Hi Limin
We're a NFS and NetApp shop, but I've never tried this as we use Data Guard for
DR. However, did you see this NetApp technical report:
http://www.netapp.com/us/media/tr-3455.pdf?
In the example, the source DB uses NFS, but off-hand I would think it should
work for ASM too. Presumably, you'd need additional steps to mount the ASM disk
groups after braking the mirror. Given that the solution involves recovering
the database from a broken mirror, you could amend the DR parameter file to
have less instances than the primary DB and once the DB is open, disable the
redundant redo threads.
Hope the helps
Austin
