vm and buffer cache
i have a serious doubht about the assignment of memory
in hp-ux system .
i read from somewhere that the page allocation in
hp-ux is not unified unlike compaq .
i wanted to know in hp-ux kernel ,once the pages are
assigned for the univarsal buffer cache ,can those pages
be used by the virtual memory system .
Are the total virtual memory pages noway related to
buff-cache pages . can their respective counts be treated as seperate assignmemt of pages .
anybody clarifies i will be thankfull .

Try the vmstat command. vmstat -s will show you quite a bit about your system. Do a man on vmstat to find out more.

Regarding your philsophical differences about HPUX paging methods, I am sure that they have worked out whatever you may percieve as problems with their method of paging.

If you would go to HP's very good site. www.itrc.hp.com It is a forum they have setup to answer all types of questions.

I am sure that you would find the answer there.
