OrbixWeb 3.0.x is ancient and quite different to the other IONA
products. On page 408 of the OrbixWeb programmers guide in the section
titled "multithreaded servers" it says (and I quote):
Where parallism is not required, there is no need to make a server
The way I read this is that by default a server is single-threaded,
you have to write some extra code (e.g using thread filters) to make
it multi-threaded. I have discussed this with an IONA consultant, who
reads this the same way I do. But our OrbixWeb setup seems to
dispatching CORBA requests from more than one thread.
I am using the apache commons logger which reports the thread name in
each logging record. When I log the incoming CORBA request I see two
thread names, one is "main" which I expect since that is where my call
to processEvents is, the other is called "Request Processor". I don't
know where that thread comes from. It's not one of mine.
