Subject Re: ActiveMQ Dynamic Configuration at Runtime

To answer your question, if you want to configure the memory usage in the
broker, it can be re-read but only at broker start time.
The log4jproperties *can *be re-read on-the-fly (without broker restart),
but not the system-usage etc. configuration.

But there is a hard jvm limit that you have to work within anyway.
Once you start the jvm, the -Xmx (for hotspot) value for maximum heap space
is set for the life of that vm. Everything that will be on the heap has to
come out of that budget (I mean you could only adjust within the -Xmx total
in any case.)
