I describe AlwaysOn Availability Groups as a “database mirroring configuration sitting on top of a Windows Failover Cluster infrastructure.” Why do I say this? It’s because I want SQL Server DBAs to leverage what they already know on features like database mirroring and failover clustering and apply them when dealing with AlwaysOn Availability Groups.
Following my “Building Integrated DWH with Oracle and Hadoop” webinar for IOUG Big Data SIG, I got a bunch of excellent follow up questions. The most frequently asked questions are: What is the minimum I need to do to get started with Hadoop? and How do I load data into Hadoop? Since so many people are interested in the same question, it makes more sense to answer on the blog.
Sky’s the limit for the database bloggers. They are producing awesome rants in Oracle, fabulous ramblings in MySQL, and fantastic views in SQL Server, and this Log Buffer Edition, very proudly covers all that in Log Buffer #303. Enjoy.
I recently helped setup an Exadata X2-8 Database Machine with the latest version of OEM Cloud Countrol (22.214.171.124). A few documents do exist for this process. However I found a few inconsistencies and problems; I think the existing documents I found were written on older versions of OEM and older versions of the tools. I’m publishing my final procedure here with hopes that it helps you, but as always please cross-reference this with the appropriate documentation before doing anything in your own environment.
No its not cloud or engineered system or JBOD, if you are wondering. Surely, it can be any of those thing, and anything else. It really doesn’t matter if your data resides in good, reliable, always-there hands. So what’s the destination of choice in this brand new year? Keep reading to find out.
This one was going to be a cry for help and a request to confirm that I’m not going cuckoo, but I think I figured it out. Still, for giggles, hear this:
There is no great joys for the bloggers to mark the holiday season with some blistering and lightweight blog posts. This Log Buffer Edition in Log Buffer #302 shares that mirth and presents you with another medley of blogs.
DBD::Oracle v1.54 is on its way to CPAN. In this iteration, no new feature, but a large amount of bug fixes.
It has come again. This magic time of the year when, in-between the hangovers of Christmas and the hangovers of the New Year bashes, one takes a longing look back at the ending year, and make mad plans, wistful wishes and grandiose resolutions for the new one. So, for a moment, let me indulge in this tradition and let my gaze wander at the distances that stretch forward and behind, while my mind drift back and forth betwixt what has been and what shall be. But gently. ‘Cause lemme tell you, that was damn good eggnog (so please be kind and don’t click so hard with the mouse, will you?).
What better way to start the year than to bring a fresh new breath to an old favorite? And thus, as you read this a new version of Git::CPAN::Patch should be making its way to CPAN. This new version is a massive refactoring of the module’s guts, which will affect both end-users and developers. For the best. Mostly. Or so I hope.
