Good day, all:

I'm looking for real-life best-case scenarios for running import/export . . . I've been playing with this for quite some time and would like to know how "fast" I can really expect this to go, particularly for the import.

I'd be interested to hear others' experiences - how fast have you been able to import data? what parameters have you used? etc. . . . it's both for informational purposes and as a sanity check.

For example: I'm now trying to import a dump file of appx 6.5 Gb - breaks down into 12G data and 4G indexes.
using the following params on the first import, to just get the data (I then rerun with the indexfile param to get the indexes): recordlength=65535
buffer=15000000 (15M)
commit=y
indexes=n
constraints=n
grants=n

This will import in appx 36 hours using a single 3 Gb rollback segment

What kind of experiences have you had?

Thanks
bill
