NAME

       max_acct_file_size - defines the maximum accounting file size

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
DESCRIPTION

       is  a dynamic tunable that limits the maximum accounting file size.  See acct(2) and acct(4).  If was set to a value that is not a multiple
       of the accounting record size, the tunable will be rounded up to the next full record silently unless the maximum  limit  is  reached.	In
       this case, the tunable will be rounded down to the nearest full record silently.

       The only exception to this rule is when the is set back to its default value.  The system will accept 2,560,000 without rounding up even if
       it was not a multiple of the accounting record size.  This is done to preserve binary compatibility with previous releases of HP-UX.

   Who is Expected to Change This Tunable?
       System administrators that wish to allow accounting files to grow beyond the default.

   Restrictions on Changing
       None.

   When Should the Value of This Tunable Be Raised?
       If there is a need for larger accounting files than the default.

   What Are the Side Effects of Raising the Value?
       Accounting tools that assume accounting files no more than 2.5 MB in size might not be able to handle larger files.

   When Should the Value of This Tunable Be Lowered?
       The default value is also the minimum value.  If the value of was raised it can be  lowered  again  if  large  accounting  files  were  not
       desired.

   What Are the Side Effects of Lowering the Value?
       None.

   What Other Tunable Values Should Be Changed at the Same Time?
       None.

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter 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 values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at

NAME

       tcphashsz - determines the size of the networking hash tables

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
       A  value  of  0	(default) will adjust the in proportion to the number of cores in the system.  If is set to a non zero value, it should be
       specified as a power of two.  Otherwise, it will be rounded down to the nearest power of two.

DESCRIPTION

       This variable is used to set the size of the networking hash tables.  HP recommends that the value of be set to 0 so that  the  system  can
       choose  an  optimal  value.   A	system	that  is going to have a large number of connections on it all of the time may see some benefit of
       increasing this value, beyond the number determined by the system.

       If this tunable is not set to zero, then it needs to be a power of two.	If it is not specified as a power of two, then it is rounded  down
       to the nearest power of two.  If this tunable is set in the range of 1 to 255, then it will be increased to 256.

   Who Is Expected to Change This Tunable?
       Anyone.

   Restrictions on Changing
       Changes to this tunable take effect at the next reboot.

   When Should the Value of This Tunable Be Raised?
       This value may be raised in the case of a machine with a large number of connections that last for an extended period of time.

   What Are the Side Effects of Raising the Value?
       More memory is used when this value is raised.

   When Should the Value of This Tunable Be Lowered?
       If a system is tight on memory and it has just a few connections on it, then lowering the value may reclaim some memory.

   What Are the Side Effects of Lowering the Value?
       If is set too low, the system will have long hash chains which will slow it down.

   What Other Tunables Should Be Changed at the Same Time?
       None.
