HP-UX 11.23 has no filecache, you need to look at "buf cache".

I am not able to make out what are you looking for is its physical memory or active process in memory or buffer cache.

If you want to view available and consume memory you can use glance,top,swapinfo

$ /usr/sbin/swapinfo -tam
Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 8192 0 8192 0% 0 - 1 /dev/vg00/lvol2
dev 16000 0 16000 0% 0 - 1 /dev/vg00/swap
dev 50000 0 50000 0% 0 - 1 /dev/vg01/swap1
dev 50176 0 50176 0% 0 - 1 /dev/vg02/swap2
reserve - 58935 -58935
memory 50583 10909 39674 22%
total 174951 69844 105107 40% - 0 -

The output shows the amount of memory available,free,consumed in MB

You can also view buffer through
# sar -b 3 5
