RE: How can i reduce openjms.db files size

OpenJMS won't store NON_PERSISTENT messages in the database.
It will store administered destinations (any destination listed in
openjms.xml,
or created via the admin API) and durable topic subscribers.
 
 
 From: qiang zhou



Hello:
 
   My JMS send message code as this:
     TopicSession session = connection.createTopicSession(
                    false, Session.AUTO_ACKNOWLEDGE);
     topic = (Topic)context.lookup(topicName);
    TopicPublisher publisher = session.createPublisher(topic);
     publisher.publish(topic,message,DeliveryMode.NON_PERSISTENT,3,1000);
   
   openJMS  need write this message in its DB? or only contain in memory
cache. When the message is overtiem ,then delete for ever.
   If i setting the timeToLive ==0, openJMS would store it forever?
 
 
Thanks !!

No idea. I don't use openjms.db and don't recommend anyone 
else does either. Support for it has been dropped in 0.7.7.

In 0.7.7, the database shipped with OpenJMS is slated to be
Derby. You could replace your JDBM database with Derby, or
HSQLDB.
