I don't want to rent Mark's thunder (can't afford it), but I remember some
quirks of DR before we had the CFRM policy pre-installed at the first IPL.
RACF came up in non-data-sharing mode, but there were no consequences aside
from a little kvetching. Hey, if you can drag your kid through a
supermarket checkout line without caving in to unreasonable demands, you
can ignore software sniveling a while about trivia until SOP is reinstated.
After the CFRM policy is established and structures can be allocated, RACF
can be told to resume data sharing. Being READ-ONLY at the start of DR in
an uncertain state is not such a bad thing. Probably a bad time to be
making updates anyway. ;-)

This parm has been around (at least) since OS/390 2.10. Came in very handy
when the big DR requirements started.
As for JES2 checkpointing in the CF: We only had it in the sysprog
sandplex, and that one got deactivated along with the CFs rather
frequently, resulting in an automatic checkpoint reconfig dialog at
restart. I finally took it out of the CF, as we never got around to rolling
JES2 exploitation out into production.
Mark,
Out of curiosity: What's the problem with RACF datasharing? We do that,
too, and never had a problem with fresh CFRM policies.

Something to keep in mind if we ever have to get rid of the box in the
other location that we use for DR.
