Adaptive Server version 15.7 ESD #2 and later allows you to fully log bcp in fast mode, which provides faster data throughput and full data recovery. Earlier versions logged only page allocations.
bcp pubs2..titles in titles.txt --initstring 'set logbulkcopy on'
You must enable select into/bulkcopy/pllsort on the database before issuing fast-logged bcp; otherwise, bcp uses slow mode.
