I've just migrated a bunch of applications from Solaris 8, running on
individual machines, to Solaris 10 running in multiple zones on AMD 64
(x4200) hardware. The current targets are running:
SunOS xxxxx 5.10 Generic_118855-15 i86pc i386 i86pc
In the Solaris 8 environment we had the following defined in /etc/system:
set rlim_fd_max=65536
set rlim_fd_cur=16384
IOW, the production Java processes use a lot of file descriptors. On the
new AMD64 machines, ulimit -a shows:
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 10240
coredump(blocks) unlimited
nofiles(descriptors) 1000
vmemory(kbytes) unlimited
and the following program:
#include <stdio.h>
#include <sys/resource.h>
main()
{
struct rlimit rlimit;
if (getrlimit(RLIMIT_NOFILE, &rlimit) == -1) {
perror("getrlimit fails");
exit(1);
}
printf("File soft limit: %d\n", rlimit.rlim_cur);
printf("File hard limit: %d\n", rlimit.rlim_max);
}
when run, will indicate:
File soft limit: 1000
File hard limit: 1000
Where is this "1000" number defined?
How can I set the default max open file descriptors to something like 12k?
I can't make sense of the results I get on a box with:
SunOS xxx 5.10 Generic_118855-19 i86pc i386 i86pc
after trying various values in /etc/system, both for the global zone, and
in other non-global zones for:
rlim_fd_max
rlim_fd_cur
Obviously I'm missing something obvious - but, believe me, I've put
considerable time in using google.com and docs.sun.com. Perhaps I don't
know the "secret handshake"?
Any help appreciated.
