Printing overhead, configuration, requirements?

» close window

The Question is:

How do I measure the impact of print queues on overall performance of an
 OpenVMS cluster? How do I identify bottlenecks? Will moving the print queues
 to a separate OpenVMS machine print server significantly reduce the load on
 the cluster nodes? How do I d
etermine the memory/disk/input-output/cpu requirements of the proposed print
 server if it has to handle 200 print queues (distributed over two campuses
 eight miles apart), 90% of which will be very lightly used? Are there any
 special interfacing requireme
nts for getting OpenVMS print queues (both ascii and postscript) to work with
 Xerox Document Centre copier/printers?

The Answer is :

  If printing and print queues are a performance-critical factor, your
  systems are marginally capable -- at best -- of handling your current
  application environment.  (The OpenVMS Wizard is aware of sites with
  thousands of print queues.)
  Please see the OpenVMS guide to performance management for details on
  a systematic approach toward locating and resolving performance-limiting
  The usual mechanism used for printing to Postscript printers involves the
  use of the DCPS package.  Beyond configuring any necessary transport
  software (eg: telnet, LAT, serial), no additional software is required
  for ASCII (or ISO Latin-1) printers.  As for what requirements exist for
  a particular printer, that is something the OpenVMS Wizard would have to
  determine from the particular printer documentation available.
  For general IP printing information, please see topic 1020.
