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_txn()
are automatically logged to syslog
.
If the tunables being changed through
settune_txn()
are used in expressions that set the values of
other tunables, those expressions will not be re-evaluated and those tunable values will not be updated.
This behavior may change in future releases of HP-UX. If expression evaluation is desired, use
kctune()
to set tunable values.
Tunable changes made using
settune_txn() may not remain effective across reboots. This behavior
may change in future releases of HP-UX. If persistence of changes across reboots is desired, use
kctune() to set tunable values.
