Hi All,

Can you please kindly clarify the following doubts on
snapshots:

 we have got around 50 snapshots to be created on same
database from 1  schemas 2 another readonly
 majority of these  snapshots access same base tables
1) can I  refresh them parallely? At a time Howmany
can I refresh parallely?
 When I tried to refresh paralley DB hang and  refresh
time took  4  times more than normal time
DO I need to increase the follwoing parameters?
job_queue_interval                   integer 60
job_queue_processes                  integer 4

2) I need a consistent view when I refresh all my 50
snapshots, so total time might take 2 hours, meansm
while some other tables might get updated, SO when I
want  consistent for all my 50 snapshots, can I use
set transaction readonly?

Please kindly clarify me

with regards,
John.
