La placa base contiene componentes clave como el zócalo CPU, ranuras de memoria RAM, chipset, BIOS y conectores para tarjetas de expansión y almacenamiento. Conecta todos los componentes del ordenador y permite la comunicación entre ellos a través del chipset.

Introduced in Oracle Database 12c, the new MATCH_RECOGNIZE clause allows pattern matching across rows and is often associated with Big Data, complex event processing, etc. Should SQL developers who are not (yet) faced with such tasks ignore it? No way! The new feature is powerful enough to simplify a lot of day-to-day tasks and to solve them in a new, simple and efficient way. The insight into a new syntax is given based on common examples, as finding gaps, merging temporal intervals or grouping on fuzzy criteria. Providing more straightforward approach for solving known problems, the new functionality is worth to be a part of every developer’s toolbox.

Maximum Availability Architecture - Best Practices for Oracle Database 19cGlen Hawkins
Provides the latest updates on high availability (HA) best practices in this well-established technical deep-dive session. Learn how to optimize all aspects of Oracle Active Data Guard 19c. See how to use session draining, transparent application continuity, Oracle RAC, and Oracle GoldenGate to mask outages and planned maintenance from users and to accelerate time to repair for single database or your fleet of databases. Hear about the latest HA best practices with Oracle Multitenant and understand how the new sharded architecture can achieve even higher levels of HA and fault isolation for OLTP applications. Find out how everything you know about Oracle Maximum Availability Architecture (MAA) on-premises can be deployed in the cloud.
This Presentation is about Oracle Database.
In Oracle Database we have different types of Languages.
In This Presentation We have discussed Data Manipulation Language, Data Defination Language and Data Control Language In the Oracle.
How to Use Oracle RAC in a Cloud? - A Support QuestionMarkus Michalewicz
This presentation, which was first presented during Sangam16, discusses general and specific support rules for the Oracle Database and Oracle RAC with the purpose of enabling you to determine whether a given system is supported, certified or even recommended. This presentation was last updated on August 31st 2017 (minor update).
Troubleshooting Tips and Tricks for Database 19c - EMEA Tour Oct 2019Sandesh Rao

Part1 of SQL Tuning Workshop - Understanding the OptimizerMaria Colgan
Part 1 of a 5 part SQL Tuning workshop, This presentation covers the history of the Oracle Optimizer and explains the first thing the Optimizer does when it receives a SQL statements, which is to transform the SQL statement in order to open up additional access paths.
Before version 9i of the Oracle database, more and more Oracle components stored their tables in the SYSTEM tablespace. This lead to a high space consumption in this important tablespace. In Oracle database 10g introduced the SYSAUX tablespace and moved everything which is not part of the data dictionary from the SYSTEM tablespace to SYSAUX. Since then, more and more database components populate the SYSAUX tablespace and it keeps growing ... - and if the DBA is not careful, the tablespace SYSAUX tablespace can become really huge
The presentation shows how to analyze and reduce the occupancy of the SYSAUX tablespace and how to avoid it in advance by suitable settings.
Paper: Oracle RAC Internals - The Cache Fusion EditionMarkus Michalewicz
Accompanying paper to the presentation with the same name (see other slideshares). This paper explains some of the inner workings of Oracle RAC and the Oracle Cache Fusion technology, explaining how Oracle RAC can ensure horizontal scaling across up to the supported number of nodes in a cluster.
Harnessing the Power of Optimizer HintsMaria Colgan
The goal of the Oracle Optimizer is to examine all possible execution plans for a SQL statement and to pick the one with the lowest cost, which should be the most efficient. From time to time, it may become necessary to influence the plan the Optimizer chooses. The most powerful way to alter the plan chosen is via Optimizer hints. But knowing when and how to use Optimizer hints correctly is somewhat of a dark art. This session explains in detail how Optimizer hints are interpreted, when they should be used, and why they sometimes appear to be ignored.

