At HP-UX 10.20 you can call "/usr/sbin/sysdef", it will list a table including
the maxdsiz setting (and it's min and max value). It should be simple to
extract the info:
serv01 160: /usr/sbin/sysdef
NAME VALUE BOOT MIN-MAX UNITS FLAGS
....
maxdsiz 163840 - 256-655360 Pages -
maxssiz 16384 - 256-655360 Pages -
....
Pagesize is 4kb on this system. I don't have HP-UX 11 to crosscheck, whether
it will yield the same table.
As was found out in the old thread, a minimum value of 128MB is necessary
(maybe a bit less is enough but 128MB is known to work).
This however does not solve the problem I described. I do have 163840*4kB
available, giving 640MB altogether and it still does not work. Top shows
that the 640MB are never used, so there is no memory limit here (I have 64MB
stack limit instead of the 8MB default, so I was also generous here).
My net result as of now: +O3 and +O4 do not work on HP-UX 10.20 (and probably
with 11.0) as of the latest snapshots, even with tons of memory.
Best regards,
Lutz
