Hi all,
Im trying to optimize and hardening activemq and I have some question:
- If I set producerFlowControl to false, should I need to set the memory
limit? I dont know if I set the memory limit, firstly all messages goes to
memory until is full, and after that goes to disk?
- Do I need to set
Abimael,
Just to follow up on what Matt said, the messages in the log files will only
be deleted once they're *all* consumed. If you have a log file where all but
one message is consumed, the log file will stay around until the last
message is consumed.
Thanks,
Christian

The error appears to be that the ActiveMQ connection was closed. If you
are using connection pools, you might look into your configuration there
and see if you set some timeouts. Its been a while since 4.x, so I
can't remember off the top of my head how the default behavior works.
Glad to hear. Yes, the "store" limits the disk space that the broker
will use. Once that limit is reached, the broker will kick in "producer
flow control", where it will not ack messages to producers. This allows
the consumer to "catch up" and drain the queues.
You shouldn't have to tweak t

Does anyone know if this issue with BROKER_NAME in ACTIVEMQ_LOCK table has
ever been resolved?
It seems that for some reason it was decided that broker cluster (i.e. group
of 1 master and N slaves) must have a dedicated database instance?! Using

Thank you.
Yes, while I was waiting for the response, I did a test with more than
50 messages with the Consumer application STOPPED.
I noticed that there was db-XX.log files (several of them) . Once I started

What method of the cms::MapMessage do I use to extract the values from a
ActiveMQ.Statistics.Broker query? I'm getting a reply and I can output a
list of map names but no values!
Using this code :
const cms::MapMessage * map = dynamic_cast < const cms::MapMessage *
>(message) ;
const std::vector
persistence is an attribute of each message, how are you sending the messages?
And you need to be sending to a queue or use durable subscriptions on a topic.
have a go with the examples, ant consumer, and producer to get started.

Hey everyone,
I am currently developing a message-driven client-server-application that
involves sending around large files (1gb each). As I can not rely on
external transfer-services I am resorting to JMS Streams. After receiving a
certain amount of data the broker slows down and seems to have pr
