HP OpenVMS Systems

Application Communications via OPCOM? (CA)

» close window

The Question is:

 
We are installing CA Unicenter as an enterprise wide management system, and
as one segment of the project wish to send non-time-critical health status
messages from our time critical real-time data acquisition system to
Unicenter via OPCOM. Unicenter then
 processes these messages and takes approriate actions
 
I have two questions:
 
1. Does the Wiz see significant overhead in sending messages to OPCOM in a
real-time environment ?
 
2. I see that $SNDOPR returns successfully when an OPCOM message is sent
with no specific destination operator specified. Does this ever get to OPCOM
(I know it doesn't appear at a any terminals) ? If not, is there any
mechanism to send OPCOM messages whi
ch avoids bringing up messages on terminals ?
 
Thanks from down under

The Answer is :

 
  There is no particular single definition of "real time", as each site
  and each application can have its own unique response time design
  requirements.
 
  If OPCOM works, then use it.  If it does not meet your specific real-time
  requirements, you will need to discuss these with CA and with Compaq
  Customer Support Center.
 
  OPCOM is not particularly designed for communications between programs
  -- OPCOM is designed as a way for an application to communicate with a
  human operator.  The recently released event services that are provided
  for use with OpenVMS V7.2 -- and specifically for use with OpenVMS Galaxy
  -- would likely be closer to meeting the requirement for communications
  between applications.)
 
  Please contact CA for assistance with this question, and with available
  options for interfacing applications and application information into
  the CA environment.
