Obsolescence

The following has been deprecated in HP-UX 11i v2, and will be obsolete in post-HP-UX

11i v2 releases:

•The MAXSYMLINKS literal traditionally included in the <sys/param.h> header is

being deprecated in HP-UX 11i v2 and should not be used by applications.

MAXSYMLINKS was defined as the maximum number of symbolic links that may be

expanded in a path name.

This limit (number of symbolic links that may be expanded in a path name) is now a

tunable parameter: fs_symlinks. The interfaces provided by the tunable

infrastructure should be used to obtain the value of fs_symlinks. At the application

level, for example, use the gettune (2) or kctune (1M) interfaces.

Applications using the MAXSYMLINKS literal may not be consistent with the kernel.

The MAXSYMLINKS literal will be removed from <sys/param.h> in post-HP-UX 11i v2

releases.

• All tunables associated to the buffer cache (nbuf, bufpages, bufcache_max_pct,

dbc_min_pct, and dbc_max_pct) are still supported through HP-UX 11i v2, but will

be obsolete in future HP-UX releases. The dbc_min_pct and dbc_max_pct tunables

will be replaced with new dynamic tunables that will control the amount of memory

to be used for file caching in general (for caching file I/O data and metadata).
