Hi,
on 10g R2 on win 2003 server ,


in V$FLASHBACK_DATABASE_STAT table , ESTIMATED_FLASHBACK_SIZE is byte ? Mega bytes or else ?

I have this

SQL> select * from V$FLASHBACK_DATABASE_STAT;

BEGIN_TI END_TIME FLASHBACK_DATA    DB_DATA  REDO_DATA ESTIMATED_FLASHBACK_SIZE
-------- -------- -------------- ---------- ---------- ------------------------
24/03/10 24/03/10        2842624    1417216     718336                        87654987

Does it mean that I should have at least 87654987 on disk for db_recovery_file_dest ?

Thank you.
