Leng,

I saw a couple replies on this, but they either referenced things out on the
internet or what-not, and I'm answering this while disconnected (stuck in an
airplane on ground-hold for weather, dammit!)...

The wording of your question implies that you want the information prior to
archiving, but if that is not the case, summing the two columns BLOCKS times
BLOCK_SIZE in V$ARCHIVE_LOG should be pretty good.

Hope this helps...
