Disk Defragmentation?

» close window

The Question is:

 
I have a Dec 3000 alpha station.  It is running OpenVMS 7.2.  How can I set up
 the disk defragmenter?
 

The Answer is :

 
  The answer depends highly on which defragmentation package you have.
 
  Please check the documentation for the defragmentation package.
 
  OpenVMS itself does not include an integrated disk defragmentation
  package, the usual approach -- when a specific defragmentation tool
  is not installed -- is to use the BACKUP/IMAGE tool to offload and
  then reload the contents of the target disk.  This also provides a
  known-good and known-consistent copy of the target disk, of course.
 
  Additionally, applications and processes can be set up to reduce
  incidence of disk fragmentation -- both through proper settings of
  the extend size and allocation size settings, and by providing
  sufficient free space on target disks, and by keeping the long-term
  (and growing) files stored separately from the more transient files.
