We are running an oracle database on an 8400 with 2G RAM. The
database has an SGA of 1.3G - the idea is to run as much in memory as
possible. We are running in over-committment mode and when the
database is busy, swap space begins to be taken up as you would
expect. However, when the database is quiet again the swap
utilisation remains the same, often leaving very little spare.
My question is: when do allocated pages of swap get freed up again?
Is it only when the process owning them dies or when they are paged
back into real memory? Or through some other mechanism altogether?
Any info/thoughts would be gratefully received.
Thanks in advance, Nick
