[olug] adding swapfile

[Noel Leistad]

been asked to add swap to "production system"

System manages to run w/ single "instance" of SAP, adding "second 
instance", system crashes. Owner suspects SWAP

target system running SAP

100MB /boot
130GB /
4G RAM
NO SWAP

Swap recommendations I've seen
4096MB RAM -- > 13300MB Swap??

SO, confirming:

dd if=/dev/zero of=/usr/tmp/newswapfile bs=1024 count=12583000

then

mkswap /usr/tmp/newswapfile

swapon /usr/tmp/newswapfile
