Thanks a lot Christian this does look like a viable solution. I think 'Using
Filtered destination' is the key here. I want to confirm one thing here that
is if we publish messages with multiple filters to the topic say "odd =
'yes'" and "i = 5" but we'll only have one filteredDestination as below
It is one of the better options, otherwise you are stuck with an RDMBS
or a clustering filesystem.
LevelDB in very new development offer some new cool stuff.

This option is definitely doable, but not the best solution. Is there any
other way to set up two stand-alone PC-s with AMQ, a master and slave ?

Yep, you can do so with a shared disk so that master and slave look at the
same persistent store. When master goes down, slave can take over right
where master left off.
Take a look here for details:

check out virtual topics wiki and the section on filtered composite
destinations:

Sound to me like you want a database and not ActiveMq.
Producer inserts a record and deletes all previous (in that order in 1
transaction with rollback to assure that clients can always retrieve a
record).
Use a date/time for the key.
Clients retrieve the last key in the table.

Hi!
Is it possible to set up AMQ failover master-slave solution so, that master
is in one PC and slave is on other PC? So if something happens with the PC
where master is running, secondary is not affected and can take over.
If yes, how should I configure?
Thanks in advance.

Is there a way to bind the queues with Topics based on a property in message
header to filter the messages I need to get.
For example:
1. I have two topics named request and response.
2. I'm getting messages to topic request with a header property with
destinations as X and Y
3. I need to bind re

on your clients, enable trace level logging for :

that will help you see what is going on under the hood till the

There could be some dns/ip matching issues between the client and the brokers.

You are right, the problem is caused by the client.
The expiry timeout for the PooledConnectionFactory was set to 1ms by
default,
so every connection was going to TIME_WAIT state after 1ms if not used.
I have increased this numer and now I have a nice low number of TIME_WAIT
connections.
thanks

Hi,
I am new to ActiveMQ. Reading documentation and playing with examples. But
there is a key scenario I need to implement, but not sure if ActiveMQ can
support it, and, if it does, how.
- Client publishes topic to broker
- Only most recent message on topic is needed
- Messages can be very large
13 matches
