It's here! Oracle Database In-Memory is officially released

Oracle Database 12.1.0.2 was officially release today and is now available for download, which mean Oracle Database In-Memory is officially here!
Along with the software release comes a whole new set of collateral that explains in detail how all of the new Oracle Database In-Memory functionality works. The In-Memory page on Oracle.com has all of the juicy details including the official whitepaper.
Here is a quick look at the Introduction and the start of the paper. You can find the full paper here. Happy Reading!

Introduction 

Today’s information architecture is much more dynamic than it was just a few years ago. Business users now demand more decision-enabling information, sooner. In order to keep up with increases in demand, companies are being forced to run analytics on their operational systems, in addition to their data warehouses. This leads to a precarious balancing act between transactional workloads, subject to frequent inserts and updates, and reporting style queries that need to scan large amounts of data.

With the introduction of Oracle Database In-Memory, a single database can now efficiently support mixed workloads, delivering optimal performance for transactions while simultaneously supporting real-time analytics and reporting. This is possible due to a unique "dual-format" architecture that enables data to be maintained in both the existing Oracle row format, for OLTP operations, and a new purely in-memory column format, optimized for analytical processing. In-Memory also enables both datamarts and data warehouses to provide more ad-hoc analytics, giving end-users the ability to ask multiple business driving queries in the same time it takes to run just one now.

Embedding the in-memory column format into the existing Oracle Database software ensures that it is fully compatible with ALL existing features, and requires no changes in the application layer. Companies striving to become real-time enterprises can more easily achieve their goals, regardless of what applications they are running. This paper describes the main components of Oracle Database In-Memory and provides simple, reproducible examples to make it easy to get acquainted with them. It also outlines how Database In-Memory can be integrated into existing operational systems and data warehouse environments to improve both performance and manageability.

Row Format vs. Column Format

Oracle Database has traditionally stored data in a row format. In a row format database, each new transaction or record stored in the database is represented as a new row in a table. That row is made up of multiple columns, with each column representing a different attribute about that record. A row format is ideal for online transaction systems, as it allows quick access to all of the columns in a record since all of the data for a given record are kept together in-memory and on-storage.

A column format database stores each of the attributes about a transaction or record in a separate column structure. A column format is ideal for analytics, as it allows for faster data retrieval when only a few columns are selected but the query accesses a large portion of the data set.

But what happens when a DML operation (insert, update or delete) occurs on each format? A row format is incredibly efficient for processing DML as it manipulates an entire record in one operation i.e. insert a row, update a row or delete a row. A column format is not so efficient at processing row-wise DML: In order to insert or delete a single record in a column format all of the columnar structures in the table must be changed.

Up until now you have been forced to pick just one format and suffer the tradeoff of either sub-optimal OLTP or sub-optimal analytics performance.

Oracle Database In-Memory (Database In-Memory) provides the best of both worlds by allowing data to be simultaneously populated in both an in-memory row format (the buffer cache) and a new in-memory column format.

Oracle enlaza sus aplicaciones de inteligencia social a LinkedIn


CIO PERÚ



Oracle ha enlazado su suite de software SRM (social relationship management) a LinkedIn, una acción para proporcionar al personal de marketing y soporte al cliente una forma de alcanzar a los 300 millones de usuarios de la red social de negocios.

La integración con LinkedIn proporciona la capacidad de publicar páginas de LinkedIn Company y Showcase, las cuales pueden apuntar a un público seleccionado de acuerdo a factores como la localización geográfica, tamaño de compañía e industria, sostuvo Oracle en su anuncio.

También será posible interactuar con comentarios en estas páginas, señaló Oracle. También hay algo de analítica, como reportes sobre el número de comentarios que una publicación en particular ha generado, de acuerdo a Oracle.

Oracle SRM es solo un componente del grupo de herramientas de software que apuntan a alcanzar a los clientes y prospectos a través de múltiples canales, y que construyó a través de una serie de adquisiciones en los pasados dos años.

Para ese fin, también el miércoles, Oracle anunció una serie de mejoras a varios componentes en su familia de productos de nube para marketing.

Una de las actualizaciones importantes se centra en el llamado modelamiento “look alike (verse igual)”. Este tipo de modelamiento permite a los equipos de marketing que buscan nuevos prospectos hacer su trabajo mediante la construcción de modelos basados en clientes con atributos deseables.

Los marketeros pueden luego aplicar los modelos a la plataforma BlueKai de Oracle, la cual agregar información de perfiles de clientes de más de 200 proveedores de datos. Los marketeros pueden buscar en los cientos de millones de perfiles a los que da acceso BlueKai y encontrar las igualdades para sus modelos look alike.

