I have my sga (612MB) and shared_pool_size(90MB) sized fairly large, however I still have a hefty amount of paging occurring when I execute simple, large joins. Is this paging indicative of a poorly tuned SGA, OS, or is it a normal occurrence while executing a large join? The issue lays in the fact that my joins are taking waaaaay to long, and I really don't feel that it's a sql issue. Thanks!

More information would be good, for any diagnosis for performance tuning.
To start with, try the following:
1. Increase the temp segments and make sure the temp tablespaces are used
2. Increase the sort_area_size and
sort_area_retained_size
3. Make sure the indexes are properly used.
