ORA-01034 & ORA-27101: shared memory realm does not exist [message #54465]

I have Oracle 9i, running on RedHat 7.2. I have my environment variables (ORACLE_HOME, ORACLE_SID, NLS etc...) set during login for my user Oracle.

When I attempt to "sqlplus sue " I recieve the error:

ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory

However, when I attempt to "sqlplus sue@test " I connect no problem. Also, if I echo my $ORACLE_SID I do get the correct variable name (it matches my tnsnames.ora).

What am I missing here?

Thanks!!

1. is $ORACLE_HOME/bin included in your $PATH?
2. if TEST is the connect string, does that target
   database SID same as your ORACLE_SID?

this error append when Oracle is not stated .. but it's not ( in this case )

1-use tnsping [[DB]] to see if Ur database is local
host = ur machine if not connect to host...
2-verify that ORACLE_SID and ORACLE_HOME is correct
( like 0 ( zero )is not O ( o letter ) )
3-verify that all processes are started ( use ps -ef | grep [[DBNAME]] if not Ur database is not open.
