Hi,
I have the following situation here:

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
tnsnames.ora

System is Debian Lenny.
I already tried it with the real hostname (c2aplathq001) in tnsnames.ora and listener.ora.
Help would be greatly appreciated :-)
Edit:
Oracle specific env variables:
LDPATH="/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib"
ORACLE_HOME="/usr/lib/oracle/xe/app/oracle/product/10.2.0/server"
ORACLE_SID="XE"
PATH="/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
TWO_TASK="XE"

Hi,
oracle@c2aplathq001:~$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.1.0 - Production on Wed Jul 8 14:27:54 2009

Connected to an idle instance.
SQL>
c2aplathq001:~# hostname
c2aplathq001
I'm fine with TWO_TASK not set if its not necessary.

Edit: You actually solved my problem :-)
Seem like it was no good idea to set TWO_TASK or ORACLE_SID before trying to install ORACLE.
I unset both variables purged the package reinstalled it and everything is up and running.
Thank You
