UpStare 0.10.9 (Default branch)
UpStare is a dynamic software updating system (compiler, runtime, and patch-generator) for multi-threaded userspace applications. It allows semi-automatic updates to programs that could not be updated with existing approaches, or could be updated with a possibly indefinite delay between the time an update is requested and the time the update is applied. The approach can replace functions active on the stack by applying stack reconstruction, which can update program state and program code immediately in a single step. This obviates the need to rely on statically determined safe update points, which might not exist, and can update server-side code without closing client connections.License: Free for non-commercial useChanges:
This release considerably improves the ability of the patch generator to automatically produce stack transformers and incorporate user-defined stack transformers. It also implements support for blocking system calls in a much more efficient way.Image

NAME

       pci_error_tolerance_time - time interval, in minutes, between two PCI errors at a I/O slot that will result in automatic PCI Error Recovery

VALUES

   Default
   Allowed values
       (disabled) or non-zero (enabled)

   Recommended values
DESCRIPTION

       is  a dynamic tunable that corresponds to time interval in minutes.  It determines whether an automatic PCI Error Recovery should be initi-
       ated or not between two PCI errors occurring at an I/O slot.  If two PCI errors occur at a slot within this specified  time  interval,  the
       PCI  card  in  the  slot will be suspended and a manual PCI Error Recovery operation will have to be performed to make the card functional.
       Refer to the section of the olrad(1M) manpage for more details regarding the manual PCI Error Recovery operation.

   Who Is Expected to Change This Tunable?
       System administrators can change the value of based on the frequency of PCI errors seen in the system.

   Restrictions on Changing
       None.  This tunable is dynamic.	Changes to this tunable take effect immediately.

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
