NvdmAPI is a Java-based object-oriented application programming interface (API) to HP OpenView Radia Configuration Servers (RCS, formerly known as Novadigm Radia Configuration Server). The interface provides full read / write access to the RCS database with easy-to-use object abstractions. In this respect it is a faster running and more intuitive to use replacement for HP's (Novadigm's) proprietary Tcl-based API. The NvdmAPI requires a Java VM 1.2 or above, and runs cross-plattform on Windows, Unix, Linux, MacOS, and so on.

As there have been quite some discussions between Novadigm and myself about potential infringements of copyrights or nondisclosure agreements, I want to clearly state the following:

This API has been implemented without any insight knowledge of the implementation of the Radia products, their internal protocol, or any other information not publicly available. When I developed the API, I did not work for Novadigm, nor did I have access to any internal Novadigm or HP material that would have facilitated my attempts. The sole input to this effort has been the TCP traffic logging of the RCS, which is a standard product feature and can be configured easily by everybody with simply setting a (well documented!) switch in the RCS configuration file. This logging allows to monitor the TCP traffic between the Radia System Explorer and the RCS on byte level.

NvdmAPI represents just my conclusions I've drawn from observing communications with the RCS. And while the API seems to work correctly in all the tests I conducted, I can not be sure that it will behave as desired or expected in all cases! I did not have access to HP's (Novadigm's) internal specification of the protocol, and the implementation of NvdmAPI is just based on pure speculation. So if you should be looking for a way to re-engineer Radia's protocol by re-engineering my Java code, you are on the wrong track! :-)

By the way: if you really want to look at the definitive protocol implementation, you probably know that there are much simpler ways than re-engineering my Java code or trying to draw conclusions from the TCP logging... I don't want to discuss this here in detail, but it is easy to look at HP's (Novadigm's) own Tcl source code -- no tricks, no hacks involved. But once again: that's not what I did! (I don't like Tcl ;-)
