hiii all


how to modify the requiered kernal parameter to match the new memory size on hp-ux

Hi,

you can use kmtune, sam.

But please make sure that KP are dependent on few more things like, OS, SWAP, RAM & your application requirements.

Final Note: KP would require a reboot.
So be careful in changing them & for a beginer SAM is best.

Hi,

I think you are refering shmmax? Do it on SAM (with root, write "sam").

Hi Fahad,

If you upgraded any Physical RAM, better to increase the SWAP space which should be atleast 2 times to RAM size. And Modify the Kernel Paremeter MAXSWAPCHUNKS to match SWAP size using SAM or kmtune.

If you are specific sharedmemory paremeters to be modified like shmmax, shmmni, semmns, semmni use SAM and rebuild the kernel.

Thanks & Regars,
