oops. I missed the 5-10 minute lag max SLA of the first bit of the thread.
Carel-Jan's solutions are logically equivalent to as good as you can get in
that space, I believe.
In the mid-market competition it sure seems like Oracle is stacking the deck
against themselves on this issue after they really did some excellent work
figuring out the price points and buying strategies for off the shelf deals
to beat ConvictedMonopolistSoft. My understanding was they were trying to
manage downward the cost of sales and maximize the ease of purchase, so
trying to manage negotiations for folks in this space that want site
disaster business continuation is probably not a scalable or profitable
option.
I wonder whether the putative consequent reduction in sales costs Oracle
more money than would giving away DataGuard or the like for classes of
machines for which the SE offerings are valid. Then again, I've not done a
market size study in that space: Small total horsepower required, but needs
business continuation/reporting.
At least I'm getting good at snip and cut-and-paste address....

Standby in all appearances (except Logical Standby, but that is EE)
tends to be in recovery mode. So, there is quite few read-only access
possible to the second database, which happened to be the original
question. I don't think that opening and closing the database in
read-only/recovery mode every five minutes will come close to the SLA
that running the reports needs.
