Open TNSNAMES.ora

Add
--------------------------------
STAGING =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = STAG)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = STAGING)
)
)

---------------------------------------
SERVICE_NAME = STAGING

STAGING is the database name .look db_name in init.ora on database server

HOST = STAG

STAG is your database machine name .

Now connect using username/password@staging
