RE: ORA-27101: shared memory realm does not exist

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?
