The JBoss A-MQ cartridge is shipped as an RPM package. You download the package from the JBoss A-MQ product page on the Customer Portal and install the cartridge with yum in the same way you install other OpenShift Enterprise components.
What's different in the JBoss A-MQ cartridge

When you create and run JBoss A-MQ applications in the OpenShift Enterprise domain, note the following differences between the cartridge and the standalone JBoss A-MQ product:
- Fabric management
- Each JBoss A-MQ application that you create is deployed with fabric by default.
- Some fabric profiles, such as Gateway and Tomcat, are not supported.
- You cannot create child containers. Each container that you deploy acts as a standalone application in the domain.
- The first application that you create includes the ZooKeeper instance with the user credentials and environment variables that subsequent applications require to run.
- Secured shared file systems are not supported.
- Ports and networking
- You can use only 3 private application ports to connect to the JBoss A-MQ applications. The ports are defined in system properties.
- The PublicPortMapper tool maps the private application ports to public ports before external clients can connect to the JBoss A-MQ applications.
- UDP connections are not supported.
- High availability
- The first JBoss A-MQ application in the OpenShift Enterprise domain acts as the master node in the cluster.
- You must install a standalone JBoss A-MQ instance and configure the ZooKeeper ensemble outside of the OpenShift Enterprise domain to manage applications inside the domain.
- You must configure the cluster to use JDBC Master Slave or Replicated LevelDB Store.
- Auto-scaling is not supported.
