increase virtual memory

szhiyong — Mon, 11 Mar 2002 09:26:29 GMT

Hi,

I want to increase the virtual memory in the HP/UX 10.20.

Would someone tell me the precedure of increasing virtual memory to 400MB? There is only 200 MB virtual memory in my workstation.

Thanks a lot for your help.

Hi Szhiyong,

easiest way is to use SAM:

disks and file systems

--> add logical volume
--> use as swap space
--> define size as 200 MB

When leaving the menu, SAM tells you he will create a new kernel because he needs to change a configurable parameter:

maxswapchunks will be set to a bigger value ( old_value+100=new_value

After this, you have to reboot your system, that's it....

Allways stay on the bright side of life!

Hi Szhiyong,

you can use the swapinfo- command to do so after rebooting the computer.

swapinfo -a

Displays information about all defined swap areas.That command should show you the new total size of swapspace. In another posting you told, you want to increase memory. Please remember, a good size of swapspace is:

amount_of_RAM * 2 (up to * 2.5)

so if you have a RAM- amount of 256 MB, take care to use round about 512 to 640 MB swapspace.

Allways stay on the bright side of life!
