The following notes are taken from the Technical Support FAQ area on 
Wolfram Research's World Wide Web pages.


How do I get the VMS kernel to connect to a remote front end?

Remote kernel connections are only supported in VMS under UCX 2.0. 
While Mathematica may be able to make remote kernel connections 
under other TCP implementations, we have not tested those 
configurations and can't say whether or not they will work. It has 
been our experience from customer feedback that remote kernels do 
not work under MultiNet. 

You should follow the instructions which came with your front end 
to set up the remote kernel connection. You will need to make some 
slight adjustments for VMS, however, based on which method you are 
using. If you are attempting to launch the kernel from the VMS 
command line with command-line arguments, you need to make the 
following changes to the commandline arguments: 

OpenVMS     | Unix Equivalent
/MATHLINK   | -Mathlink
/LPROTOCOL  | -LinkProtocol
/LMODE      | -LinkMode
/LHOST      | -LinkHost
/LNAME      | -LinkName
/LOPTIONS   | -LinkOptions

Note that for options which take an argument, such as -linkprotocol 
Listen, you need to use an equal sign (=) for the VMS command line. 
For example: 


If you are launching the kernel through the Kernels and Tasks dialog 
box, then you need to set up the Basic Options section as you would 
for any kernel, switch to Advanced Options, and make the substitutions 
outlined above for the "String passed to shell to launch kernel" or
"Communications toolbox login" section. 

If you are making the connection by launching Mathematica on the VMS 
machine and altering the $ParentLink variable, then no changes need 
to be made in the procedure to set up a remote kernel.


If you need further help with this I would suggest that you contact
Wolfram Research Technical Support directly (support at,
support-europe at in Europe or support-asia at in Asia).

They are searchable by keyword and include answers to many of
the common questions answered by Wolfram Research Technical

I hope this helps.
