Well, am I at least correct in that it looks like you resolved it? That is you posting the solution over in the ITRC, right?

This problem had been resolved by decreased the shmmax in the /etc/ sysconfigtab file and added inet section in the sysconfigtab as well. I am not sure which one makes that work, by decreasing the shmax or the inet or the both.
Does anyone got any suggestion?

thanksP

If I were you, I'd simply back one of the changes out, test it, and then you may have a better idea. If it's a parameter issue, I will say that it's been my experience (not to be wise) that the Oracle manuals NORMALLY detail this information for a given platform pretty well. You may want to go back and skim through that information because there could very well be other parameters that could give you a problem later on.
