I have 4.5TB database and need to make copy of it to test environment. But I
don't need to bring all the data to the duplicated copy. The production
database has data for last 20 years and I would like duplicate with last 5
years data.
Is it possible to duplicate a database with a subset of the production data
using RMAN duplicate feature?
If not then what are the other options?
Thanks,
Ashoke Mandal
