Recover scheduler database option
---------------------------------
Key: AMQ-3758
URL: https://issues.apache.org/jira/browse/AMQ-3758
Project: ActiveMQ
Issue Type: Improvement
Components: Message Store
Affects Versions: 5.5.0
Reporter: Sergei Sokolov
I am not sure why, but Scheduler database got corrupted, and some messages
couldn't be delivered to a broker. I got many exceptions similar to:
{code}
2012-03-02 03:26:08,234 | ERROR | JMS Failed to schedule job |
org.apache.activemq.broker.scheduler.JobSchedulerImpl | JobScheduler:JMS
java.io.IOException: Could not locate data file <correct-file-path>\db-2.log

{code}
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.
