First let me apologize for asking this question as it is only somewhat
related to NB.  We are in the process of implementing EMC BCV to backing up
an Oracle database (500GB).  I was told that you could create a BCV while
Oracle is live (no shutdown or hot backup mode required) and I agree with
this statement.  What I am not sure of is can you roll-forward with this
BCV.  For example, at 1:00, you snap your BCV and the production Oracle
continues to run (no stoppage).  At 4:00, something bad happens to
production Oracle.  You restore your BCV on top of production, can you
roll-forward the production logs up to 4:00?  The reason I am puzzle is
because when you snap the BCV at 1:00, the Oracle database (BCV) is
startable but will go into recovery mode.  It will rollback in-flight
transactions.  Can you apply the production logs to this database to bring
it to 4:00?

Thanks,
Ken
