Yoooooo Rancher, First off, congrats for the memory upgrade. My scenario: I am dealing with Adabas database, if you've heard of, and the dopey vendor does NOT supply the JDBC compliant drive for it (don’t mention Jadabas cause it aint a driver). The only vendor that carries the driver asking beyond what our org. can afford. My question for gurus and SEs is, how difficult is it to write a JDBC driver that can run on Zzzzzzzzzzzzz machine (OS390)? On the scale of 1 – 10, 10 being the most difficult like installing ms windos, and 1 being as easy as using JDBC driver.
