oracle logical standby

[Loughmiller, Greg]

folks - listening to a preso from a vendor where they will use logical standby to accomplish some of the 99.999999999999999 availability requirements... so I'm wondering, does anyone have some extensive experience with the logical standby to share? the good stuff, the bad stuff, pitfalls, gotcha's, and general things to run away from.. Then on the other hand-what things should someone try to leverage?   thanks in advance!   Greg Loughmiller
