Greetings! I want unexpired JMS messages to be redelivered if my client application is stopped and restarted. To accomplish this, I do not have the client acknowledge the receipt of messages. An unfortunate side-effect of this practice is that the db-/N/.log files in the ${activemq.data}/kahadb directory never get cleaned up, and after these build up to a few hundred in number, ActiveMQ starts affecting the performance of it clients (although I cannot yet tell if it is the producer part that's bogging down or the consumer part that's bogging down). I did add to activemq.xml, but commented out and don't remember why, but this did cause some sort of problem when I last tried it over a year ago...
As I see it, there are three ways to get around this problem. I don't know if any of them are possible, and is what I am seeking advice about. They are: 1) figure out a way to have unexpired messages redelivered even if they've been acknowledged. 2) figure out a way to have the delivered (but expired) messages purged even though they haven't been acknowledged by the client. (Currently, if they are not acknowledged, they are marked "in-use" and the db-/N/.log files aren't cleaned up.) 3) occasionally delete the older db-/N/.log outside of ActiveMQ (say on cron, etc.), but will this cause ActiveMQ to behave improperly? Or is there a different way altogether?
