Subject [jira] [Commented] (DERBY-5920) Network Server should accept DRDA connections from drivers with the StarQuest PRDID "SIG"
Date Mon, 17 Sep 2012 15:18:08 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5920?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13457076#comment-13457076
] 

Bryan Pendleton commented on DERBY-5920:
----------------------------------------

I'm +1 to supporting other network clients; I'd like to encourage open interoperability if
at all possible.

David, several questions:
1) Have you made a proposed patch to re-enable the support for your client?
2) Have you run the existing Derby regression tests with your client?
3) Is your client freely available? Or is it a licensed product? I guess I'm wondering
how other Derby developers would go about verifying that some future modification
or enhancement to the Derby client/server behaviors works correctly with your client.

I think it would be great if you could attach a proposed patch which shows the details
of re-enabling support for your client.

Regarding testing, the starting point for learning about the Derby regression test
suite is: (a) java/testing/README.htm in the trunk source, and (b) the Derby wiki
at http://wiki.apache.org/db-derby/DerbyJUnitTesting

>                 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.
