> Key: DERBY-4646
> URL: https://issues.apache.org/jira/browse/DERBY-4646
> Project: Derby
> Issue Type: Improvement
> Components: Store
> Affects Versions: 10.0.2.0, 10.0.2.1, 10.1.1.0, 10.1.2.1, 10.1.3.1,
> 10.2.1.6, 10.2.2.0, 10.3.1.4, 10.3.2.1, 10.3.3.0, 10.4.1.3, 10.4.2.0,

> Environment: Linux; Sun CVM phoneme_advanced_mr2
> Reporter: Dag H. Wanvik
>
> The small device platform we support based on CDC/Foundation 1.1 does not
> support the NIO based method used by Derby to guarantee against dual boots of
> a database by different VMs. It would be nice to have a way to guarantee
> against this scenario.
> Currently, one would have to use the property
> derby.database.forceDatabaseLock with the ensuing hassle of cleaning away
> orphaned lock files.
> The default behavior is "false", so then all Derby does if to print a warning
> to derby.log and System.err.
> Cf discussion in
> https://issues.apache.org/jira/browse/DERBY-4179?focusedCommentId=12864945&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12864945
> Apparently this is not an issue on the Windows platform.
