Phil,

I agree with your point completely, however on other platforms they are very
comfortable with spinning up a copy of the DBMS on a backup LPAR to
rollback/commit the database entries and then do the backup on a clean
database. I'm sure a similar method would work on MVS with DB2.

There is still the problem of 2-phase-commit and associated metadata. Your
DB2 database may be nice and clean, but what about your associated
CICS/VSAM, IMS, CA-IDMS or Adabas files? I'm not aware that they have a
similar Log Suspend function to DB2, and the mind boggles as to how it would
be coordinated across each DBMS and file systems to produce federated
consistency. That's why I like timestamp and hardware based consistency more
than software driven.

Anyone working with federated transactions across distributed databases in
Client/Server land will know what a let-down software based consistency can
be.
