I recieved an email from a member who apparently does not know how to post, I'll do what I can to help on that, but in the mean time, here's their email:
We write software in acu cobol it is a point of sale software and the server is
running Suse 8.1 and the terminals get a remote login from bootp from a package
called hotkey which is dos based.
My problem here in south africa the electricity is really krap and ups's do fail
when a system is running alot of the swop space is used to cache the file being used
and when it crashes what ever is in the swop space or ram gets lost and on
recovering the data files the last 5 invoices are lost .
What i need to do is set the swop space the flush every so many seconds to the hard
Somebody told me there is a command like swop-on or swop-off how would i use this
command to see if it will improve our data loss
from mark bosch
They asked me to post this for them, and it seemed like a good question.
The only idea I have is that maybe the swap (spelled s-w-a-p) on swap off commands send the data to the HD, however I don't know if it writes it to a specific location or simply flushes it to somewhere randomly, or possibly even the RAM...
