Re: Standby abuse

I agree with Dominic,physical standby db files will be useful while
you make some recover task, Logical standby can not support
bfile,rowid, user defined types, and some types in the table which you
can not distinguish by rows,
if your database do not contain those object which not be supported by
Logical standby,
you can also try logical one.

And the new feature of 11g is that it can provide read ability while
still applying the logs,
that means in 11g, physical standby db can also provide you for read access.
