Setting up a role and linking it to an user is not working as expected in SQL

I created a role R_CLIENTE:

CREATE ROLE R_CLIENTE IDENTIFIED BY RolCliente;

Then I granted some privileges on it:

GRANT SELECT ON alquiler.CLIENTE TO R_CLIENTE;

(Schema alquiler and table CLIENTE already exist). Then I created an user U_Cliente1:

CREATE USER U_Cliente1 IDENTIFIED BY Cliente1 DEFAULT TABLESPACE table_def TEMPORARY TABLESPACE table_temp QUOTA 2M ON table_def PASSWORD EXPIRE;

(Both tablespaces already exist). I granted U_Cliente1 to R_CLIENTE privileges:

GRANT R_CLIENTE TO U_Cliente1;

When I login as U_Cliente1 I am not able to select any data from the table alquiler.CLIENTE:

SQL> desc alquiler.CLIENTE;
ERROR:
ORA-04043: object alquiler.CLIENTE does not exist

However, if I grant directly the privilege to the user U_Cliente1:

GRANT SELECT ON alquiler.CLIENTE TO U_Cliente1;

Now I am able to select the table alquiler.CLIENTE:

SQL> desc alquiler.CLIENTE;
 Name                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 K_CODCLIENTE                  NOT NULL NUMBER(5)
 N_NOMBRE1                 NOT NULL VARCHAR2(15)
 N_NOMBRE2                      VARCHAR2(15)
 N_APELLIDO1                   NOT NULL VARCHAR2(15)
 N_APELLIDO2                        VARCHAR2(15)
 N_DIRECCION                   NOT NULL VARCHAR2(50)
 Q_TELEFONO                NOT NULL NUMBER(10)
 K_CODREF                       NUMBER(5)
 I_TIPOID                  NOT NULL VARCHAR2(2)
 Q_IDENTIFICACION              NOT NULL VARCHAR2(10)

How can I properly link a role and user(s) so they can all share the same privileges?

The reason that the direct grant worked the way it did is because direct grants are always active. Roles can be activated and deactivated within a session. In your example you didn't configure the role as a default role, so it must be explicitly activated after you login, like this:

set role r_cliente;

alternatively, after granting the role set it as a default for the user:

alter user U_Cliente1 default role r_cliente;

or

alter user U_Cliente1 default role all;

Then the role will be active automatically when you login.
