[jboss-user] [JBoss Messaging] - Re: question about DownCacheSize

[jasonhu919]

I was talking about database persistent messages.

when DownCacheSize=10000,  client puts 5000 messages in the queue, the client finishes sending, then I check right away, queue size from jmx console shows 5000, but database jbm_msg table shows size still 2000,  but it is increasing, so if I restart the jboss now, will all the messages which have not been paged to database get lost? if not, how does it handle it? backed up by disk file?
