Last year, Oracle acquired BEA Systems, the hottest company in enterprise Java…until around 2001. Today, they announced the acquisition of Sun Microsystems, the architects of the infrastructure of the dot com era. Remember the “dot in dot com”?
Both companies represent the history of enterprise Java, and are far less important to the future. Continue reading it here.

Larry Ellison has always wanted to be the Steve Jobs of the enterprise. With this morning’s announcement that Oracle will buy Sun Microsystems for $7.4 billion, he took a big step towards making Oracle more of a soup-to-nuts provider of enterprise technology. With Sun, he will now be able to build and package together everything from chips and servers to operating systems, Java middleware, databases, and enterprise applications. Continue reading it here.

Boy, it sure was polite of Sun and Oracle to wait until the day I got back from my vacation to announce their merger, wasn’t it? I fulminated gloomily about this possibility before I left, but now that I’ve spent a day absorbing the news, I’m … slightly less gloomy. Continue reading it here.

A community weighs the pros and cons of Oracle’s new claim on Java.
While Oracle and Sun Microsystems are hailing Oracle’s purchase of Sun as a big boost for Java, others are not so sure. Some with stake in the Java ecosystem are questioning what kind of control Oracle might try to exercise over the popular software development platform, which has driven enterprise applications since its debut in 1995. Observers also expect Oracle to make a go of trying to make more money off of Java than Sun ever could. Continue reading it here.

Oracle CEO cites Java, Solaris as key components of acquisition.
Oracle may have decided to buy Sun Microsystems because it was worth far more to the database market leader than it was to IBM. It’s not a question of the price — at $7.4 billion, Oracle didn’t agree to pay much more than what IBM reportedly was considering. But Oracle may have more use for Sun’s technology than IBM ever did.

Redbook – z/VM and Linux Operations for z/OS System Programmers – 2008
This IBM Redbooks publication discusses z/VM and Linux operations from the perspective of the z/OS programmer or system programmer. Although other books have been written about many of these topics, this book gives enough information about each topic to describe z/VM and Linux on IBM System z operations to somebody who is new to both environments. This book is intended for z/OS programmers and system programmers who are transitioning to the z/VM and Linux on System z environments and who want a translation guide for assistance. We base this book on our experiences using System z10 Enterprise Edition, z/VM version 5.3 RSU 0701, and Novell SUSE Linux Enterprise Server (SLES) 10 on System z.
Redpaper – Sharing and maintaining Linux under z/VM – 2008
Large operating systems, such as z/OS , have, for several decades, taken advantage of shared file structures. The benefits of a shared file structure are reduced disk space, simplified maintenance, and simplified systems management. This IBM Redpaper describes how to create a Linux solution with shared file systems on IBM System z hardware (the mainframe) running under z/VM. It also describes a
maintenance system where the same Linux image exists on a test, maintenance and gold virtual servers.
Redpaper – A Shared WebSphere Application Server Installation for Linux on zSeries – 2005
This IBM Redpaper describes a process to enable sharing one WebSphere Application Server installation among many Linux guests running under z/VM.
Redbook – Linux on IBM eServer zSeries and S/390: Best Security Practices – 2004
This IBM Redbook discusses best security practices for running Linux as a z/VM guest on IBM eServer zSeries and S/390 machines. This publication is intended for system administrators and IT architects responsible for deploying secure Linux servers running under z/VM. We consider both z/VM and Linux security topics.

Redpapaper – Linux on IBM eServer zSeries and S/390: z/VM Configuration for WebSphere Deployments – 2003
In this Redpaper, we introduce a method to determine an efficient infrastructure for WebSphere deployment on Linux for zSeries. The infrastructure consists of LPARs running multiple Linux guests under VM. Each Linux guest runs WebSphere, which in turn runs Web applications. In this paper, we describe steps to configure z/VM Linux guests intended to run WebSphere applications. Specifically, we outline a method to calculate the memory required to deploy WebSphere applications, and describe how that memory should be allocated to the LPAR, z/VM, and Linux guests.

