Increase memory for shared memory

Question

Hi there!

Actually when trying to get shared memory, shmget() often fails with because being unable to allocate memory. The physical size of RAM really shouldn't be the problem (4GB is enough, I think). Rather there's probably anywhere in the systems properties a limit for allocating shared memory set. Does anyone know, where I can find this property?

Edit: I'm using Mac OS X Version 10.6

Best regards,
Niels

Depends on the OS. PostgreSQL documentation has tips for changing the shared memory limit on various platforms.
