With storage as cheap as it is now I’d consider a switch to a physical standby
and do a clone/rename after pausing recovery at the time they want. (This has
worked since v6.0.37 or so.)
It also seems like a fine use case for Delphix technology, particularly if you
might want several generations (different points in time) available at the size
of one copy plus n likely small deltas instead of n full copies. (Disclosure: I
have several friends there who I consider “peers of the realm” vis-à-vis Oracle
technology, but no financial relationship.)

Hi,
Our DW team has had a Logical Standby of the OLTP database they get their
data from for years now. Each night, the SQL Apply on the LS stops and they
get a point in time view of transactions for the day. This has been a pet peev
of mine since i've started working at my current job. I'd like to change it
and i thought that Oracle Flashback Query in the Primary database would get me
what i want. In our testing we've been running into ORA-01466 errors often
enough where we could see it being a problem with an actual implementation of
our current new configuration of this work.
Does anyone have a better way of getting what the DW team needs on a daily
basis then what i've described? All they really need is a Point-In-Time view.
