HP-UX Reference (11i v2 03/08) - 2 System Calls (vol 5)

s
settune(2) settune(2)
[EIO] The Kernel Registry Service was unavailable or encountered an error.
[ENOMEM] Insufficient memory to accommodate the new parameter value.
WARNINGS
The caller must have super-user permissions to use this call.
It is possible to seriously degrade system performance, or even render a system unbootable, with incorrect
tunable settings. Use care when setting tunable values. Always have a known working kernel
configuration saved as a backup; if the system fails to boot after a tunable change, boot from that backup
kernel configuration. Keep good records of all tunable changes so that they can be reversed if they
degrade system performance. (Tunable changes made with
settune() are automatically logged to
sys-
log.)
AUTHOR
settune() was developed by Hewlett-Packard Company.
