Hello,
Thanks for your tip.
I installed 2.4.17-rmap-11c and later 2.4.17-rmap-12a on my
2-CPU-Pentium-III
and on one of my 4-CPU-Xeon-III's, and since then, the machine isn't
swapping any
longer.
I use Informix 7.3 and Oracle 8i.
When i used the standard kernel with informix in former times, i had to
reboot often, if there was much traffic on the machine.
I switched to Andrea's kernel patches, from then I hadn't to reboot, but the
backup
(including database consistency check) took 5 hours, and the swap file was
around 200M,
although there was enough RAM (3G)
According to your idea, i switched to 2.4.17-rmap-series.
I don't have to reboot any more, informix runs well, the backup takes only 1
hour 20 minutes,
there is no swap space any longer used.
Thanks to you and Rik van Riels!
I would like if Rik's kernel patches would go into standard.
They are really well!
Martin

Subject: kernel 2.4.17 with -rmap VM patch ROCKS!!!
Hi!
I installed kernel 2.4.17 on my SMP server with 8CPU's and 8GB RAM
and lets just say that whenever the entire physical memory was utilised
the box would topple over...with kswapd running a havoc on CPU
utilization
So to avoid losing control I had to reboot every 8 hours.
But, it all changed after I applied Rik van Riels 2.4.17-rmap-11c patch
Now, the box is happily running for the past 3 days under heavy load
without any problems. The RAM utilization is always at about 95% +
but the system doesnt swap at all.....kswapd is running all the time
and
freeing up main memory for other processes. I am quite happy with the
performance of the box........and highly recommend Rik's patches
for anyone else facing similar problems
Thanks to all you guys, especially Rik for helping me out....
Best regards,
Anish Srivastava
