Hi Guenadi,
Yes, it is temporary and a once-off. This has merit.. I hadn't
considered it even. As I understand, as long as the standby is
completely synchronised, the replicats should in this scenario simply
pick up at the point where they left off? If so, there should be no need
even to stop datapump or extract on server A when NFS mount from B to C
is used, should there?
Cheers,
Tony
