Chapter 2. Editing a Broker's Configuration

Red Hat AMQ configuration uses a combination of an XML configuration template and OSGi PID configuration. This combination makes it possible to change specified broker properties on the fly. How you change the configuration depends on how the broker instance is deployed.

2.1. Introduction to Broker Configuration

Configuring a broker involves making changes to a number of properties that are stored in multiple locations including:
  • an XML configuration file
  • OSGi persistent identifier properties
How you make the changes depends on how the broker is deployed:
  • standalone—if a broker is deployed as a standalone entity and not a part of a fabric, you change the configuration using a combination of directly editing the broker's configuration template file and the console's config shell.
  • in a fabric—if a broker is deployed into a fabric its configuration is managed by the Fabric Agent which draws all of the configuration from the fabric's registry. To modify the container of a broker running as part of a fabric, you need to modify the profile(s) deployed into it. You can do this by using either the fabric:profile-edit console command or the management console.
Many of the configuration properties are managed by the OSGi Admin Service and are organized by persistent identifier or PID. The container services look in a specific PID for particular properties, so it is important to set the properties in the correct PID.
