HP Raining DataCorp. mvEnterprise Prodpick, Current VFS = 36 Map = 1 Sequence = Adjusted lines =

-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 -Vto 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-M4causes 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.
