Knut Anders Hatlen commented on DERBY-5920:
-------------------------------------------
I don't think we maintain a list of protocol extensions. However, in the cases
where we've extended the protocol, the server should already be checking that
it talks to a client that understands the extension. That is, it checks that
the PRDID is DNC and that the client version is recent enough to support the
extension. So it should not use the extensions when talking to a non-DNC
client. The supports* methods in org.apache.derby.impl.drda.AppRequester would
be a good starting point for exploring which extensions exist.
> Network Server should accept DRDA connections from drivers with the StarQuest
> 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.
