Hi!
I installed postgresql-7.2.1 on Sun solaris 5.7 running on sparc processor.
while installing i had no problems but as soon as start with following line
/usr/local/pgsql/bin/postmaster -D /user2/pgsql/data or /usr/local/pgsql/bin/pg_ctl -D /user2/pgsql/data -l logfile start
kailas# /usr/local/pgsql/bin/postmaster -D /user2/pgsql/data
IpcMemoryCreate: shmget(key=5432001, size=1441792, 03600) failed: Invalid argument
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 1441792 bytes), reduce PostgreSQL's shared_buffers parameter (currently 64) and/or its max_connections parameter (currently 32).
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 Administrator's Guide contains more information about
shared memory configuration.
I am a new person with sun solaris so please sugest me in details i you can !
with regards
