How to increase stack size

Vengat — Tue, 30 Oct 2012 06:55:33 GMT

Hi Team

Kindly let me know how to increase stack size ( hard limit ) and let me know the maximum size of stack.

Operating system : 11.31 U ia64

Current stack size : stack(kbytes) 392192

Memory : dmesg |grep Physical
Physical: 33522972 Kbytes, lockable: 25024276 Kbytes, available: 28498500 Kbytes

Question 1 : - what is the maximum stack size will allow ? -

Question 1 :- How to set ?

if it is user process stack:

man maxssiz

    Allowed values
      32 bit minimum: 0x40000

      32 bit maximum: 0x17F00000

      64 bit minimum: 0x40000

      64 bit maximum: 0x80000000

This is already way too large, unless you have some Fortran app.

Increasing maxssiz will decrease the amount of maxdsiz, if you have already increased it 4 GB.

>1: what is the maximum stack size will allow?

32 or 64 bit?

>2: How to set?

kctune maxssiz= or kctune maxssiz_64bit=
