If you have 12 gig of ram and do a core dump and it fills the dump partition the machine may not reboot properly. For normal running I would suggest 1 or 2 gig of swap is heaps, in reality if you use more than 500meg you are usually screwed anyway. > > > > The app is an LSAP system > 6G of data, > > > > JYard > > UCLA > The Rule of Thumb is normaly 1.5 - 2 times the physical amount of ram. that its was they tall you > So in your case 18 - 24g of swap. Thats its very stupid. I tend to agree. This rule of thumb was current when a machine had 32 or 64meg of main ram, it has little justification these days IMHO. why waste so much disk in something not worthy? I always says if you have a lot of RAM because you need it (Big DB) and you start to use to much swap (>512) better buy more RAM. > I would check to see if your app requires that much ram. as far as i know, there is not such thing like "much ram". My only concern is the core/kcore, I have had cores 100% a partition and the machine is then unstable. Advice off the application vendor might be useful, but from experience the helpdesk people you will talk to will not really know.
