OpenDDS is an open-source C++ implementation of the Object Management Group's specification "Data Distribution Service for Real-time Systems". Although OpenDDS is itself developed in C++, Java and JMS bindings are provided so that Java applications can use OpenDDS. OpenDDS also includes support for the DDS Security specification.

OpenDDS is built on the ACE abstraction layer to provide platform portability. OpenDDS also leverages capabilities of TAO, such as its IDL compiler and as the basis of the OpenDDS DCPS Information Repository (DCPSInfoRepo).

The primary development of OpenDDS was done by Object Computing, Incorporated in St. Louis and Phoenix. It is released under the same generous license terms as ACE, TAO and MPC. See the LICENSE file for details.

The OpenDDS Developer's Guide is freely downloadable at: http://download.objectcomputing.com/OpenDDS/

The TAO Developer's Guide book set may also be purchased from: http://www.theaceorb.com/purchase/index.html

If you encounter any problems with this release please fill out the PROBLEM-REPORT-FORM file found in this directory and use it when posting to the mailing list or creating a GitHub Issue.

For commercial support please see http://opendds.org/support.html.

This release of OpenDDS is based on the DDS Specification formal/2015-04-10 (version 1.4). It features the following transport protocols:

• TCP/IP
• UDP/IP
• IP multicast
• RTPS over UDP/IP (unicast and multicast)

RTPS (Interoperability) features are based on the DDS-RTPS Specification formal/2014-09-01 (version 2.2). See the OpenDDS Developer's Guide and the file docs/design/RTPS for more details on RTPS.

See the Developer's Guide for information on OpenDDS compliance with the DDS specification. If you would like to contribute a feature or sponsor the developers to add a feature please see the Support section above for contact information.

OpenDDS requires TAO for both IDL compilation as well as interaction with the DCPSInfoRepo. If you will be using the "configure" script for OpenDDS (see the INSTALL file for details), you do not need to download TAO first -- the "configure" script will download it for you.

Use one of the following versions when building OpenDDS:

• TAO 2.2a patch 15
• TAO 2.5.1 (DOC Group)

Note that the 2.2a release is from OCI and can be obtained from http://www.theaceorb.com/. The DOC Group releases can be obtained from http://download.dre.vanderbilt.edu/.

GNU Make 3.80+ was used for automating the compiling and linking of OpenDDS on Unix and Linux systems.

Perl is used for running the automated tests and examples included in this source tree and generating Makefiles or Visual Studio project files. On Windows we recommend the use of ActiveState Perl. The configure script also uses Perl.

For building and installation instructions see the INSTALL file in this directory.

Docker images containing a pre-built OpenDDS are available on DockerHub. An image corresponding to a particular release has a tag of the form release-DDS-X.xx, e.g., release-DDS-3.12.

1. Check for prerequisites

    docker --version
    docker-compose --version
   

2. Enter a container

    docker run --rm -ti -v "$PWD:/opt/workspace" objectcomputing/opendds
   

3. Copy the Messenger directory which contains an example from the Developer's Guide

    cp -R /opt/OpenDDS/DevGuideExamples/DCPS/Messenger Messenger
    cd Messenger
   

4. Configure and build the Messenger example

    mwc.pl -type gnuace
    make
   

5. Exit the container

    exit
   

6. Enter the Messenger directory

    cd Messenger
   

7. Create an rtps.ini file to control discovery with the following content

    [common]
    DCPSGlobalTransportConfig=$file
    DCPSDefaultDiscovery=DEFAULT_RTPS
   
    [transport/the_rtps_transport]
    transport_type=rtps_udp
   

8. Run the Messenger example with RTPS

    docker-compose up
   

9. Run the Messenger example with InfoRepo

    docker-compose -f docker-compose-inforepo.yml up
    # Use Control-C to kill the InfoRepo process
