I am interested too, as I'm using Rails with DB/2 as part of my job.

This is a great feature. Is any modification needed to benefit from this
from say a C app written to the CLI, or is this an external configuration?
We've been handling failover manually, and this would make our lives that
much easier.

Apart from improved Ruby drivers, the Rails adapter needs some work too.
In particular, DB2's inability to limit rows returned from a query to a
range needs to be worked around by using subqueries. It would be great to
be able to have top-notch DB/2 support out of the box.

Bye,
	Andrea
