(Tunable Kernel Parameters)

When Should the Value of This Tunable Be Lowered?

This tunable should only be lowered if the workload for the PA-RISC emulator is known on the system,

more space than is needed is currently used for stack emulation, and swap space (either reserved or allo-

cated) is at a premium on the system.

What Are the Side Effects of Lowering the Value?

Lowering this tunable will decrease the available stack space for emulated PA-RISC binary executions.

Emulated processes needing larger stacks will fail stack growth requests (just as lowering

maxssiz or

maxssiz_64bit

may cause process termination due to failure to grow stack).

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 parame-

ter values. After installation, some tunable parameters may no longer be at the default or recommended

values. For information about the effects of installation on tunable values, consult the documentation for

the kernel software being installed. For information about optional kernel software that was factory

installed on your system, see HP-UX Release Notes at
