Tunable Kernel Parameters
NAME [Toc] [Back]
create_fastlinks - configure the system to use fast symbolic links
VALUES [Toc] [Back]
Minimum
0
Maximum [Toc] [Back]
1
Default [Toc] [Back]
0
Specify integer value.
DESCRIPTION [Toc] [Back]
When create_fastlinks is nonzero, it causes the system to create HFS
symbolic links in a manner that reduces the number of disk-block
accesses by one for each symbolic link in a path name lookup. This
involves a slight change in the HFS disk format, which makes any disk
formatted for fast symbolic links unusable on Series 700 systems prior
to HP-UX Release 9.0 and Series 800 systems prior to HP-UX Release
10.0 (this configurable parameter was present on Series 700 Release
9.0 systems, but not on Series 800 HP-UX 9.0 systems).
To provide backward compatibility, the default setting for
create_fastlinks is zero, which does not create the newer, faster
format. However, all HP-UX 10.0 kernels (and all Series 700 HP-UX 9.0
kernels) understand both disk formats, whether "create_fastlinks" is
set to zero or non-zero.
WARNINGS [Toc] [Back]
All HP-UX kernel tunable parameters are release specific. This
parameter may be removed or have its meaning changed in future
releases of HP-UX.
Installation of optional kernel software, from HP or other vendors,
may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended
values. For information about the effects of installation on tunable
values, consult the documentation for the kernel software being
installed. For information about optional kernel software that was
factory installed on your system, see HP-UX Release Notes at
http://docs.hp.com.
