In several (earlier) books I have on Corba and lots of product
literature, I had seen no reference to IIOP. I'm glad to hear it was
there, but the vendors involved must have buried it enough that I
couldn't find it.
CORBA has NOT become as popular as it should be for one very simple
reason: there were no usable public implementations for us to play
with.
That, and the former dearth systems using a standard wire format, have
held it back. Now DCOM has a wide following...
Sybase is an example where they are holding onto the wire format to
have control over clients to their database. I can tell you that
their clients are not as good as they could be (CT_Lib took 80% of the
CPU in one large server that I wrote). I happen to have the spec for
the TDS protocol, but normally it's not public. Of course it's
interesting that MS's SQL Server is still using TDS, and was and/or is
based on an earlier Sybase engine. MS of course doesn't usually
benefit from publishing protocol specs.
Oracle on the other hand has had a published wire format for quite a while.
