Temario
PRESENTACIÓN:
Este curso profundiza en dos de las tareas más importantes de un administrador de bases de datos: las copias de seguridad y la recuperación de datos. Por ello, se cubren con sumo detalle los conceptos y la arquitectura que dan soporte a dichas actividades, así como los pasos para llevarlas a cabo de diferentes maneras y en diversas situaciones. Ello incluye cómo definir y evaluar nuestros propios escenarios para hacer copias de seguridad y la recuperación de datos.
Asimismo, los asistentes aprenderán a gestionar la memoria de forma efectiva y a realizar evaluaciones de rendimiento y tareas de optimización mediante las herramientas advisors. Por último, también se cubrirán todos los tipos de tecnologías Flashback, de programación de tareas dentro y fuera de la base de datos, y de control del uso de recursos del sistema.
Este curso prepara para el examen 1Z0-053: Oracle Database 11g: Administration II conducente a la certificación Oracle Database 11g Administrator Certified Professional (Oracle 11g DBA OCP).
OBJETIVOS:
Realizar copias de seguridad y recuperación de una base de datos (y de sus partes) con RMAN. Utilizar la tecnología flashback para visualizar estados anteriores de los datos, y revertir ya sea objetos ya sea la base de datos completa a un estado anterior. Utilizar una configuraciò,n de memoria adecuada y flexible en la base de datos. Identificar sesiones excesivas de bases de datos, así como un rendimiento insuficiente de SQL. Configurar la base de datos Oracle para una recuperación óptima. Configurar la instancia de la base de datos de manera que los recursos estén adecuadamente asignados entre sesiones y tareas. Programar tareas para su ejecución dentro y fuera de la base de datos. Utilizar la compresión para optimizar el almacenamiento de la base de datos y duplicar una base de datos
