I'm interested in point-in-time-recovery (or archive recovery) too.
I'm wondering current implementation of CHECKPOINT is whether "SHARP"
or "FUZZY" checkopint. If it's a "SHARP" one, it would be a serious
performance bottle neck according to the Gray's transaction book. Does
anybody know anything about that?
