What is omniORB ?

omniORB is a robust, high-performance CORBA 2 ORB, developed by us. It is one of only three ORBs to be awarded the Open Group's Open Brand for CORBA. This means that omniORB has been tested and certified CORBA 2.1 compliant. You can find out more about the branding program at the Open Group.

We have decided to make omniORB freely available. Here's why.

omniORB implements the specification 2.3 of the Common Object Request Broker Architecture (CORBA). It is our third generation ORB (hence the name 'omniORB three'). The initial goal was to produce a standard conforming ORB that can deliver the performance required by the applications developed in-house. It has been deployed for lab-wide use since Mar 1997. In May 1997, the ORB was released externally as free software under the GNU Public Licences. The latest release - 3.0.4- is the 11th public release of the software.

See a summary of technical details of omniORB. It supports the C++ language binding; is fully multithreaded; uses IIOP as the native transport; and comes complete with a COS Naming Service.

There are some performance measurements. It's pretty quick, possibly the fastest CORBA 2 compliant ORB around.
