Welcome to the Forums.

My best suggestion is to see if your employer will pay for you to take a class. Then I highly recommend you purchase a book on HPUX Admin start reading! Or simply do a SEARCH here for something like 'increase kernel parm'. These questions have been answered many, many times.

SAM still runs in 11.23. Give it a try..

SMH replaced SAM in 11.31 and you can change parms from the SMH webconsole.

Or you can use the command line kmtune [man kmtune]

You enlarge swap by either adding f/s swapspace or mostly it is done by adding additional disk to vg00 and setting these disk as swapdisk. Do a SEARCH on 'add swap or add swapdisk' and check out the bounty of answers already posted here.

Rgrds,
Rita

It's kmtune in 11.23
It's kctune in 11.31

Sorry,

Actually you should use kctune(1m) on 11.23.
kctune maxdsiz=0x80000000 # 2 Gb
Note: maxdsiz_64bit must already be larger than that.

Use kctune parameter=value

3)how to enlarge Swap Size ??

Use swapon command. Swap space must be contiguous. Hence adding extra swap would be easier than enlarging.
