1 SCRATCH 
The USR$SCRATCH disk, with large quotas for all users, should be used
for the temporary storage of files which are too large to be stored
within the quotas available on the permanent disks. The USR$SCRATCH disk
is not backed up by the scheduled system backups, and files will be
periodically deleted, according to announced policies, by the management.
Do not place any file on the Scratch device which cannot be regenerated
or recovered from independent sources.

Directories are established on USR$SCRATCH for all users. If you find
that you do not have such a directory ,contact a consultant or GRIPE for
assistance in having the directory established. 

Currently, files over a threshold product of size and days since last access
are being removed from the scratch device daily.  The BLOCKDAYS utility may
be used to obtain a sorted list of your current files. First set up the
product with @BLOCKDAYS_COMMANDS:SETUP, set default to the scratch device,
then type BLOCKDAYS.
