unlockable_mem(5) OBSOLETE unlockable_mem(5)NAMEunlockable_mem - OBSOLETE kernel tunable parameter
DESCRIPTION
The tunable is obsolete and has been removed.
Memory locking allows the privileged user to specify which pages need
to remain in memory, and unaffected by the swap process. This feature
allows you to ensure that memory access times are unaffected by delays
introduced by memory paging and swapping. For example, locking is a
tool provided to privileged users on a system that is short on physical
memory. Instead of having these privileged processes swap like the
rest of the processes, they can lock portions of their address space.
Once the pages are locked in for the privileged processes, they will no
longer have to worry about memory contention. The unprivileged pro‐
cesses however, will have to compete for memory.
provides you with a limiting factor on this privileged behavior, by
setting the amount of memory which cannot be locked by user processes.
WARNINGS
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 val‐
ues. For information about the effects of installation on tunable val‐
ues, consult the documentation for the kernel software being installed.

installed on your system, see at
