Well, I tried to install Oracle 9i EE on Red Hat Linux 7.2, and the installation worked fine. I choosed to install only the software without the database.
At the end I tried to manually create the database, and I got troubles.
%lsnrctl start ---ok
%sqlplus - nolog
SQL > connect / as sysdba --ok
SQL > startup nomount --oops
ORA - 03113 - end-of-file on communication channel

I tried to modify tnsnames.ora, listener.ora, sqlnet.ora but with no results.

$ORACLE_SID=TEST

I Tried to modify like this
========================
listener.ora
=============
LSNRTEST =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = DANIEL)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = TEST))
)
)

tnsnames.ora
=============
TEST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = DANIEL)(PORT = 1521))
(CONNECT_DATA =
(SID = TEST)
(SRVR = DEDICATED)
)
)

========== ... but no results

I'll be grateful for some insighs on this problem...

Thanks a lot !

Best regards
