Seeking high performance file I/O?

The Question is:

 
Does DECram support the reserved memory feature introduced in OpenVMS 7.0? If
 so, does that mean that the combo can be setup to allow non-paged access to
 data files in memory by file specification? Never touching the disk? Is this
 the way to go to obtain
the fastest access possible to data files by filespec from user processes? Are
 there plans to enhance DCL INSTALL to also support data files and not only
 image files?
Thank you very much.

The Answer is :

 
  Direct access to internal DECram data structures is not supported and not
  recommended, and the interface and the structures involved are not ones
  that the OpenVMS Wizard would expect to remain consistent.
 
  INSTALL has always dealt correctly with and has supported the installation
  of various data files (qv: COMMONs), but RMS global buffers would be the
  most commonly recommended approach for non-image-format data files.
  (INSTALL is part of the user interface for the OpenVMS image activator.)
