Kristian Waagan commented on DERBY-2017:
----------------------------------------
I haven't looked into the details, but DRDA has a mechanism for interrupting
DRDA requests. However, this requires that the client opens a new connection to
the server to issue the request.
Without knowing how hard this will be to implement, does this sound as a viable
solution?
Interrupting the server is an exceptional case, so I guess the performance of
the mentioned solution isn't critical (i.e. create new connection, send the
request, receive reply, throw exception and do cleanup on the client side will
take a while compared to sending something on the existing connection). I
suppose we can use the same mechanism if we need to be able to interrupt the
server in other states.
For those interested, see DRDA vol 1 - 4.4.14 Interrupting a Running DRDA
Request.
As I said, I haven't yet studied the spec, nor Derby's DRDA implementation, so
I can't say for sure this will work.

> When a LOB stream throws an exception or does not match the specified length,
> the client driver does not raise an exception until it has finished executing
> the statement. Therefore, the statement will be executed (and possibly
> committed) on the server even though the client reports that the statement
> failed.
