When trying to start the postmaster after installation, I get this
error :
$ postmaster -D /usr/local/pgsql/data
IpcMemoryCreate: shmget failed (Permission denied) key=5432001,
size=1104896, permission=600
This type of error is usually caused by an improper
shared memory or System V IPC semaphore configuration.
For more information, see the FAQ and platform-specific
FAQ's in the source directory pgsql/doc or on our
web site at http://www.postgresql.org.
FATAL 1: ShmemCreate: cannot create region
Checking the share memory status:
$ ipcs -l
------ Shared Memory Limits --------
max number of segments = 1024
max seg size (kbytes) = 32768
max total shared memory (kbytes) = 134217728
min seg size (bytes) = 1
Cgecking the shmmax configuration value :
$ vi /proc/sys/kernel/shmmax
33554432
Check hard disk space :
$ df -vk
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda6 4719972 4407656 72548 99% /
/dev/hda1 69973 2476 63884 4% /boot
I can not access the postrgresql mail list archives or subscribe to a
list due to the hard disk failures they had encountered recently.
I'm working on a Redhat Linux 7.0 (Guinness)
Kernel 2.2.16-22 on an i686
with the latest PostgreSQL version 7.3.3
The machine has 128mb ram with a 4gb hard drive
PS. I am not a Linux expert and have to get this working on my own so
any help would be appreciated.
Thanks
Theuns
