PostgreSQL on FreeBSD 7.0 amd64 with more than 2GB shared memory
Hi,
I'm trying to run PostgreSQL 8.3 on a FreeBSD 7.0 amd64 server with more
than 2GB shared memory. The machine has 32GB RAM installed.
After setting kern.ipc.shmmax and kern.ipc.shmall to the appropriate
values, I still had no chance to start postgres with more than 2GB of
shared memory.
I wrote a small test which does the same as postgres: shmget and shmat:
#include sys/ipc.h
#include sys/shm.h
#include stdio.h
#include errno.h
int main()
{
int shmid, memKey = 1;
void *memAddress;
unsigned long size = 2147483648UL;
shmid = shmget(memKey, size, IPC_CREAT | IPC_EXCL);
if (shmid 0) {
printf(shmget failed: %d\n, errno);
return 1;
}
memAddress = shmat(shmid, NULL, 0);
if (memAddress == (void *) -1) {
printf(shmat failed: %d\n, errno);
}
return 0;
}
I found out that shmget failed with ENOMEM in shmget_allocate_segment
(sysv_shm.c) because of an overflow of size (requested shared memory in
bytes):
int i, segnum, shmid, size;
...
size = round_page(uap-size);
if (shm_committed + btoc(size) shminfo.shmall) {
return (ENOMEM);
}
When changing size to an unsigned long shmget works - but now shmat then
fails again with ENOMEM.
Is there any easy way to use a shared memory segment which is larger
than 2GB?
Kind regards,
Robert
