Technical Highlights

omniORB2 is an Object Request Broker (ORB) which implements specification 2.0 of the Common Object Request Broker Architecture (CORBA).

  • C++ language bindings are supported. The mapping conforms to the latest revision of the CORBA specification.
  • The Internet Inter-ORB Protocol (IIOP) is used as the native protocol.
  • The omniORB2 runtime is fully multithreaded. It uses native platform thread support encapsulated with a small class library, omnithread, to abstract away from differences in native thread APIs.
  • TypeCode and type Any are supported.
  • DynAny is supported (CORBA 2.2)
  • A COS Naming Service, omniNames, is provided.
  • The following platforms are supported:
    • Solaris 2.{5,6}/ Sun SparcCompiler C++ version 4.2
    • Windows NT / Windows 95 / Visual C++ version 5.0 (and also version 6.0)
    • Linux 2.0 (x86)/ GNU C++ compiler version 2.7.2 /libc-5/Linuxthreads 0.5
    • Linux 2.0 (x86)/egcs-1.1b/binutils-2.9.1.0.14/GNU Libc version 2
    • Digital Unix 3.2/ DEC C++ compiler version 5.5
    • Digital Unix 4.0D/ DEC C++ compiler version 6.0

    Ports to the following platforms are available. These ports are done by external contributors and have been inte grated into the source tree. For these platforms, no pre-compiled binary is available.

    • IBM AIX 4.2/ IBM C Set++ 3.1.4
    • HPUX 10.20/ aC++ (B3910 A.01.04)
    • OpenVMS Alpha 6.2/ DEC C++ compiler 5.5 (UCX 4.1 ECO 8)
    • OpenVMS Vax 6.1/ DEC C++ compiler 5.5 (UCX 4.0 ECO 1)
    • NextStep 3.3/ gcc-2.7.2
    • Reliant Unix 5.43/CDS++
    • SCO OpenServer 5/g++
    • Phar Lap's Real Time ETS Kernel
    • SGI Irix 6.x/SGI C++ compiler 7.2

    Ports to LynOS and Mac OS are known to exist but they have not been integrated into the source tree.

    It should be straightforward to port omniORB2 to any platform which supports POSIX style threads, BSD style sockets and has a decent C++ compiler which supports exceptions.

  • It has been tested for interoperability via IIOP with other ORBs, such as Iona Orbix 2.2 MT, Iona OrbixWeb 2.0.1, Visigenic Visibroker for C++, and HP ORB Plus 2.5.

Work in progress

omniORB2 is not yet a complete implementation of the CORBA core. The following features are not supported in the current release.

  • The Dynamic Invocation Interface (DII) is not supported. Work is in progress.
  • The Dynamic Skeleton Interface (DSI) is not supported. Work is in progress.

Missing features

The following features are missing from omniORB2. We are not currently planning on adding support for these features.

  • The BOA only supports the persistent server activation policy. Other dynamic activation and deactivation polices are not supported.
  • omniORB2 does not has its own Interface Repository.

Installation

Installation instructions are provided in the following files:

  • README.unix for all unix platforms
  • README.win32 for Windows NT and Windows 95

Documentation

  • omniORB2 user guides are located in the ./doc directory. They are available in latex, postscript, acrobat and html formats. Latest versions are available here .
  • Man pages for the programs in this distribution are located in ./man directory.
  • README files are provided throughout the distribution tree. They provide specific information about the directories and files, tools and examples. You may want to explore the tree to become familiar with the information provided in the README files.

Examples

  • Example programs that demonstrate the use of omniORB2 are located in ./src/examples.

Recommended Additional Documentation

omniORB2 is based on the following OMG specifications.

  • The Common Object Request Broker: Architecture and Specification. The current version is available on-line at http://www.omg.org/corba/corbiiop.htm. In particular, omniORB2 users will find chapter 3 "OMG IDL Syntax and Semantics" and chapter 16 "Mapping of OMG IDL to C++" particularly relevant.
  • The COS Naming Service Specification. The current version is available on-line at http://www.omg.org/corba/sectrans.htm
