LIBTUX_CAT:681Failure ro create message queue

Question

Hi,
We get this error when we start more than 3 Appserver.
(Solaris 8 + Oracle)
Any information would be appreciated. Thanks.
It's my /etc/system file...
set maxusers=80
set shmsys:shminfo_shmmax=8589934590
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=15

And just to add to $0.02,
Oracle doesn't use message queues, only shared memory and semaphores. Here is the
/etc/system I use on my Solaris 7 system for development work:
* IPC Tunables - Shared memory
* max shared memory segment size (SHMMAX)
set shmsys:shminfo_shmmax=4294967295
* min shared memory segment size (SHMMIN)
set shmsys:shminfo_shmmin=1
* max attached shm segments per process (SHMSEG)
set shmsys:shminfo_shmseg=100
* shared memory identifiers (SHMMNI)
set shmsys:shminfo_shmmni=100
* IPC Tunables - Semaphores
* semaphores in system (SEMMNS)
set semsys:seminfo_semmns=4096
* semaphore identifiers (SEMMNI)
set semsys:seminfo_semmni=128
* entries in semaphore map (SEMMAP)
set semsys:seminfo_semmap=4096
* undo structures in system (SEMMNU)
set semsys:seminfo_semmnu=4096
* max semaphores per id (SEMMSL)
set semsys:seminfo_semmsl=2048
* max operations per semop call (SEMOPM)
set semsys:seminfo_semopm=256
* max undo entries per process (SEMUME)
set semsys:seminfo_semume=1024
* semaphore maximum value (SEMVMX)
set semsys:seminfo_semvmx=32767
* IPC Tunables - Messages - For Tuxedo
* entries in msg map (MSGMAP)
* set msgsys:msginfo_msgmap=2048
* max message size (MSGMAX)
* set msgsys:msginfo_msgmax=262144
* max bytes on queue (MSGMNB)
* set msgsys:msginfo_msgmnb=262144
* message queue identifiers (MSGMNI)
* set msgsys:msginfo_msgmni=1024
* message segment size (MSGSSZ)
* set msgsys:msginfo_msgssz=1024
* system message headers (MSGTQL)
* set msgsys:msginfo_msgtql=2048

Fabrice:
The error implies that msgmni is set too low. msgmni is the total number of message
queues allowed in the system. Getting an error here implies that oracle or some
other process is consuming them.
For Tuxedo Classes we use the listed values as minimum for the kernel parameters
to perform the labs. In these classes the machine is only running Tuxedo. This
means the values are probably lower than those required by a production system or
one hosting Oracle as well as Tuxedo.
Message Queue Parameters:
MSGMAP 800
MSGMAX 32769
MSGMNB 42000
MSGMNI 400
MSGSSZ 64
MSGTQL 400
MSGSEG 2048
Semaphore Parameters:
SEMMAP 800
SEMMNI 800
SEMMNS 800
SEMMNU 800
SEMMSL 800
SEMOPM 64
SEMUME 64
SEMVMX 32769
SEMAEM 16384
Shared Memory Parameters:
SHMMAX 2097152
SHMMIN 1
SHMMNI 100
SHMSEG 64
SHMALL 2048
**Note: Some UNIX kernels do not support all of the above parameters or have additional
parameters not listed.
Hope this helps!
