We've recently started running Oracle 10g on SLES9 We were wondering why we are going into swap with 16G of ram and not much running on the machine except for Oracle.
Oracle does not use async I/O in the standard installation. You have to enable it (see http://www.grabinar.com/simon/aio.html). But I think you are seeing something completely different. Linux swaps out processes that have not run for a certain amount of time (because they are waiting for something or are just sleeping) even if there is memory available. They are consuming memory for nothing. You can see if your machine is really swapping (with performance impact) with the tool vmstat. So I think there is everything ok with your installation.
