In other words: if you have files that lay around in /tmp. this just eats up swap.
Yes you are right, it is anonmem. But for those without swap configured, it is equal to RAM.
It is recommended to have a swap that is 2x the size of the RAM.
No, it is not. Not in Linux. That reccomendation came from Windows.
Where is that recommendation documented?
I'm quite sure I read that in the manuals of SLES 9.
Most likely from that time, yes. It was a good rule of thumb when suspend to disk was in it's early shoes, and Desktop systems needed more space for that on disk than with nowadays implementation. Keep in mind, memory was much less per system in those times, too.
swap partition, while the newer SAP HANA hosts have 1 or 2 GB swap. If a HANA host starts to swap to disk, you should get out a shovel and dig your tomb :)
I'm not sure you wil have time to finish digging ;) Stefan
