If you are using JBoss Fuse, you can try to camel master component[1], it
just starts the master component at the first place.

This means that the slave is connecting the IBM MQ even with the

Re: Master Slave Camel-ActiveMQ
Hi, You don’t need to let the Slave run when the Master is in charge. I think you can take a look at the camel-zookeeper[1]. The other two options for singleton clustering are: a) Master component [1] from Fuse Fabric [2] (if you deploy your application on Karaf/ServiceMix) b) JGroups component [3] Choose your weapon :) .

Re: Master Slave Camel-ActiveMQ
ActiveMQ or WebSphere MQ?

Hi
We are trying to setup Master slave for ActiveMQ using camel-context. Our
current architecture is like this.
1. A camel route which subscribes to MQ topics (these MQ topics are IBM

2. This camel route then takes the message from the topic and
transforms
it
3. The transformed message is saved in the database.
I have been trying to setup master slave but have not been successful so
far. This is what I'm doing
A.An instance of this application deployed on tomcat.
B.The slave is just another instance of this same application.Please note
that the clientids and the subscriber names are the same on both these
instances. Hence the slave would give the following exception , which is
expected.

We are using the default KahaDBPersistenceAdapter . The issue here is that
the slave container runs for few hours and just dies due to insufficient
java heap space.
I was trying to configure the kahadb adapter to not poll every 2-3 seconds
,
which it seems to be doing , but haven't been successful so far.
How do I configure the kahadb to poll during longer intervals (say 5
mins)?
Or are there any more options other than the kahadb for this Master Slave
setup?
