Hi Jaffer,
Data guard is exceptionally good option, except it depends on the
protection mode using(for data loss).
Streams concerned, as far as my knowledge its a replication mechanism&
maintenance is a bit problematic thing when compared with data guard.
Thanks,
Sandeep

Subject: Data Guard vs Streams for a RAC database
Good day everyone,
We are in need of preparing a backup server for one of the business
critical RAC databases at our company. Since the DRC setup will take
some considerable time, application owner requested to maintain a backup
database server (active) for the database to be able to survive from any
scary incidents. Although my vote goes to Data guard configuration, we
would like to choose the best and a very light weight option to fulfill
the requirement. Any pros and cons or comparision between these two
would be highly appreciated.
