XML Configuration File

The configuration file uses XML format. Let's look at a very basic configuration file, just to get an idea of its contents. You will learn the meaning of each line as you read the rest of this section:

• QoS Configuration
• Configuring the Persistence Service Application
• Configuring Remote Administration
• Configuring Persistent Storage
• Configuring Participants
• Creating Persistence Groups
• Enabling Distributed Logger in RTI Services
• Enabling RTI Monitoring Library in Persistence Service

Example Configuration File
