completely disabling Kaha Store
I am embedding an ActiveMQ broker directly inside an app (long story). I am
doing so explicitly with Java code (i.e., "broker = new BrokerService();",
etc.). I would like to completely avoid any writing of files when
performing normal JMS tasks, such as sending and receiving messages (again,
long story... access control issues). [This may change later, but for now,
I am trying to avoid disk use. Persistence is not a concern.] I do this to
create/start the broker:
m_broker = new BrokerService();
m_broker.setBrokerName(S_STR_BROKER_NAME);
m_broker.addConnector("vm://" + S_STR_BROKER_NAME);
m_broker.setUseJmx(false);
m_broker.setPersistent(false);
m_broker.setPersistenceAdapter(null);
m_broker.start();
However, when I start the broker, I see the following log output:
INFO [main]: ActiveMQ 5.0.0 JMS Message Broker (mainbroker) is starting
INFO [main]: For help or more information please see:
http://activemq.apache.org/
INFO [main]: AMQStore starting using directory: activemq-data/mainbroker
INFO [main]: Kaha Store using data directory
activemq-data/mainbroker/kr-store/state
INFO [main]: Active data files: []

INFO [main]: Kaha Store successfully deleted data directory
activemq-data/mainbroker/kr-store/data

INFO [main]: ActiveMQ JMS Message Broker (mainbroker,
ID:yurik2.engr.akamai.com-54085-1207691353487-0:0) started
So, on the one hand, it is using MemoryPersistenceAdapter (as I want, I
think), but also it's initializing some Kaha stuff (and also Journal
stuff... not sure if that's separate or the same thing) -- which I'd rather
it not do, if possible.
Later, when the in-VM client (which, unlike the above broker initialization
code, is constrained by rather strict security rules about file writing)
does a JMS send(), I get a security exception:

It's trying to read "activemq-data/mainbroker/kr-store/data", which is not
allowed for reasons I won't go into here. Why is it trying to do this Kaha
stuff, if I want memory persistence only? Is there a way to disable this?
Thank you so much.

Unfortunately you need to set any persistence parameters before adding
a connector ...

Re: completely disabling Kaha Store
Posted by yg_cvg <yu...@ugcs.caltech.edu>.
Oddly enough, doing
m_broker = BrokerFactory.createBroker("broker:()?persistent=false");
instead of the first line below fixed the problem. Also, a bunch of
warnings about JMX (which I also explicitly tried to disable before) went
away. I'm not really sure why it fixed it, but it did. Based on the logging
before the fix, it looked like it was trying to do some Kaha stuff BEFORE
the setPersistent(false) line executes, so maybe that enables certain Kaha
stuff to keep happening even after that line, though I'm still not sure why.
Any insight would still be appreciated, but the above seems to fix the
problem.
