Lyall, Do you have the ORACLE_SID environmental declared before you start SqlPlus?

Have had the same core dump ever time i try to startup nomount. I've look through posts, lists, different DBA areas on the net and i think the problem is in the pfile. i get ora-600: internal error code arguments [keltnfy-lmdInit] [46], [], [], [] and then in the stack trace: ora-12707: shared memory realm does not exit. Linux error: 2: No such file or directory. It sounds like posts i've seen are correct for me, that an environment variable is not set correctly. but i haven't been able to find any miss types. I remember ANYSQL on the list saying that there is a patch coming out for 10g soon. I want to know if anyone could give me some suggestions. I can provide more info if needed.
