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).  Thanks
again for any help,

Tony

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...

Using ipcs to list shared resources, ipcrm to remove one.  The id is the
number listed under shmid by ipcs.
