Problema de conexión

Tengo dos maquinas virtuales ...

1. Un Linux 7 con una base de datos Oracle 12c con la siguiente configuracion ...

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = OracleDB)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) )

================================================================

SQLNET

================================================================

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

================================================================

TNSNAMES

================================================================

ORCL =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = OracleDB)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)))

================================================================

2. Por otro lado tengo otra VM en este caso con Windows 8.1 en el cual tengo instalado

un cliente 11gR2 con la siguiente configuración ...

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = OracleDB)(PORT = 1521)))

(DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))))

SID_LIST_LSN_LISTENER =

(SID_LIST =

(SID_DESC =

(ORACLE_HOME = C:\App\Oracle11gCliente\product\11.2.0\client_1)

(SID_NAME = ORCL)))

================================================================

TNSNAMES

================================================================

ORCL =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = OracleDB)(PORT = 1521)))

(CONNECT_DATA =

(SERVER = SHARED)

(SERVICE_NAME = ORCL)

(INSTANCE_NAME = ORCL)))

================================================================

Ahora bien, teniendo la base de datos online y el LISTENER activo, cuando quiero conectar desde Windows, el resultado es el siguiente ...

C:\>lsnrctl start

Iniciando tnslsnr: espere...

TNS-12560: TNS:error del adaptador de protocolo

TNS-00530: Error del adaptador de protocolo

C:\>tnsping ORCL

Archivos de parametros utilizados:

C:\App\Oracle11gCliente\product\11.2.0\client_1\NETWORK\ADMIN\sqlnet.ora

Adaptador TNSNAMES utilizado para resolver el alias

Intentando contactar con (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = OracleDB)(PORT = 1521))) (CONNECT_DATA = (SERVER = SHARED) (SERVICE_NAME = ORCL) (INSTANCE_NAME = ORCL)))

TNS-12541: TNS:no hay ningun listener

Otros detalles ...

- Tengo declaradas las variables TNS_ADMIN, ORACLE_SID y ORACLE_HOME.

- El servicio LISTENER OracleOraClient11g_home1TNSListener; no inica por el error 3 diciendo que

El sistema no puede encontrar la ruta especificada

NO SE EN DONDE MAS MIRAR !!!!
