This is version 3.0.4 of omniORB. We also refer to this version as omniORB3. This release is a minor release since omniORB 3.0.3. For a summary of changes since the last release, please read the file ReleaseNote_omniORB_304.
omniORB3 is copyright AT&T Laboratories - Cambridge. It is free software. The programs in omniORB3 are distributed under the GNU General Public Licence as published by the Free Software Foundation. See the file COPYING for copying permission of these programs. The libraries in omniORB3 are distributed under the GNU Library General Public Licence.

We impose no restriction on the use of the IDL compiler output. The stub code produced by the IDL compiler is not considered a derived work of it.
README files
IMPORTANT NOTE for users upgrading from 2.7.1 or earlier:Since 2.8.0, omniORB2 has been updated to CORBA 2.3. In order to comply with the 2.3 specification, it is necessary to change the semantics of the extraction of string, object reference and typecode from an Any. Please read CHANGES_280 for details.
Technical Highlights
omniORB3 is an Object Request Broker (ORB) which implements specification 2.3 of the Common Object Request Broker Architecture (CORBA).
- C++ language bindings are supported. The mapping conforms to the latest revision of the CORBA specification.
- Support for the Portable Object Adapter (POA) NEW!
- Support for the Interoperable Naming Service (INS)NEW!
- The Internet Inter-ORB Protocol (IIOP 1.0) is used as the native protocol.
- The omniORB3 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)
- The Dynamic Invocation and Dynamic Skeleton interfaces are supported
- 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.x (x86)/egcs-1.1.2/binutils-2.9.1.0.14/GNU Libc version 2
- HPUX 11.00/ aC++
- SGI Irix 6.x/SGI C++ compiler 7.2
Ports to the following platforms are available. These ports are done by external contributors and have been integrated into the source tree. For these platforms, no pre-compiled binary is available.
- Digital Unix 4.0D/ DEC C++ compiler version 6.1
- IBM AIX 4.2/ IBM C Set++ 3.1.4
- IBM AIX 4.3/ IBM C Set++ 3.6.6
- HPUX 10.20/ aC++ (B3910 A.01.04)
- OpenVMS Alpha 6.2/ DEC C++ compiler 6.2/5.5 (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++
- Phar Lap's Real Time ETS Kernel
- SCO Unixware 7
- Linux 2.x powerpc/Debian
- An earlier port to MacOS exists but has not been fully integrated into the source tree. An adaption kit is available here.
- An earlier port to the embedded OS RTEMS exists. More information is available here.
- Linux 2.0 (x86)/ GNU C++ compiler version 2.7.2 /libc-5/ Linuxthreads 0.5
- SCO OpenServer 5/g++ (May need some changes in the source to work around compiler bugs. The compiler can compile omniORB 2.7.1 unchanged.)
- Digital Unix 3.2/ DEC C++ compiler version 5.5 (Need to apply the patch in patches/dec_CXX_5.6.patch to work around compiler bugs.)
A ports to LynxOS is known to exist but it has not been integrated into the source tree.
It should be straightforward to port omniORB3 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
omniORB3 is not yet a complete implementation of the CORBA core. The following features are not supported in the current release.
- Support for IDL type longlong, longdouble, wchar, wstring, fixed, valuetype
Missing features
The following features are missing from omniORB3. We are not currently planning on adding support for these features.
- omniORB3 does not has its own Interface Repository. However any CORBA compliant Interface Repository can be used with omniORB3.
Installation
Installation instructions are provided in the following files:
Documentation
- omniORB3 user guides are located in the ./doc directory. They are available in latex, postscript, acrobat and html formats.
- 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 omniORB3 are located in ./src/examples.
Recommended Additional Documentation
omniORB3 is based on the following OMG specifications.
- The Common Object Request Broker: Architecture and Specification. The current version can be found on the OMG website, here. In particular, omniORB3 users will find chapter 3 "OMG IDL Syntax and Semantics" and chapter 23 "Mapping of OMG IDL to C++" particularly relevant.
- The COS Naming Service Specification. The current version is available on-line at the OMG website.
