Architecture Overview

The application debugging architecture has two components:

• XRAY Debugger for ChorusOS

• Remote debug server (RDBC) rdbc(1CC)

The XRAY Debugger for ChorusOS runs on the host. The remote debug server runs on the target and communicates with XRAY over the Ethernet. This is illustrated in Figure 10-1.

Figure 10-1 Application Debugging Architecture

Application debugging is intended to be used for debugging user applications, dynamically loaded actors, as well as certain supervisor actors. It is not possible to debug the Actor Management (AM) or I/O Management components (IOM), the kernel, or the system drivers. Application debugging relies on the RDBC supervisor actor which uses the services of the AM, the IOM, the kernel, and system drivers such as the Ethernet driver. When an application is debugged, only that application is affected. Other applications in the operating system, as well as the operating system itself, will keep running.
