Hello everybody.

I want to connect with Sqldeveloper and I have the error :

ORA-12514, TNS:listener does not currently know of service re

But with SQL*PLUS, I connect correctly.

I have Windows Vista.

My tsnames.ora is

# tnsnames.ora Network Configuration File: C:\app\HP_Propietario\product\11.2.0\dbhome_3\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.10.10)(PORT = 1521))


ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)

ORCL =
(DESCRIPTION =

)
)

ADR_BASE_LISTENER = C:\app\HP_Propietario


I write the host 10.10.10.10 because I have installed a loopback adapter with address 10.10.10.10

The information in SQLDeveloper is:

Conection Type: BASIC
Host Name: 10.10.10.10 (address of loopback adapter in file of windows hosts)
Port 1521
Service Name : orcl


Could somebody help me?

Thanks in advance
