Task-to-Task communications?

» close window

The Question is:

 
Where can I find installation information about Task To Task (TTT). I have
been trying to locate details on the web. Is there a DEC manual available
for TTT or is the information already in one of the system manuals?
 
What I am trying to find out is how TTT collects test data from a PC test
environment to enable us to create a test system, using our own test station
simulation routines from a PC.
 
 

The Answer is :

 
  DECnet task-to-task communications are documented in the DECnet manuals.
 
  In the Wizard's experience, the requirements might initially appear far
  more imposing than they actually are in practice -- if you are familiar
  with using sys$qio[w] calls and I/O operations, DECnet task-to-task is
  quite simple.
 
  TCP/IP can also be used to perform task-to-task communications, though
  communications over TCP/IP are more commonly refered to as socket
  communications.  Information on the TCP/IP interface is available in
  the TCP/IP Services for OpenVMS documentation and in the DEC C manuals.
  Socket programming can be performed using the C language, and can also
  be performed using the sys$qio interface.
 
  Some information on the remote end of the connection will also be
  required.  This could be PATHWORKS DECnet or similar, or it could be
  performed via TCP/IP sockets.  Check the programming documentation for
  PATHWORKS or for the base operating system for details.
 
  Example programs include SYS$EXAMPLES:DB*.C, as well as simple DCL code
  examples such as the "DCL Task-to-Task?" discussion here in Ask The
  Wizard -- the Digital Press book (an imprint of Butterworth Heinemann;
  URL http://www.bh.com) _Writing Real Programs in DCL_, second edition,
  covers DCL task-to-task.  For TCP/IP examples, see UCX$EXAMPLES: (prior
  to V5.0) or TCPIP$EXAMPLES: (in V5.0 and later).
