Trouble with DOA3.3

[glory]

When I try to connect to the remote database I've got a message "ORA-03121: no interface driver connected - function not performed"
Error initializing ORA73.DLL library.
oraSession->Preferences->UseOCI7 = true;
And when I call method
TOracleSession-->LogOn() I've got a message describes above.
My Oracle settings:
//==== tnsnames.ora ===//
mycomp.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Host = mycomp)
(Port = 1521)
)
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Host = mycomp)
(Port = 1526)
)
)
(CONNECT_DATA = (SID = ORCL)
)
)

What is the actual error message (Error initializing ORA73.DLL library or ORA-03121)?

ORA-03121 usually indicates that you are not specifying a database name in TOracleSession.LogonDatabase.
