Well, recovery after resetlogs is a complex issue. For one DBID changes
after resetlogs and you end up with a different database. It would require
playing around with set dbid=.....
Common wisdom says that there is no recovery after resetlogs, and that is,
of course, false, but recovery after resetlogs is something I've been taking
all precautions against and I've never done it. One doesn't want to perform
"alter database open resetlogs" automatically unless he or she is 300% certain
that the operation will succeed. Of course, the first thing to do after
resetlogs
is - backup.
