With winter and its cold weather starting to set in across most of the world, now is the time when travelers start to think about warming things up. For most, that means flying to hot and sunny destinations. Another way of looking at it, however, is to head out for a different kind of sizzle. There’s perhaps no better way to heat up the chilling months with blogging. Let’s snuggle up in this Log Buffer Edition with hot blog posts in Log Buffer #255.
Whenever I tell an experienced Oracle DBA about Hadoop and what companies are doing with it, the immediate response is “But I can do this in Oracle”. Let’s compare.
The 2012 edition of RMOUG Training Days in Denver less than a month away, running February 15 and 16 at the Colorado Convention Center in Denver. . It’s not too late to register, and it’s a pretty nice excuse to get to the Rockies in ski season. I’ll be doing two presentations, and am polishing up whitepapers and presentations for the submission deadline tomorrow
After having party and festive time during holidays, bloggers are returning with reinvigorated zest and with uplifted zeal and the blogs are sprouting energy and promise. The new year is already here and the blogs across the database rainbow are oozing colors of all kinds. This Log Buffer Edition depicts some of them in Log Buffer #254.
With the announcement of the Oracle Big Data Appliance, Oracle also comes up with some really cool technology stack which is being termed as Oracle Big Data Connectors (OBDC). This piece of software can be used with both Oracle Big Data Appliance and other Apache Hadoop-based systems.
At this time there are three Hadoop appliances in the market:Oracle’s Big Data appliance, Netapp’s Hadooplers and EMC’s Greenplum DCA. It looks like a lot of companies that did not already adopt Hadoop in 2011, are looking to do so in 2012, and some of them may be considering going with an appliance. I want to take a look at some of the reasons a company will be interested in a Hadoop appliance, and what are the differences between the different appliances.
I attended a great presentation at UKOUG 2011, “Oracle E-business Suite’s use of edition-based redefinition for online patching,” delivered by Bryn Llewellyn from Oracle. The presentation provided thorough insight on how EBR works and how E-Business Suite will be able to use it for online patching. It answered many questions, but raised a few more questions and concerns. I’ll try to summarize in this post the main concerns I’ve been thinking about after attending this presentation.
A very very Happy New Year 2012 to all of you. These are the festive and jubilant times when people look back on previous years and make plans for their new year and beyond. Well, this Log Buffer Edition is no different. This week covers the new year posts of the bloggers across the database arena in Log Buffer #253.
Hot on the heels of 220.127.116.11 coming out for Exadata, there’s yet another Exadata patch schedule out: the Quarterly Database Patch for Exadata (QDPE). They’re designed to being some of the predictability of Oracle’s quarterly critical patch updates (CPU) to the Exadata world.
Since Oracle 18.104.22.168 came out last September, there have been questions about Exadata availability. As of today, the patchset is now available.
Reviewing the upgrade document (MOS note 1373255.1) a few things that jumped out at me, here they are.
