David Brown commented on DERBY-5920:
------------------------------------
Thank you for the responses.
We are happy to cooperate with the Derby community in ensuring interoperability.
Where are these extensions documented, and are they considered optional or
mandatory?
If any of the extensions are of general utility (i.e. applicable to other
databases), have they been proposed as extensions to the DRDA standard by the
Open Group Database Interoperability Consortium
(https://collaboration.opengroup.org/dbiop/)?
Could you point me to a starting point for running the tests that you refer to?
I am assuming that we will initially test with the older version of the derby
server that doesn't reject our client.
Also, was there was a particular issue with the IBM drivers (e.g. data
corruption?) that influenced the decision to cut off access from non-Derby
drivers? Or was it just a matter of simplifying support?

> PRDID "SIG"

> Key: DERBY-5920
> URL: https://issues.apache.org/jira/browse/DERBY-5920
> Project: Derby
> Issue Type: Improvement
> Components: Network Server
> Affects Versions: 10.9.1.0
> Environment: Any
> Reporter: David Brown
> Labels: DRDA, SIG, StarQuest, StarSQL, client, network
>
> Background - Refer to DERBY-5565
> "Derby Network Server has been changed to reject client connections from
> clients that are not Derby Network Client (Those that do not send PRDID
> starting with DNC).
> Rationale for Change: There are currently no known supported network clients
> for Derby Network Server other than Derby Network Client."
> This is incorrect - StarQuest Ventures has a shipping DRDA-compliant network
> client "StarSQL for Java" that has supported Derby since August 2008. It is
> listed at http://wiki.apache.org/db-derby/UsesOfDerby.
> This change means that we can now only use an older version of Derby until
> our PRDID is added.
> Our PRDID is SIG - see
> http://publib.boulder.ibm.com/infocenter/iseries/v7r1m0/index.jsp?topic=%2Fddp%2Frbal1exitpgms.htm
> for a list of DRDA PRDID's.
