ex. top in oracle environment

Below I have put the top output of a system running an oracle database
with two instances. At this time there was only a handful of users in
either of the instances total and most are relatively idle. Noone at
the time was doing any heavy transations or loads.

My question is that with the above given is it normal to have over
2gb of swap in use? Comments and suggestions for things to check would
be greatly appreciated. Thank you.
