Hello, What about this question below ?

I don't know if you can specify the store size via the URL - I suspect not. You can provide an activemq.xml config file for ActiveMQ running in TomEE - high level instructions are here: https://tomee.apache.org/latest/docs/jms-resources-and-mdb-container.html - see the "Internal ActiveMQ Broker with activemq.xml" section. I second JB's comment though - people worry about the kahadb logs not getting removed and filling up the disk. Ensuring that all your messages are consumed or purged will ensure these files are cleaned up, rather than the store continually growing. One other note, running ActiveMQ embedded in TomEE will mean that resources are shared between the two. If you have large message volumes, it may be worth swapping to an standalone ActiveMQ broker, and pointing TomEE to that. Instructions for that are in the link above as well.
