Turns out someone previously had setup our systems for ingres and hadn't
documented it. Decidedly annoying.
The problem is semaphores are not turned on by default (at least on 2.3 SS10's)
so you have to forceload them in /etc/systems. I discovered this myself about
an hour after sending the above email so I managed to get it up and running.
The disks are now winging their way to Madrid on a Quantas flight.
Whilst semaphores _do_ auto load themselves when you actually use one, the
ingres startup scripts do an 'ipcs' and grok the output so if semaphores are
not forceloaded ingres dies complaining that no semaphores exists.
My /etc/system has in it:
* for ingres
forceload: sys/semsys
forceload: sys/shmsys
set semsys:seminfo_semmap=10
set semsys:seminfo_semmni=100
set semsys:seminfo_semmns=1000
set semsys:seminfo_semmnu=30
set semsys:seminfo_semmsl=50
set semsys:seminfo_semopm=10
set semsys:seminfo_semume=10
set semsys:seminfo_semusz=96
set semsys:seminfo_semvmx=32767
set semsys:seminfo_semaem=16384
set shmsys:shminfo_shmmax=10000000
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
This keeps ingres happy, me happy and my stress levels down. I think.
Cheers,
Mark
