---------------------------------
if kahadb could implement the scheduler store interface we would be in business
> Recover scheduler database option

> The problem is that there is no way to restore the database like you can if
> you are working with the main ActiveMQ database. You can fix the main
> database by specifying the following configuration:
> {code}
> <persistenceAdapter>
> <kahaDB directory="${activemq.base}/data/kahadb"
> ignoreMissingJournalfiles="true"
> checkForCorruptJournalFiles="true"
> checksumJournalFiles="true" />
> </persistenceAdapter>
> {code}
> It would be nice to have the same feature for the scheduler database.
