There currently isn't any tools to help you migrate between stores - but something we do intend to do (at some point). If you have only queue messages - start a new broker using KahaDB, with a oneway network connection to the old broker, with a static filter for all queues - and it will drain all the messages from it, and store them in KahaDB

Hi

I have a small project about activeMQ.

previously , I was used jdbcPersistenceAdapter for store message. But later,
it being more slower when starting and running. I checked my oracle
database, There was about 10,000 rows data in the activemq_msgs table. That
was not largely ,isn't it ?

now,I want to change the PersistenceAdapter's configration, from
jdbcPersistenceAdapter to kahaPersistenceAdapter. But there's only one question is how to keep the message datas which are stored in the oracle database? Is there a configration could change these datas to Kaha files ?

wish your answers
Thanks!
