Subject [jira] [Commented] (DERBY-6669) Transactional integrity not maintained properly in multi-threaded system
Date Thu, 17 Jul 2014 11:51:04 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6669?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14064846#comment-14064846

Karl Wright commented on DERBY-6669:

Also: this test works properly on the other three databases MCF supports: PostgreSQL, MySQL,
and HSQLDB, so I have some confidence that it's not just a minor coding issue.

>                 Key: DERBY-6669
>                 URL: https://issues.apache.org/jira/browse/DERBY-6669
>             Project: Derby
>          Issue Type: Bug
>    Affects Versions:,
>         Environment: Windows; not clear if the same failure will occur on Linux or not,
timing seems to be critically important.
>            Reporter: Karl Wright
> The Apache ManifoldCF project uses Derby for testing and small deployments.  We're seeing
a situation where transactional integrity is compromised.  This is while using MVCC mode.
 Please refer to CONNECTORS-998 for complete details, as well as a test case you can run to
reproduce the problem.
> I am happy to run the failing example on the same hardware I used to generate the log,
if that would be helpful.
