Jim - I think CTCs are required when you don't have a CF. We have CFs so this isn't an issue for us. We have used Escon in the past for CTCs. One consideration is that the zEC12 and zBC12 don't support Escon so if you plan to upgrade processors it would be best to commit to using Ficon instead of Escon. Sorry, but we have no experience doing that.
Carl retired maybe five years ago. He had a serious heart attack in about 2004 so that may have hastened his retirement. He and Susan have a camper and travel extensively. Unfortunately I haven't seen him for at least five years. We are on opposite coasts so that makes it hard. SHARE has become very small. No one has a travel budget anymore. It's still a good conference, but it's a shadow of what it once was.

We do not need the things that parallel sysplex would give us; anyway, a parallel sysplex on a single box doesn't make sense to me. We do want: .. GRS that works in a way that makes sense: cross-system ENQ, convert RESERVEs .. Shared HSM, RMM, catalogs, virtual tape. Probably NJE instead of shared spool. .. Give the developers a place to work so they don't need to log on to prod except to upgrade or fix things .. Developer tools won't run on production "Isolation" can be accomplished with some vary-offline commands in COMMND00, that allows us to vary prod volumes online to dev if we have to.
