Right now, the production system runs on OpenVMS VAX V6.2.  The primary 
applications are written in Digital Ada.  The Sybase piece has a C wrapper 
that is called by the Ada code.  The particular programs where we have the 
disconnect issues sit and wait for messages from a message queue using 
Digital's DECmessageQ product.  Once the messages are received, they are 
processed and sent on to Sybase.

We have a loaner Itanium system from HP where we are testing out various 
pieces of code that will give us some confidence that a complete move from 
the VAX to Itanium hardware will be successful.

The main changes are:

OpenVMS VAX V6.2 - OpenVMS Itanium V8.3-1H1
UCX V4.2 to HP TCP/IP Services V5.6 - ECO 3
Digital Ada to GnatPro supplied by AdaCore
Sybase client 10.0.1? to FreeTDS 0.82
DECmessageQ V3.2 to BEA/Oracle MessageQ V5.0
DEC C V5.6-003 to HP C V7.3-018 (just the wrapper program referenced 
above, and of course FreeTDS)

All code is being recompiled/linked and we are not using a binary 
translator.

We do have some Alphas, but it would be a major undertaking to try to get 
this same environment running under Alpha as we do not have Alpha versions 
of all the needed products.
