[MMacun]

I have problem whith AIX 4.3.3 2GB RAM.

It runs Lotus domino server.
vmtune: current values:

PTA balance threshold percentage = 50.0%

number of valid memory pages = 524277 maxperm=50.0% of real memory
maximum pinable=80.0% of real memory minperm=10.0% of real memory
number of file memory pages = 261949 numperm=50.0% of real memory

number of compressed memory pages = 0 compressed=0.0% of real memory
number of client memory pages = 0 numclient=0.0% of real memory
# of remote pgs sched-pageout = 0 maxclient=10.0% of real memory


i allways run out of free pages.

From the output you provided it simply looks like you need to add more RAM to the system.

Also,

prior to adding more memory - can try decreasing the value of "maxperm=50.0% to ,say,30%.

I frequently "tune" maxperm and minperm. By reducing Maxperm - you free up memory that would ordinarily be used for caching and increasing minperm adds the memory made available by reducing Maxperm to memory available for indicual users. vmtune -P60 -p40
