Synopsis
dynamic_pager [-E] [-Ffilename
] [-Hhire_point
] [-Llayoff_ point
] [-Ppriority
] [-Sfile_size
]
Manages virtual memory swap files. This tool is started from /etc/rc during the boot process.
Starting with Panther, when dynamic_pager is invoked without -H, -L, or -S options, it creates swap files that are sized dynamically according to paging needs and available disk space.
Options
- -E
Encrypt the swap file.
- -F
Specify the base absolute pathname for swap files. Swap filenames consist of this base and a whole number suffix, starting at 0. The default is /private/var/vm/swapfile.
- -H
Create an additional swap file when free swap space drops below the
hire_point
in bytes. The default is 0, which disables the use of this swap space.- -L
Attempt to consolidate memory and remove a swap file when free swap space rises above the
layoff_point
in bytes. Thelayoff_point
must be set higher than the sum of the swap file size and thehire_point
, unless it is set to 0 (the default), which disables layoffs.- -P
Determine the priority of this swap space. The default is 0.
- -S
Determine the size of swap files created, in bytes. The default is 20000000.
