RE: solaris - semaphores - how ?

In addition, check the semaphores/shared memory segments on your system prior to starting oracle..

IPCS will show semaphores, shared memory and message queues... If you see some owned by oracle and DO NOT have an instance running on that machine-they can be removed as follows:
 ipcrm [ -m shmid ] [ -q msqid ] [ -s semid ]

I have seen where an instance crash will leave some semaphores remaining.. And if the parms in /etc/system are not set high enough-you wil get the error you have described...

Hope this helps...
Greg

Hi Rahul

Modify /etc/system and reboot the box

for example

set semsys:seminfo_semmns=200
set semsys:seminfo_semmni=70
set semsys:seminfo_semmsl=200