Es posible generar modelos “muy ricos” con tan solo unos cuantos clics, sostuvo John Stetic, vicepresidente de productos de grupo de nube para marketing de Oracle.

Otra mejora anunciada apunta a enviar contenido de marketing a dispositivos móviles.

“Todos se dan cuenta que la movilidad está afectando las actividades de marketing”, afirmó Steve Krause, vicepresidente de gestión de productos de nube para marketing de Oracle. “Ves la necesidad de mejorar la movilidad en todos lados”.

Responsys, la herramienta de automatización de marketing de Oracle, puede ahora enviar notificaciones SMS a los clientes con dispositivos móviles, pero con un nivel de sofisticación mayor que simplemente un mensaje general a una gran lista de clientes.

Por ejemplo, los clientes pueden optar personalmente por recibir mensajes SMS de un sitio web que tiene ofertas que involucren cantidades limitadas de un producto; el SMS serviría para notificarles que se apuren si desean el producto.

“Estamos pasando de un modelo en donde todos reciben el mismo SMS a un modelo en donde es más personalizado”, indicó Krause. “Este es un gran cambio. Necesitamos dar a los marketeros la capacidad de enviar su mensaje a los clientes cuando y donde lo quieran”.

Oracle Database 12c Upgrade/Migration using Full Transportable Export/Import in MOS

Oracle Database 12c Upgrade/Migration using Full Transportable Export/Import 

This article describes how to perform a Database upgrade/migration to Oracle Database 12c with less downtime by using the new Oracle Database 12c feature Full Transportable Export/Import.

The traditional methods such as export/import, Datapump export/import and Transportable tablespaces, can still be used to upgrade/migrate a database to Oracle Database 12c. However, Oracle Database 12c now provides another method with the new feature called Full Transportable Export/Import making the migration/upgrade easier, faster and more efficient.


Let's look at a brief comparison of the various methods:

Upgrade using Database upgrade assistant (DBUA)
  • requires more downtime
  • migration across platform is not possible
Conventional export/import
  • relatively slow
  • not preferred method for large database size systems
  • reliable migration technique, but only recommended for Oracle 9i and earlier databases
Datapump export/import (introduced with Oracle Database 10g)
  • designed to handle large volume of data
  • replaces original export/import as the most common way to move data between Oracle databases
  • overtaken by Transportable tablespace method in terms of performance
Transportable tablespaces
  • achieves upgrade/migrate faster by copying database files to target system
  • requires additional steps to move user and system metadata to destination database
  • user objects associated with non user tablespaces (system and sysaux tablespaces) needs to be taken care manually
  • database file conversion will be required in case, source and target have different Endian format
Full Transportable Export/Import
  • uses both Transportable tablespaces mechanism and Datapump features
  • Transportable tablespace mechanism is used to move database files to target system resulting in faster migration even for large volume of data
  • Datapump is used to move metadata to target database
  • Complete migration with single import command
  • Capable of moving all required user data and metadata to migrate a database

Kai Yu, My Presentations at Oracle Openworld 2014

I will be presenting or co-presenting the two following sections at Oracle OpenWorld 2014. This marks my 9th consecutive Oracle Openworld conferences that I have presented. From 2006-2013, I have presented 22 technical sessions or panels at 8 Oracle OpenWorld conferences.

1. Session ID: UGF3431: Implement and Manage IaaS and a Self-Service Portal with Oracle Enterprise Manager 12c
(IOUG Sunday session)

Abstract: In Infrastructure as a Service (IaaS) cloud model, users can request the infrastructure for applications through the Self Service Portal. This session will focus on how to implement such a Iaas Self-Service with Oracle Enterprise Manager (EM) 12c and Oracle VM. This session will cover the IaaS cloud architecture; creation of VM templates/ assemblies using Virtual Assemble Builder (OVAB), and how to setup the Self-Service deployment mode with Oracle VM templates and virtual assemblies. You will learn the configuration of the entire stack of this infrastructure cloud built on Dell platform and how to use EM12c to manage the entire stack of the cloud architecture including hardware through Oracle EM12c’s Dell Dell OpenManage plug-in.
Speaker: Kai Yu

2. Session ID: CON5433: Leveraging New Oracle Database 12c Features to Reduce Storage Costs
OOW weekday section
Abstract
Advances in flash storage are driving ever-increasing performance. And while the price per GB continues to decrease, the absolute cost of top-tier storage offerings is on the rise. One way to combat the high cost of flash storage is to tier data across multiple types of disks to leverage the cost and capacity of conventional spinning disks. This session shows you how to reduce your storage costs without compromising performance, through automatic tiering of your data with two new Oracle Database 12c features: Heat Map and Automatic Data Optimization
Speakers: Wes Vaske, Kai Yu
