Hi - I'm an Oracle newbie having just installed it on my winxp box for a university project. I've been trying for some time now to connect to it using sql+ but haven't been able to do so. I think I've got my tnsnames.ora file configured correctly:

SIMONDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.162)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = Oracle)
)
)

I'd like to be able to connect using the service name "Oracle", but it just doesn't seem to work! Any help would be much appreciated!
