Oracle Database Discussions

Hi all,

I'm trying to connect from Oracle 11g to PostgresSQL database using hs and db-link.
When I execute queries (select * from temp@postgres) I get error "FATAL: password authentication failed for user "user"[Microsoft][ODBC Driver Manager] Invalid connection string attribute".
I'm absolutely sure that user and password are right and I notice that Postgres database receive and empty password.

Also tnsping works.

This is my configuration:

Oracle 11g on Windows 2003 Server;

initPostgres.ora:

HS_FDS_CONNECT_INFO = postgres
HS_FDS_TRACE_LEVEL = 4

listener.ora

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = server-oracle)(PORT = 1521))
)
)

SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=postgres)
(ORACLE_HOME=D:\app\Administrator\product\11.1.0\db_1)
(PROGRAM=dg4odbc)
)
)

tnsnames.ora

# Connection to Postgres DSN

(HS=OK)
