Estimado Roberto,

Tu solucion va a depender del OS y version de Oracle. Por ejemplo:

Linux:

Puedes dispararlo desde el Crontab.

Windows:

Puedes dispararlo desde el Windows Scheduler.

Desde Oracle:

Usando el Oracle Scheduler, si usas version 10g o 11g, puedes crear el backup por export en forma de job desde el DB Console (OEM).

Si no sabes como hacerlo, avisame y te mandare algunos links para ayudarte, pero necesitare que me digas tu OS y version de Oracle.

Saludos,

Francisco Munoz Alvarez

Hola, gracias Francisco por su respuesta, mi SO es Windows XP Professional y mi SGBD es Oracle XE.

Saludos.

Estimado Francisco, he creado un Job con éxito, pero falla al ser ejecutado, por ejemplo, si consulto las vistas:

SELECT * FROM dba_scheduler_jobs WHERE job_name = ‘FULLEXPJOBXE’;
SELECT * FROM dba_scheduler_job_log WHERE job_name = ‘FULLEXPJOBXE’;

los resultados son:
