HI! I can't tell what else should be needed on clustered env but: - on the (core) client you have to add minLargeMessageSize on your URL parameters eg tcp://localhost:61616?minLargeMessageSize=<put here the value you need> - on the server you have to change/add journal-buffer-size on broker.xml in order to be >= minLargeMessageSize
Probably i'm just paranoid but I will change the consumerWindowSize on the client to be >= minLargeMessageSize as well, but I could be wrong on that. -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
