Usually see this when trying to start an instance and you have not enuf memory or your memory offset is not such that you can run a large SGA.

Hit this often on a new SUN that shmmax had not been set properly and we had not modified oracle for larger memory segments....

That is a good link Paul.

ORA-27101: shared memory realm does not exist

    Cause: Unable to locate shared memory realm     Action: Verify that the realm is accessible

What does this means? What do they mean by realm? How to see that whether it is accessible or not?