Estou fazendo MBA em Sistemas Corporativos de Alto Desempenho na FIAP. O objetivo do cursos e estudar arquitetura do servidores que possuem alta disponibilidade no mercado. Basicamente vamos estudar arquitetura CISC (mainframe) e seus principais sistemas Operacionais tal como Z/OS e Z/VM.
Na arquitetura RISC, estamos estudando os UNIX da IBM (AIX) da HP (HP-UX), SUN (Solaris) e o Linux.
Quando se fala em Linux no server side duas distribuições linux dominam o mercado, sendo a Red Hat e o Open SUSE da Novell.
Mas que tipo de Hardware em se tratando do server side hoje rodam linux. Foi dai que encontrei um pesquisa feita por clientes do Canonical que é a empresa por trás do Ubuntu Linux. Ubuntu Linux é uma distribuição lider para desktop linux, e também existe a distribuição Ubuntu Server, que ainda está conquistando mercado.
O gráfico acima é baseado em uma pesquisa feita pela Canonical chamada popularity of the Ubuntu server system. Embora o estudo tenha sido feito como base os clientes da Canonical, podemos ver quais tipos de hardware e vendors que hoje usam o Linux.
Realmente recomendo fazer o download da pesquisa feita pela Canonical, onde além dessa informações contém outras informações interessantes sobre o uso do Linux.

O renomeado jornal Wall Street Journal publicou uma reportagem sobre o Ronaldo como o título Espere, é aquele Ronaldo ?
Bom, para quem é brasileiro e acompanha os noticiários de esporte, não tem nada de novidade, mas para para o resto do mundo ele resume a trajetória do Ronaldo depois de vencer a copa do mundo de 2002.
O jornal menciona que Ronaldo ainda está acima do peso, mas continua motivado como sempre, sendo que em 7 jogos ele fez 5 gols. É que a vida do “country’s most famous player after Pelé” jogador mais famoso depois de Pelé (acho que o Romario não gostou disso) está longe de ser o glamur dos tempos de Europa. “Nowadays he splits $89-a-night rooms with teammates in remote Brazilian burgs with names like President Prudent” Hoje em dia Ronaldo devide o quarto de 89 dolares a noite com seus companheiros de time em remotas cidades do interior como Presidente Prudente. Mas como fontes afirmam, Ronaldo está feliz “It’s been two years since he’s had the kind of attention he has now,” says Jose Ferreira Neto, a former Corinthians star and TV sports commentator. “I’ve never seen him so happy.” Fazem 2 anos que Ronaldo não recebe esse tipo de atenção, como ele está recebendo agora, e ele está mais feliz do que nunca, afirma o comentáista do Sport TV Jose Ferreira Neto e ex jogador do Corinthians.
Sobre o Corinthians o artigo declara: “It’s also a comeback for the Corinthians, a team famed for its rabid cadre of 25 million fans, dubbed “the Faithful.” In 2007, the club had been demoted to a second-tier league, and prosecutors accused its top management of laundering money and having links to Russian mobsters.”
Ronaldo voltou para um time como o Corinthians um time famoso por sua torcida de 25 milhões de torcedores, conhecida como “Fiel”. Em 2007 foi rebaixado para a segunda devisão e foi acusado que seus que seus diretores estariam fazendo lavagem de dinheiro e tinham conexão com os gângster Russos.
O artigo finaliza que “For the new management trying to rebuild the Corinthians franchise, Ronaldo’s story was a perfect fit. “I’ve been trying to explore the Rocky in ourselves all year long,” says Luis Paulo Rosenberg, Corinthians director of marketing. “Our focus is on self-esteem, to make [fans] forget the humiliation.”” os diretores do Corinthians estão tentando construir um Corinthians como uma marca, é a historia de Ronaldo se encaixa no Corinthians, quando o diretor de Marketing do Corinthians Luiz Paulo Rosenberg afima que durante o ano, Corinthians e Ronaldo estarão na midia para ajudar na auto estima dos dois, do Ronaldo voltando a ser o que ele já foi, e para p Corinthinas esquecer a humilhação da segunda divisão.
