Configuration Reference
This section is a quick index for looking up configuration. Click on the element name to go to the specific chapter.
Server Configuration
broker.xml
This is the main core server configuration file which contains the 'core' element. The 'core' element contains the main server configuration.
System properties
It is possible to use System properties to replace some of the configuration properties. If you define a System property starting with "brokerconfig." that will be passed along to Bean Utils and the configuration would be replaced.
To define global-max-size=1000000 using a system property you would have to define this property, for example through java arguments:
java -Dbrokerconfig.globalMaxSize=1000000
You can also change the prefix through the broker.xml by setting:
<system-property-prefix>yourprefix</system-property-prefix>
This is to help you customize artemis on embedded systems.
Modularising config into separate files.
XML XInclude support is provided in the configuration as such if you wish to break your configuration out into separate files you can.
To do this ensure the following is defined at the root configuration element.
xmlns:xi="http://www.w3.org/2001/XInclude"
You can now define include tag's where you want to bring in xml configuration from another file:
<xi:include href="my-address-settings.xml"/>
You should ensure xml elements in separated files should be namespaced correctly for example if address-settings element was separated, it should have the element namespace defined:
<address-settings xmlns="urn:activemq:core">
An example can of this feature can be seen in the test suites:
./artemis-server/src/test/resources/ConfigurationTest-xinclude-config.xml
N.B. if you use xmllint to validate xml's against schema you should enable xinclude flag when running.
--xinclude
For further information on XInclude see:
https://www.w3.org/TR/xinclude/
The core configuration
This describes the root of the XML configuration. You will see here also multiple sub-types listed. For example on the main config you will have bridges and at the list of bridge type we will describe the properties for that configuration.
