MATRIXX Configuration
- About MATRIXX Configuration
  MATRIXX Configuration describes the tasks required to configure MATRIXX components.
- Configuring MATRIXX Using Helm
  Configure MATRIXX by adding values for properties from the MATRIXX Helm chart in your Helm values file. The MATRIXX Helm chart includes component sub-charts in a hierarchy of reusable components.
- Configuring MATRIXX Engine
  MATRIXX Engine configuration can be applied from a configuration source.
- Configuring Traffic Routing Agent
  Traffic Routing Agent (TRA) configuration can be added to the deployment with a configuration source.
- Configuring Sub-Domain Routing (Multiple Sub-domains)
  In a MATRIXX environment where multiple customer sub-domains are implemented in separate engine chains, you configure sub-domain routing so that traffic is directed to the correct customer sub-domain where the subscriber is homed. You must configure different components across MATRIXX for sub-domain routing to work.
- Example Single Domain Deployments
  Example configurations are provided for single-engine, dual-engine, and dual-engine with Traffic Routing Agent in disaster recovery mode (TRA-DR) cloud native MATRIXX examples.
- Configuring MATRIXX Gateways and Web Apps
  In a non-containerized installation of MATRIXX, configure MATRIXX gateways and web apps using files in the /opt/mtx/conf directory in the pod(s) hosting those components. In a cloud native deployment, configuration files can be provided in the /opt/mtx/conf directory of the component container(s) using the following methods:
- Configuring CDR Processing
  The MATRIXX Engine can import and rate Solution42® call detail records (CDRs) and generate MATRIXX Event Detail Records (EDRs) from them. Generally, this is used only when integrating with an Oracle BRM system. Other projects should use external mediation to convert external CDRs into Diameter messages for MATRIXX processing.
