NAME

       maxtsiz, maxtsiz_64bit - maximum size (in bytes) of the text segment for any user process

VALUES

   Default
   Allowed values
DESCRIPTION

       User  programs  on  HP-UX  systems  are composed of five discrete segments of virtual memory: text (or code), data, stack, shared, and I/O.
       Each segment occupies an architecturally defined range of the virtual address space which sets the upper limit  to  their  size.   However,
       text, data and stack segments may have a smaller maximum enforced via the and tunables.

       controls  the  size  of the text segment, which is the read-only executable object code for the process that can be shared by multiple pro-
       cesses executing the same program.  For example, all copies of vi on the system use the same text segment.

   Who is Expected to Change This Tunable?
       Anyone.

   Restrictions on Changing
       Changes to this tunable take effect immediately. The size is expected to be a multiple of the base page size. See  the  description  of	in
       getconf(1) for more details.  If the value specified is not a multiple of the base page size, it will be rounded down to the nearest multi-
       ple of the base page size.

   When Should the Value of This Tunable Be Raised?
       should be raised if user processes are receiving the error with the following message:

       or
   What Are the Side Effects of Raising the Value?
       None.

   When Should the Value of This Tunable Be Lowered?
       This tunable should be lowered to limit the text size of running processes; there is no system performance reason to do so though.

   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
