Re: Determining the "fuzziness" of a datafile

Adam,

in V$BACKUP_DATAFILE, I think you can use the column ABSOLUTE_FUZZY_CHANGE#. Regards

Selon "Donahue, Adam" <Adam.Donahue_at_kbcfp.com>:

 Folks,

 Is there an easy way to determine exactly the "fuzziness" of a datafile  that's been restored from an RMAN back up as part of a clone operation
(meaning with a backup controlfile), without having to look at the
 backup catalog itself?

 That is, as far as I can tell, when a backup at time 0 is started and  completes at time 100, the blocks of the files backed up in that period  could reflect anything from 0 to 100 depending on when they were read.  And of course we need to redo containing those changes. But v$datafile
(and v$datafile_header), as well as v$database, don't give an indication
 of exactly how much redo is needed to bring the database back to a  consistent state. Is there a way to say "What's your max (or min) SCN?"  or is this a lower-level operation that would require tracing. I figure  it must be somewhere - but I didn't see the SCN noted anywhere upon a  cursory glance.

 Adam