3. INTRODUCCION Y COMPONENTES DE LA
PLACA BASE
Es una tarjeta de circuito impreso a la que se conectan las demás partes
del ordenador.
Los principales componentes son: zócalo de CPU, conectores de
alimentacion, ranuras de memoria RAM, chipset, bios…
4. 1-.ZÓCALO CPU
Es un sistema electromecánico de soporte y conexión eléctrica, instalado
en la placa base, que se usa para fijar y conectar un microprocesador.
Existen variantes desde 40 conexiones para integrados
pequeños, hasta mas de 1300 para microprocesadores, los mecanismos
de retención del integrado y de conexión dependen de cada tipo de
zócalo, aunque en la actualidad predomina el uso de zócalo ZIF(pines o
LGA(contactos).
5. 2-.VÍAS(CHIPSET)
Chipset es el conjunto de circuitos integrados diseñados
con base a la arquitectura de un procesador(en algunos
casos diseñados como parte integral de esa
arquitecura), permitiendo que ese tipo de procesadores
funcionen en una placa base. Sirven de puente de
comunicación con el resto de componentes de la placa.
6. 3-.CACHÉ
Un caché es un sistema especial de almacenamiento de alta
velocidad. Puede ser tanto un área reservada de la
memoria principal como un dispositivo de
almacenamiento de alta velocidad independiente. Hay
dos tipos de caché frecuentemente usados en las
computadoras personales. Memoria caché y caché de
disco.
7. 4-.RANURAS DE MEMORIA RAM
Las ranuras de memoria RAM son los conectores en los cuales se
conectan los módulos de memoria principal del ordenador. A
estos conectores también se les denomina bancos de memoria.
La memoria de acceso aleatorio(en inglés RAM) es la memoria
desde donde el procesador recibe las instrucciones y guarda
los resultados.
8. 5-.PCI SLOTS
Un Peripheral Component Interconnect(PCI) consiste en un
bus de ordenador estándar para conectar dispositivos
periféricos directamente a su placa base. Estos
dispositivos pueden ser circuitos integrados ajustados
en esta otarjetas de expansion que se ajustan en
conectores.
10. 7-.BATERÍA
Se encarga de mantener la alimentación eléctrica del reloj de
tiempo real(RTC), tambien es la encargada de mantener os
parámetros almacenados en la CMOS RAM que son usados por
la BIOS.
La duracion de esta bateria suele rondar entre los 3 y los 5
años, cuando el sistema detecta que la batería esta baja de carga o
agotada nos muestra un mensaje al arrancar el ordenador.
11. 8-.BÍOS
El BIOS es un firmware que se ejecuta al encender la computadora
y que localiza y reconoce todos los dispositivos necesarios
para cargar el sistema operativo en la memoria RAM, es un
software muy básico instalado en la placa base que permite
que ésta cumpla su cometido. Porporciona la comunicación de
bajo nivel, el funcionamiento y configuración del hardware del
sistema que, como mínimo, maneja el teclado y proporciona
una salida básica(emitiendo pitidos normalizados por el altavoz
de la computadora si se producen fallos) durante el arranque.
12. 9-.CONECTORES IDE Y EIDE
Los conectores IDE para conectar dispositivos de
almacenamiento, tales como discos duros, unidades de estado
sólido y lectores ópticos.
EIDE es una extensión del iriginalmente IDE, es la denominacion
que recibe la interfaz más empleada actualmente en los PC
domésticos y cada vez más en aquellos ordenadores de altas
prestaciones para la conexión de discos duros.
13. 10-.RANURA CNR
CNR es una ranura de expansión en la placa base para dispositivos de
comunicaciones como módems, tarjetas LAN o USB, al igual que la
ranura AMR también es utilizada para dispositivos de audio.
14. 11-.RANURA AGP
AGP es un puerto(puerto que sólo se puede conectar un
dispositivo, mientras que en el bus se pueden conectar varios)
desarrollado en 1996 como solución a los cuellos de botella que
se producían en las tarjetas gráficas que usaban el bus PCI. El
diseño parte de las especificaciones PCI 2.1.
