During Sun Solaris 8 installation, I did allocate 1 G for the swap partition. By doing a "df -k" shows the swap space usage is only 1% even during the application server is heavily processing.
However, when I do a "vmstat", it shows that the swap memory free space is only 8816 out of 1419100.

mkfile(1M) mkfile(1M)
NAME
mkfile - create a file
SYNOPSIS
mkfile [-nv] size [g | k | b | m] filename...
mkfile creates one or more files that are suitable for use as NFS-mounted swap areas, or as local swap areas. When a root user executes
mkfile(), the sticky bit is set and the file is padded with zeros by default. When non-root users execute mkfile(), they must manually
set the sticky bit using chmod(1). The default size is in bytes, but it can be flagged as gigabytes, kilobytes, blocks, or megabytes, with
the g, k, b, or m suffixes, respectively.
-n Create an empty filename. The size is noted, but disk blocks are not allocated until data is written to them. Files created with
this option cannot be swapped over local UFS mounts.
-v Verbose. Report the names and sizes of created files.
USAGE
See largefile(5) for the description of the behavior of mkfile when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
