If 'nan' means "not a number," then what does 'q' or 'Q' mean?

nan means "not a number", inf (afaik) = infinitive
you should check if your vmtune is correct for you os/kernelversion

Subject: Vmtune question. What is NaNQ% ?
I am trying to change a few of the tuning parameters on our AIX5.1 ML3
p660 running in 64bit mode for the dba. When I view the current settings
using vmtune (and/or vmtune64), I see a value for numclient as NaNQ%.
What does this mean?
number of valid memory pages = 3145712 maxperm=INF% of real memory
maximum pinable=80.0% of real memory minperm=INF% of real memory
number of file memory pages = 0 numperm=NaNQ% of real memory
number of compressed memory pages = 11127 compressed=INF% of real
memory
number of client memory pages = 0 numclient=NaNQ% of real memory
# of remote pgs sched-pageout = 0 maxclient=INF% of real memory
When I try to change the settings for maxclient using vmtune, it also
goes into a NaNQ%. If I then try to change the maxperm and minperm, they
go into a NaNQ% and the system hangs and requires a hard reboot. The dba
recomended the settings for minperm=2% and maxperm=3%. This box is
running the database only and no other applications.
