Subject [jira] [Commented] (DERBY-5920) Network Server should accept DRDA connections from drivers with the StarQuest PRDID "SIG"
Date Tue, 11 Sep 2012 20:36:07 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5920?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13453385#comment-13453385

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?

>             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.
