Boa tarde pessoal!
Tenho um VPS, CentOS 5.5, com 1,5 GB de RAM e Postgresql 8.4
alterei "shared_buffer" de 32MB para "368MB" e o mesmo nao quer mais
iniciar.
Veja o Log:
# tail /var/lib/pgsql/pgstartup.log
---------------------
FATAL: could not create shared memory segment: Invalid argument
DETAIL: Failed system call was shmget(key=5432001, size=395280384, 03600).
HINT: 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. To
reduce the request size (currently 395280384 bytes), reduce PostgreSQL's
shared_buffers parameter (currently 47104) and/or its max_connections
parameter (currently 103).
If the request size is already small, it's possible that it is less
than your kernel's SHMMIN parameter, in which case raising the request size
or reconfiguring SHMMIN is called for.
The PostgreSQL documentation contains more information about shared
memory configuration.
