-V{n} Display or alter the default size of the virtual memory buffer
table (VFS) allocated for each line. The optional parameter
n is a number between 20 and 256. Used without the
numeric parameter, the size of virtual memory buffer table is
displayed. For example:
./prodpick -V
Current VFS = 36; Map = 1; Sequence = 0;
Adjusted lines = 0;
where
Current VFS is the size of the VFS table allocated
per process,
Map is the number of virtual memory buffers
mapped per VFS table entry,
Sequence is the number of
times the size of the VFS table has been modified, and
Adjusted lines is the number of processes that modified
their VFS table to the current size.
Used with the numeric parameter, the current size of virtual
memory buffer table allocated for each line is altered. All
processes whose VFS is greater than or equal to the VFS
specified in config are permitted to increase their VFS by
the difference between the config VFS size and the new
current VFS size.
For example, if the VFS size specified in config is 36, the
following command alters the current VFS by 12:
./prodpick -V48
Current VFS = 48; Map = 1; Sequence = 1:
Adjusted lines = 0;
Processes whose VFS is greater than or equal to 36 (the VFS
specified in config) are permitted to increase their VFS by
12 (the difference between 48 and 36). In this example,
processes started with the default 36 VFS are increased to
48. Processes started with a VFS of 64 are increased to 76.
Processes whose VFS is less than 36 never adjust their VFS.
-M{n} Used in conjunction with -V to adjust the number of virtual
memory buffers mapped per VFS table entry. Valid entries
for parameter n are 1, 4, 8, 16. The total number of virtual
memory buffers allocated per line is equal to the VFS table
size times the number of buffers per VFS table entry. The
command ./prodpick -V64 -M4 causes the default number
of virtual memory buffers for each line to be 256.
-w Set warmstart flag. Should only be used when machine has
been warmstopped.
