HP-UX Buffer Cache Tunable Parameters Deprecated
deprecated for
June 2004
Now deprecated are the following tunables associated with the sizing of the buffer cache:
• nbuf
• bufpages
• bufcache_max_pct
• dbc_min_pct
• dbc_max_pct
These tunables are still supported in HP-UX 11i v1 and HP-UX 11i v2 releases, but will
be obsolete in future HP-UX releases (HP-UX 11i v3 and later).
Customers that migrate to HP-UX 11i v3 will no longer be able to use the buffer cache
size tunables. An error will be produced in HP-UX 11i v3 if the you attempt to use the
buffer cache size tunables; this includes system files or scripts that use these tunables.
The manpages for the buffer cache tunables will be updated with HP-UX 11i v3 to
indicate that they are obsolete. New file cache tunable manpages will be delivered with
HP-UX 11i v3.
