Thread: IpcMemoryCreate: shmget failed (Permission denied)
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.

I don't know what you are expecting to find in /tmp. My example RH PostgreSQL install has nothing there either. Were you thinking of the postmaster.pid file? On my system, that is in the $PGDATA directory, i.e. /home/pgsql/data. Assuming that "ps" shows no active postmaster process, just delete the postmaster.pid file and try "ipcclean" again. Then try to start the postmaster again. You may want to try using "pg_ctl" to start and stop the postmaster, that is what it is designed for. "man pg_ctl" will tell you what you need to know. > > On Fri, 6 Jun 2003 16:34:31 -0700 (PDT) Jeff > Eckermann > (jeff_eckermann@yahoo.com) wrote: > > >Try running "ipcclean".
