Subject [jira] [Commented] (AMQ-4882) LevelDB can get to a corrupt state when using XA transactions
Date Wed, 12 Mar 2014 16:03:44 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13931906#comment-13931906

Chris Geer commented on AMQ-4882:
---------------------------------

Does LevelDB support XA Transactions? I've seen a few references that says it doesn't. i.e.
https://access.redhat.com/site/documentation/en-US/JBoss_A-MQ/6.0/html/Configuring_Broker_Persistence/files/LevelDBConfiguration.html

> A consumer/producer with failover transport is connected to AMQ and processes messages
in XA Transactions. When AMQ is restarted is can happen that LevelDB gets to a corrupt state
so that AMQ can not be started anymore without deletind the database.
> Reproduction:
> - Configure AMQ with LevelDB
> - Run the attached TestClient
> - Restart AMQ several times. At some time it won't start anymore and produced the exception
in the attached log file.
