Good day,
Does anyone have any experience in increasing the amount of shared memory
buffers available to Mac OS X/Darwin? When starting with more than 128
backend connections on a test G3 I encounter:
-----------------------------------------------------------------------------------
IpcMemoryCreate: shmget(key=5432001, size=33357824, 03600) failed: Invalid argument
This error usually means that PostgreSQL's request for a shared memory
segment exceeded your kernel's SHMMAX parameter. You can either
reduce the request size or reconfigure the kernel with larger SHMMAX.
-----------------------------------------------------------------------------------
However, I can find no helpful information looking around for how Darwin
handles this configuration. Hopefully it does not require a recompile of
the Kernel. ;)
Any knowledge on this topic would be greatly appreciated.
Best Regards,
Jw.
