex connects with CTCs. Do I need CTCs in a
Parallel Sysplex or does the CF entirely replace the CTCs?
Many thanks from a very Sysplex ignorant person.
