Installation of Apache ActiveMQ Artemis
The first step in the installation of the message service is to download and extract the ActiveMQ Artemis distribution. The software can be downloaded from https://activemq.apache.org/artemis/download.html and we currently recommend version 2.9.0. You can extract the contents of the downloaded archive anywhere you have space in your filesystem but we recommend that you keep the distribution of the Artemis software separate from the directory where you have OpenEMPI installed. This will allow you to upgrade to future version of OpenEMPI and Artemis software independently of the instance of OpenEMPI you are maintaining.
The next step is to create an instance of the messaging server or broker. In the following example we assume that the environment variable ARTEMIS_HOME points to the directory where you extracted the contents of the ActiveMQ Artemis software and OPENEMPI_HOME points to the directory where you have OpenEMPI installed.
$ ${ARTEMIS_HOME}/bin/artemis create ${OPENEMPI_HOME}/artemis --user openempi \
--password openempi --require-login
Creating ActiveMQ Artemis instance at: /sysnet/openempi/artemis
Auto tuning journal ...
done! Your system can make 0.53 writes per millisecond, your journal-buffer-timeout will be 1900000
You can now start the broker by executing:
"/sysnet/openempi/artemis/bin/artemis" run
Or you can run the broker in the background using:
"/sysnet/openempi/artemis/bin/artemis-service" start
Once the broker has been created, you can start it using the commands shown above by the broker after it starts.
$ /sysnet/projects/3.5.x/openempi/artemis/bin/artemis run

You now need to configure OpenEMPI to specify how it should connect to the broker during startup. The configuration requires three parameters:
- The URL that OpenEMPI should use to connect to the running broker (using the parameter brokerUrl).
- The username that OpenEMPI should use to connect to the broker (using the parameter brokerUsername).
- The password that OpenEMPI should use to connect to the broker (using the parameter brokerPassword).
All three parameters are specified in the applicationContext-resources.xml file as shown below. The brokerUsername and brokerPassword must match the values used during the creation of the broker above. The listening hostname, port number and many other configuration parameters for the broken can be specified in the broker.xml file that was created in the etc directory of the broker instance you created above.
