Hi, Oyvind, you may have already done this, but can you linke this to

>Currently, the Embedded Driver supports Statement.setQueryTimeout(), but the Client Driver
does not. The Client Driver should be enhanced and match the Embedded Driver.
>For this, we need to transfer the timeout value from the client to the server, preferably
without a separate round-trip. I have some loose thoughts on how to do this:
>* If the client has set a timeout value for a statement, prepend the (DRDA) EXCSQLSTT
command with an EXCSQLSET command which contains the timeout value; conceptually a "SET STATEMENT
TIMEOUT <seconds>" (this does not mean that we need to extend the Derby grammar; only
the Network Server needs to understand this DRDA EXCSQLSET command).
>* In DRDAConnThread.parseEXCSQLSETobjects() on the server side, recognize the "SET STATEMENT
TIMEOUT" text, parse the timeout value and remember it for the coming EXCSQLSTT command. Do
NOT invoke executeUpdate() with the SET statement [see note below].
>* In DRDAConnThread.parseEXCSQLSTT(), check if a timeout value has been set; if so, use
it (by setting the timeout value on the server-side Statement object before calling execute/executeQuery).
