hi,
so, i read all this stuff about using shared memory, preloading stuff to
each child doesn't have it's own copy. so i went ahead and compile sysV
shared memory into my kernel. however, ipcs tells me that nothing is
using shared memory:
server# ipcs -m
Shared Memory:
T ID KEY MODE OWNER GROUP
despite the fact that teh webserver is up and running:
server# usefulps | head -1 ; usefulps | grep httpd
%CPU %MEM NVCSW NIVCSW NSWAP VSZ RSS RSZ TSIZ PID PPID COMMAND
0.0 4.7 360 86 0 6016 4480 4480 312 6893 1 httpd
0.0 4.8 1 1 0 6016 4564 4564 312 6894 6893 httpd
0.0 4.8 1 0 0 6016 4564 4564 312 6895 6893 httpd

0.0 4.8 1 0 0 6016 4564 4564 312 6898 6893 httpd
This is my startup script:
use Apache::Registry();
use HTML::Embperl();
1;
Environment:
FreeBSD 3.2
Apache 1.3.9
mod_perl 1.21
So, am I totally missing something here? Does shared memory have to be
compiled into the kernel before I compile Apache? Does shared memory
mean something outside the context of sysV IPCS? Do I need semaphores and
messages as well, or is shared memory alone ok?
tia.
