DESCRIPTION
The and tunables control when accounting stops and resumes due to disk
space constraints. When free disk space on the file system being used
by accounting reaches the suspension threshold, which is the percentage
relative to the percentage of disk space available only to the supe‐
ruser, accounting is suspended until such time as the free disk space
reaches the resumption threshold, which is the percentage relative to
the percentage of disk space available only to the superuser.
Note: Since the and values are specified relative to the per‐
centage of disk space available only to the superuser, negative
values of these parameters can make sense. For example, if the
superuser has reserved 10 percent of the disk space on the file
system at file system creation time, and acctsuspend is -5 and
acctresume is 0, the suspension threshold will be 5 percent of
the total disk space and the resumption threshold will be 10
percent of the total disk space.
Who Is Expected to Change This Tunable?
Anyone using accounting.
Restrictions on Changing
Changes to this tunable take effect at the next reboot.
When Should the Value of This Tunable Be Raised?
Increasing either variable should be considered when it is necessary to
maintain a higher percentage of free space on the accounting filesys‐
tem.
What Are the Side Effects of Raising the Value of This Tunable?
The higher either value is, the less accounting data may be captured.
The further the values are separated, the greater the amount of poten‐
tially lost accounting data.
When Should the Value of This Tunable Be Lowered?
If additional disk space is needed for accounting data, and it cannot
be obtained by moving files off of the filesystem, then the value of
should be lowered.
What Are the Side Effects of Lowering the Value of This Tunable?
Filesystem performance (writing accounting records) decreases as the
filesystem fills up. In turn, this will decrease the overall perfor‐
mance of accounting processes.
What Other Tunables Should Be Changed at the Same Time?
When changing either of these tunables, both should be considered.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parame‐
ter may be removed or have its meaning changed in future releases of
HP-UX.
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.
