SOS Swap Summary
The Swap Summary Screen
The Swap Summary screen displays information on system swap space utilization. Swap space
is used for paging and deactivating. (As of HP-UX 10.0, swapping has been replaced with
process deactivating, however, the space used for paging/deactivating is still called "swap space"
for historical reasons.)
