No RTFM please, if you have passion, read this:
I have Solaris 8 installed with 1GB of RAM, 3GB of swap space, 4 disc of size 36GB each and mirrored under solsuite disk suite. My /etc/system file has typical sharedMemSegment+semaphore from Oracle manual, which is perfectly working on other m/c with same database configuration but w/o disc mirroring, as listed below.
set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=10
set semsys:seminfo_semmni=100
set semsys:seminfo_semmsl=200
set semsys:seminfo_semmns=300
set semsys:seminfo_semopm=100
set semsys:seminfo_semvmx=32767
During DB creation, oracle fails with
ORA-27102: out of memory
SVR4 Error: 22: Invalid argument
messages.
* Trace file does not reveal anything but the fact that it could not claim shared memory of 128MB with following message.

So what is wrong?

Thanks for your attempt.
Yes, I had already did everything you mentioned in your email, just forgot to put it in my original post - it was lengthy anyway!
Besides, here is the reason why all went wrong in first place! - it is interesting to learn.
In fact our SA found out the the machine had some issues with mirroring! Solstice suite was reporting that one of the mirrored disk was in critical condition! - so that's why is was not reading /etc/system file, fix mirrors first! -
He fixed it, restarted the box and everything was fine.
-Thanks again,
DP.
