Every modern operating system does not swap entire processes. However, the word swap is still used in common commands such as vmstat and sar. To ensure you are not tackled by an operating system administrator, always use the term pages swapped (which is essentially just like a page getting paged out), instead of a process being swapped out, process swapping, or even just swapping. I typically say, "pages being swapped out" so I can move on. If you still get hassled, ask the aggressor to check the manual page on either vmstat or sar, and he will see it says something like the Red Hat Linux vmstat manual page: "Total number of swap pages the system brought out." Maybe it's not too informative, but that's what it says.

Personally, I prefer to use the page scans, as that avoids the entire swapping discussion. Operating system administrators feel more comfortable talking in terms of page scans and memory pressure.

I don't flat out say that there is a memory bottleneck. I always say that it looks like Oracle is consuming a lot of memory, a point an administrator will never argue. I'll ask if the administrator feels there is a lot of memory pressure being placed on the system-perhaps even too much for the current memory capacity. When I put the situation in those terms, a very productive memory-related discussion occurs.
