Subject journaled JDBC - migrating from 5.1.0 -> 5.4.1
Date Tue, 05 Oct 2010 02:36:32 GMT

It looks like JDBC journaling configuration has changed between 5.1.0 and
5.4.1.  As per the 5.4.1 xml schema
(http://activemq.apache.org/schema/core/activemq-core-5.4.1.xsd) the only
likely options appear to be:

<persistenceFactory>
 <journaledJDBC/>
</persistenceFactory>

and,

<peristenceFactory>
  <journalPersistenceAdapterFactory/>
<persistenceFactory>

==journaledJDBC==
I attempted to get the first form working because it closely approximated
our existing amq 5.1.0 config and because it matched FUSE
documentation(http://fusesource.com/docs/broker/5.4/persistence/FuseMBPersistJDBCJournaled.html):

        <persistenceFactory>
            <journaledJDBC
dataDirectory="${activemq.base}/data-journaledJDBC"
dataSource="#oracle-ds"/>
        </persistenceFactory>

Unfortunately that config results in an IllegalStateException.  Cannot
convert value of type
[org.apache.activemq.store.journal.JournalPersistenceAdapter] to required
type [org.apache.activemq.store.PersistenceAdapterFactory] for property
'persistenceFactory': no matching editors or conversion strategy found

==journalPersistenceAdapterFactory==

        <persistenceFactory>
            <journalPersistenceAdapterFactory
dataDirectory="${activemq.base}/d\
ata-journaled" dataSource="#oracle-ds"/>
        </persistenceFactory>

This config seems to work.  AMQ starts up and I see activity in the dir
specified by dataDirectory.

==QUESTIONS==
- What is the difference between using journaledJDBC and
journalPersistenceAdapterFactory?
- If journaledJDBC is preferred, are there any suggestions on how to resolve
the IllegalStateException?

Carlos
