Consolidator - Configuring runtime

For your Consolidator to run, it must be defined as a process and included as a service definition. Make sure you update the following files in your application:

  • processes.xml
  • service-definitions.xml

Adding the Consolidator to processes.xml​

Your application's processes.xml file is located in the .cfg folder for the application. The file contains tags that define key characteristics of the Consolidator - for example, dependencies and logging level.

Here is an example configuration (the tags are explained in the page on the processes.xml file):

<process name="POSITION_CONSOLIDATOR">
        <groupId>POSITION</groupId>
        <description>Consolidates trades to calculate positions</description>
        <start>true</start>
        <options>-Xmx256m -DRedirectStreamsToLog=true -DXSD_VALIDATE=false -XX:MaxHeapFreeRatio=70 -XX:MinHeapFreeRatio=30 -XX:+UseG1GC -XX:+UseStringDeduplication -XX:OnOutOfMemoryError="handleOutOfMemoryError.sh %p"</options>
        <module>genesis-pal-consolidator</module>
        <package>global.genesis.pal.consolidator</package>
        <primaryOnly>true</primaryOnly>
        <script>position-consolidator.kts</script>
        <loggingLevel>DEBUG,DATADUMP_ON</loggingLevel>
        <language>pal</language>
    </process>
</process>
important

In a multi-node environment, Consolidator services should be set to primary only; otherwise, the changes will be applied multiple times.

Arguments tag​

In addition to the tags in the example, you can also add an <arguments></arguments> tag. This allows you to define process arguments that should be passed to the process on start-up.

Here you can pass the --coldStart argument which cold-starts the process. This avoids the danger of losing your calculated data.

For example:

<process name="POSITION_CONSOLIDATOR">
        <groupId>POSITION</groupId>
        <description>Consolidates trades to calculate positions</description>
        <start>true</start>
        <options>-Xmx256m -DRedirectStreamsToLog=true -DXSD_VALIDATE=false -XX:MaxHeapFreeRatio=70 -XX:MinHeapFreeRatio=30 -XX:+UseG1GC -XX:+UseStringDeduplication -XX:OnOutOfMemoryError="handleOutOfMemoryError.sh %p"</options>
        <module>genesis-pal-consolidator</module>
        <package>global.genesis.pal.consolidator</package>
        <primaryOnly>false</primaryOnly>
        <script>position-consolidator.kts</script>
        <loggingLevel>DEBUG,DATADUMP_ON</loggingLevel>
        <language>pal</language>
        <arguments>--coldStart</arguments>
    </process>
</process>

Adding the Consolidator to the service-definitions.xml​

Your application's service-definitions.xml file is where you specify the ports used by each process for communicating internally. You need to add an entry for your Consolidator, using an unused port number. For example:

 <service host="localhost" name="POSITION_CONSOLIDATOR" port="11003"/>
