I believe that there are valid reasons for the need to use LGWR ASYNC ,
Maximum Performance mode, instead of Maximum Availability mode even in
11g.
When there are wide fluctuations in redo volume and the bandwidth is
grossly inadequate for the peak volumes, I would even consider ARCH.
What criteria would you use to qualify a DataGuard environment to run
ASYNC, Maximum Performance ?
