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> USE disk:[SYSn.SYSEXE]VAXVMSSYS.PAR
SYSGEN> SET PQL_DPGFLQUOTA value
SYSGEN> SET VIRTUALPAGECNT value
...
SYSGEN> WRITE disk:[SYSn.SYSEXE]VAXVMSSYS.PAR
SYSGEN> 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.
