June's Featured Webinar - CoreDX DDS Troubleshooting

View the webinar here

The power of the CoreDX DDS technology comes from its flexibility to adapt to incredibly complex and challenging environments. While using CoreDX DDS for basic communications is a trivial activity, using the more robust and powerful features in a large networked system can quickly become a complex activity. In these scenarios, it is critical to have proven techniques and tools that are straightforward and easy to use, and have the power to analyze, diagnose, and elegantly report the communications details of your system.

This webinar dives into the common techniques and tools used for analyzing, debugging, and troubleshooting DDS networks and applications.

Twin Oaks Computing has a library of recorded webinars, covering a variety of DDS technical concepts. You can browse the webinar library here.

CoreDX DDS Tips & Tricks

Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers.

Logging Flags

Enabling CoreDX DDS logging can be an effective tool for debugging CoreDX DDS applications. Logging flags can be enabled through the application API (logging QoS policy on DDS Entities), through QoS XML configuration, or through environment variables. No matter the method, individual logging flags will be enabled or disabled depending on the kind of logging messages desired.

The full list of available CoreDX DDS logging flags can be found in coredx_logging.h header file delivered with CoreDX DDS distributions. Here are some suggested flag combinations:

  • For general discovery debugging: DISCOVERY (0x02) + FACTORY (0x08) + LIVELINESS (0x10)
  • For data delivery debugging: DISCOVERY (0x02) + LIVLINESS (0x10) + HANDSHAKE (0x100)
  • For reader and/or writer cache debugging: DISCOVERY (0x02) + LIVLINESS (0x10) + HANDSHAKE (0x100) + CACHE (0x200)
  • For RPC debugging: DISCOVERY (0x02) + RPC_FACTORY (0x10000) + RPC_REQUEST (0x20000) + RPC_REPLY (0x40000)

For additional information, look at the Logging section of the CoreDX DDS Programmer's Guide.

CoreDX DDS Tips & Tricks are intended to be useful for engineers using CoreDX DDS. If you have any questions, please contact us.
