Re: Dataguard in data warehousing

I believe Data Guard can handle the load, I have worked on a database recently where the archive generation rate is about 4-6TB a day, the maximum gap was only about 10-15 minutes and most of the time about a minute. so on an average 170 - 256 GB a hour, provided you have necessary bandwidth at the IO/network layer i dont think you will have any issues.

Thanks,
Vishnu
