Re: Dataguard / Archive Logs

Hi,

I have a couple more questions on this as its getting quite involved
here as to how we are going to set it up.

Still in the planning phase here and what we have is the primary and
seconday site each with its own SAN.

The SAN's are connected via a fibre link wihich have their own
transfer protocol between them.  At the moment there is no standard
network connection available between the two sites for us.

As the data gets written on the primary, the SAN is replicating that
data automatically to the standby site so in theory they are the same

so all being well can we then take that archive log and apply it
manually to the standby database.

Is this a known configuration? =20

This is going to be harder to do a test on, so if anyone knows I would
be extremely grateful
