Joerg, of course i was referring to manual standby, and yes you'll need to
weigh up the cost of managing this yourself against the cost of automating it
using dg, that said most se customers will be manually managing things like
performance, alerts and so on and so on these days - now that the performance
tab of em etc isn't available to them. I don't honestly see why a manual
standby is such a big deal now oracle has largely abandoned making management
functionality available to them.
