Обсуждение: IPC Problems - URGENT !
Hi all
I am in a fix right now - i have been trying to install Postgres
6.4.2 on Linux ( Calderra Open Linux).
Everything goes on fine - i.e. configure,installation etc.
At the time of starting of the Postmaster ( postmaster -S -D 'Data
Directory'), I get the following error :
IPCMemoryCreate : shmget (identifies removed) Key=5432010
size=24588, permission =700 .
IPCMemoryAttach : shmget (identifies removed) Key=5432010
size=24588, permission =0 .
IPCMemoryCreate : shmat failed (invalid argument) id=2 .
FATAL 1 : AttachSLockMemory : could not attach segment .
It will be really very kind of you if you could help me out.
Thanks in advance
Thyaga
Did you build the kernel with IPC enabled?

I am in a similar position to the person below. I am trying to install
Postgres 6.5beta3 on a Solaris 7 machine (64-bit libraries installed) using
egcs-1.1.2 and receive the following when trying to run the 'postmaster -i'
command:
IpcMemoryCreate: shmget failed (Invalid argument) key=5432001,
size=1073152, permission=600
FATAL 1: ShmemCreate: cannot create region
Does anyone have some pointers on how to fix this? Or any idea what the
problem is? Thanks in advance,
Tony

On a related note, Postgres 6.4.2 appears to function perfectly (I just downloaded and installed, and haven't run into any problems yet).

Okay, this one I can help with a bit better...
If I remember correctly, this one is hitting you:
-B n_buffers
n_buffers is the number of shared-memory buffers for
the postmaster to allocate and manage for the backend
server processes that it starts. This value defaults
to 64 buffers, where each buffer is 8k bytes (or
whatever BLCKSZ is set to in config.h).
For starting up postmaster, the default is 64 buffers...try setting -B to
32 and see if htat helps...
