Hi tj, There is a role change action script in the geo edition. here you can put any script you need.
There a simple example for a DNS update in docs.sun.com. See http://docs.sun.com/app/docs/doc/819-7195/6n95isa9p?l=en&a=view&q=role+change+action+script If you haave an oter name server you have to develop the action script on your own. It is hard to predict the tim until all you name servers are populated, This strongly depends on your ns type and topology. Detlef T.J. Yang wrote: > > > > > T.J.
