By default, HornetQ server runs with 1GiB of memory. If your computer has less memory, or you want to run it with more available RAM, modify the value in bin/run.sh accordingly.

For persistence, HornetQ uses its own fast journal, which you can configure to use libaio (which is the default when running on Linux) or Java NIO. In order to use the libaio module on Linux, you'll need to install libaio, if it's not already installed.

If you're not running on Linux then you don't need to worry about this.

You can install libaio using the following steps as the root user:

Using yum, (e.g. on Fedora or Red Hat Enterprise Linux):

yum install libaio

Using aptitude, (e.g. on Ubuntu or Debian system):

apt-get install libaio

After downloading the distribution, unzip it into your chosen directory. At this point it should be possible to run straight out of the box, the following describes the directory structure:

         |___ bin
         |
         |___ config
         |      |___ jboss-as-4

HornetQ can also be deployed in JBoss AS 5. It is not currently shipped by default with the application server (it is scheduled to be shipped as default JMS provider in JBoss Application Server 6.0), so you will need to create new AS 5 profiles to run AS 5 with HornetQ.

To create AS 5 profiles:

This will create 2 new profiles in $JBOSS_HOME/server:

You can then start JBoss AS 5 using one of these profiles, e.g. :

$JBOSS_HOME/bin/run.sh -c default-with-hornetq

As in AS 4, it is not shipped by default with the application server, so you will need to create new AS 4 profiles to run AS 4 with HornetQ.

To create AS 4 profiles:

This will create 2 new profiles in $JBOSS_HOME/server:

You can then start JBoss AS 4 using one of these profiles:

$JBOSS_HOME/bin/run.sh -c default-with-hornetq
