java array insert vs. batch

All,

o/s = CentOS
db = 9.2 and 10.2
driver = jdbc (thin)
platform: two (2) dual core xeons 32-bit 2G ram local storage raid-0 (I know, I know)

Target Outcome:
insert records as fast as possible w/ java proggy

• What is the difference between batching and array inserts?
• Are array inserts in fact available for jdbc thin client?
• If somebody could provide a code sample of array insert via java/jdbc, I would sure appreciate it

Currently the best I can do w/ sqlldr (as a benchmark) is about 3K recs/sec (sqlldr invoked on db machine itself). java proggy (making net connection) is handcuffed at about 2K inserts/sec

Thanks for any, all suggestions.
