  Standalone BACKUP parameters? (Insuff. Quotas) 
 The Question is:
 
 
When trying to perform standalone backup on
the machine says:
Insuficient quota...check BYTLM...
 
Please help.....
 
 
 The Answer is:
 
  Please contact the customer support center for assistance.  Expect to
  be asked more about the version of standalone BACKUP in use, and the
  particular BACKUP command specified.
 
  If you wish to proceed without the assistance of the customer support
  center, please perform a conversational bootstrap and increase the setting
  of the PQL_DBYTLM parameter, or please try a version of standalone BACKUP
  for a more recent version of OpenVMS.
 
  For OpenVMS VAX V5.5-2, the Wizard would expect the following parameters
  ratios and values:
 
    WSQUOTA        16,384
    WSEXTENT       Greater than or equal to WSQUOTA
    PGFLQUO        32,768
    FILLM          128
    DIOLM          4096
    ASTLM          4096
    BIOLM          128
    BYTLM          65,536
    ENQLM          256
 
  Here are the relationships among the major parameters:
 
    o WSQUOTA, WSEXTENT, and WSMAX should be set to the same value.
      (SYSGEN parameters: PQL_DWSQUOTA, PQL_DWSDEFAULT, WSMAX)
 
    o PGFLQUOTA should be at least 3000 above WSMAX, and set to the same
      value as VIRTUALPAGECNT.  (SYSGEN parameters: PQL_DPGFLQUOTA)
 
    o Set CHANNELCNT large, to allow as many parallel I/O channels as
      possible.  Set FILLM to at most (CHANNELCNT - 15), and never higher.
      BIOLM should be less than or equal to FILLM.  ENQLM should be greater
      than FILLM.  (CHANNELCNT, PQL_DFILLM, PQL_DENQLM)
 
    o Increase the DIOLM value as necessary to keep I/O operations
      running in parallel as much as possible.  Set ASTLM to at least
      the same value as DIOLM, and never lower.  (PQL_DDIOLM, PQL_DASTLM)
 
    o BYTLM is limited to the amount of non-paged pool available before
      the BACKUP starts, and should be set to at least (256 * FILLM) +
      (6 * DIOLM).  (PQL_DBYTLM, NPAGDYN, PQL_DFILLM, PQL_DDIOLM)
 
  You can also modify these values directly on a version of standalone
  BACKUP written to a (writeable) randomly-accessable media (a disk, in
  other words) by using the follong SYSGEN commands from a running copy
  of OpenVMS:
 
    $ RUN SYS$SYSTEM:SYSGEN
    SYSGEN&gt; USE disk:[SYSn.SYSEXE]VAXVMSSYS.PAR
    SYSGEN&gt; SET PQL_DPGFLQUOTA value
    SYSGEN&gt; SET VIRTUALPAGECNT value
    ...
    SYSGEN&gt; WRITE disk:[SYSn.SYSEXE]VAXVMSSYS.PAR
    SYSGEN&gt; EXIT
 
  Be certain to carefully specify the disk:[SYSn.SYSEXE]VAXVMSSYS.PAR
  file, as it must be the version of the file in the SYSn system root
  specifically used for standalone BACKUP, and obviously on the device
  used to bootstrap standalone BACKUP.
