DevLoop has just published a free paper (US mirror) benchmarking some popular database systems such as MySQL, PostgreSQL, Firebird, DB2, Informix, Sybase SQL Anywhere, on Linux using JDBC. The focus here is on non-real setups where we can analyze the individual aspects that might affect system performance. The code is available (GPL) so that anyone can reproduce the results.
"At the time, most of us thought Oracle undercutting Red Hat's Linux business with its Unbreakable Linux was a big deal. Would customers flock to Oracle's cut-rate version of RHEL? Would Red Hat be pounded by Larry Ellison's minions? After a few months, the answers appear to be: No, it wasn't a big deal; and no; and no."
Oracle on Tuesday released fixes for 51 vulnerabilities that affect its software products. The update is part of the company's quarterly patch cycle. Oracle preannounced its patch release Thursday, when, for the first time, it published an advance notification so customers could plan ahead to apply the fixes.
Open-source database company MySQL has decided to stick to the current General Public License rather than move to an upcoming revision, pending broader industry acceptance. MySQL, one of the most successful commercial ventures to use the GPL, has modified its license terms from 'version 2 or later' to 'version 2' only, according to Kaj Arno, the company's vice president of community.
MySQL quietly deprecated support for most Linux distributions on October 16, when its 'MySQL Network' support plan was replaced by 'MySQL Enterprise.' MySQL now supports only two Linux distributions - Red Hat Enterprise Linux and SUSE Linux Enterprise Server. We learned of this when MySQL declined to sell us support for some new Debian-based servers. Our sales rep 'found out from engineering that the current Enterprise offering is no longer supported on Debian OS.' We were told that 'Generic Linux' in MySQL's list of supported platforms means 'generic versions of the implementations listed above'; not support for Linux in general.
Microsoft is beating Oracle hands down with the security of its database, according to a new report. David Litchfield, a security researcher with NGS Software, published a whitepaper entitled Which database is more secure? Oracle vs. Microsoft on 21 November comparing the number of software vulnerabilities patched by both vendors in their respective products in the past six years.
"I had a few minutes to burn today, so I did what I'm sure you were doing: I read the Oracle Enterprise Linux Services Agreement. It's funny what you find when you start digging around in the legalese that governs the Big Announcement that Oracle made. It makes 'Unbreakable Linux' look a little flimsy."
After 2 years in development, the Firebird Project today officially releases the much-anticipated version 2.0 of its open source Firebird relational database software during the opening session of the fourth international Firebird Conference in Prague, Czech Republic.
Red Hat has officially responded to Oracle's 'Unbreakable Linux' move. "The opportunity for Linux just got bigger. Oracle's support for Linux reaffirms Red Hat's technical industry leadership and the end of proprietary Unix. It's no accident that Red Hat was chosen #1 in value two years running. Want to know what else we think? Read on." This article has more reactions.
"Yesterday Oracle announced the release of their own version of Red Hat Enterprise Linux, simply called Enterprise Linux or 'Unbreakable Linux'. In a remarkably similar move to such projects as CentOS, Oracle have decided to remove all Red Hat specific trademarks and brand it as their own (all quite legit, of course). They will be supplying bugfixes for this new version, and will also be synchronising it with future releases of Red Hat Enterprise Linux. We decided to take a peek at what Oracle had come up with. Read on for a first-look, and the Linux Format team's opinions." In the meantime, Mark Shuttleworth said a partnership with Oracle is no longer a matter of if, but when.
"No one saw this coming. People talked about Oracle making its own Linux, or buying a Linux company (Ubuntu?). But, the news that Oracle is erasing Red Hat's trademarks from Unbreakable Linux and supporting it for less than Red Hat is a bolt from the blue. Or, perhaps, I should say that Oracle is firing a shot at the heart of Red Hat, and commercial Linux? This really, really ticks me off." Apparently, Oracle announced that they will provide full enterprise support for Linux and so it competes with RH.
The popular MySQL database is slated for a future split between what MySQL AB calls the Community and the Enterprise versions. Read the official announcement and further opinions and explanations from Kaj Arno (MySQL VP of Community Relations) and Stephen O'Grady (software industry analist). In Arno's own words: "We recognise that the needs of the MySQL Community are different from the needs of commercial enterprise customers. After 11 years of producing our software, we can no longer hope that a single offering is the best solution for both Community and Enterprise users. Consequently, we are introducing two different offerings for each distinct target group."
"This tutorial describes how to set up MySQL master-master replication. We need to replicate MySQL servers to achieve high-availability. In my case I need two masters that are synchronized with each other so that if one of them drops down, other could take over and no data is lost. Similarly when the first one goes up again, it will still be used as slave for the live one. Here is a basic step by step tutorial, that will cover the mysql master and slave replication and also will describe the mysql master and master replication."
The new version of Berkeley DB, the OSS embeddable database Oracle acquired along with Sleepycat, promises better performance and the ability to do upgrades on the fly. But does Oracle really have open source street credibility? One expert says not really. On other DB news, check this audiocast on PostgreSQL while Zmanda launched the first comprehensive backup solution for MySQL.
In this tutorial, you'll learn to set up a DB2 9 database and WebSphere Application Server Community Edition on a Windows or Linux environment, then write and deploy a Java application that takes advantage of the pureXML capabilities in DB2 9.
Attendees of the recent New England Oracle Applications User Group conference got a refresher course on some of the key tools that Oracle developers use to customize E-Business Suite applications. Sridhar Bogelli, the leader of the session and founder and chief executive officer of Apps Associates, an application development consultancy, told attendees that properly using the tools provided by Oracle and third-party vendors can help developers and their companies avoid embarrassing, production-related problems.
Many open source software users, consultants and other IT pros believe that Oracle's recent moves in the OSS market - including its purchases of open source stalwarts Sleepycat Software and Innobase - were undertaken as part of an effort to destabilize Microsoft.
"You might be surprised to know that you can connect Excel to a database, and this isn't limited to databases running Microsoft's SQL. Excel can connect to practically any mainstream database (MySQL, PostgreSQL, Oracle and others), provided that the database offers an ODBC (Open DataBase Connectivity) driver. In this article, you'll learn how to connect MySQL to Excel."
Open source is hot these days, and Oracle knows it. The company is facing challenges from open source competitors by embracing open source technology in its own right - acquiring and developing key companies and products in this area - as well as fighting to show its merits over other open source choices. How does Oracle stack up against PostgreSQL? How do Oracle and Linux work together? What's next for Oracle on the open source front?
