and while trying to initialize shared memory through onmonitor

I am getting error

operating system error -9
unable to write to $INFIRMIXDIR/etc

I have given ROOTPATH as /ppc/rootdbs with user informix , group informix and permissions 660

what might be the problem please help...

Thank you in advance...

Hello,

Create a filesystem (call it IFXDUMP or anything you want) and the owner of this FS should be informix:informix. Modify your onconfig's DUMPDIR entry to point to this FS.

Also modify the shared memory parameters, eg as below

SHMVIRTSIZE 100000 # initial virtual shared memory segment size
SHMADD 8192 # Size of new shared memory segments (Kbytes)
SHMTOTAL 0 # Total shared memory (Kbytes). 0=>unlimited


Try starting informix once again. If it failes, attach your onconfig file and also the informix message log file.

Nitin

Check your SQLHOSTS, probably the hostname what you specified don't exists on the /etc/hosts file or the port name don't exists on the /etc/services

Estoy instalando informix 10 en linux centos 5.0 y cuando ejecuto el comando oninit -ivy para inicializar la base de datos me arroja el siguiente error:
oninit: Fatal error in share mamory creation.
Al revisar en el online.log encuentro lo siguiente:

SHMGET:[EEXIST][17]:Key 525a4801: Share memory already exists
mt_shm_init: can`t create resident segment

quien me puede ayudar con esto?

before execute the oninit , execute a few times:
"onmode -ky"
if not work check if have any memory alocation with "ipcs".
or just reset the machine.
