DESCRIPTION
This tunable dynamically enables (1) or disables (0) the online shared
library debugging feature. When this tunable is enabled, shared
libraries of a running (active) application can be debugged.
Who Is Expected to Change This Tunable?
System administrators and developers who want to change the default
behavior of
Restrictions on Changing
Changes to this tunable take effect immediately. There is no need to
reboot the system.
When Should the Tunable Be Turned On?
When there is a need to debug a shared library of a running (active)
application, this tunable can be turned on.
When this feature/tunable is not enabled, debugging of shared libraries
can be done at application start time through the command. See
chatr(1).
What Are the Side Effects of Turning the Tunable On?
If an application which is being debugged for shared libraries is not
MPAS (Mostly Private Address Space) executable, then the application
will be converted to an MPAS executable type. After the conversion,
all rules which apply to regular MPAS executable type does apply to the
converted application until the process exits. The rules apply even
after being detached from the debugger.
When Should the Tunable Be Turned Off?
Administrators and/or developers who will not need the online debugging
feature of shared libraries.
What Are the Side Effects of Turning the Tunable Off?
When this tunable is disabled, then online debugging of shared
libraries will not be possible beyond the existing hardware break point
facility. With hardware break points, only a limited number of break‐
points can be set.
What Other Tunables Should Be Changed at the Same Time?
None.

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‐
