RH Linux vm.swappiness kernel parameter

428547Jan 5 2010 — edited Jan 5 2010

The linux kernel parameter vm.swappiness affects the tendency of the OS to swap. It has a range from 0 to 100, with 0 causing swapping to occur only when needed and 100 to swap more aggressively. The default setting is 60.

There is little information available regarding an appropriate setting for this for Oracle RAC nodes. Do any of you have experience with swappiness? I have seen a few articles which recommend setting it to zero (0).

Best regards,
Bill
