The end is nigh for Adobe Flash at My Oracle Support. The first step will happen during this weekend’s planned maintenance of My Oracle support, when all of MOS will be down for 5 hours starting at midnight eastern, Saturday January 28. Once it comes back up, the unadvertised non-Flash supporthtml.oracle.com will come up as a quasi-user acceptance test of the new application, while the flash-based support.oracle.com stays as-is.
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
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.
Hot on the heels of 188.8.131.52 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.
DuckFeet’s guts are SQLicious, and built as DBIx::Class classes, sprinkled with wonderfully tooth-decaying DBIx::Class::Candy on top. In the repo, it’s all under the DuckFeet::Schema namespace. For the time being, there is only a handful of tables (hits, uris, referers, agents and hosts), but it should be easily extendable to add any type of information we might desire to throw in, but it should be easily extendable to add any type of information we might desire to throw in.
Since Oracle 184.108.40.206 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.
In this post I quickly cover the new features in SQL Server RC0 setup.
How much memory does my Oracle instance use? How much memory do my database connections use? These are questions that can help with capacity planning of your server’s Physical and Virtual memory. There are several write ups out there on the web that attempt to address these questions. From what I could gather from them, there is only one truly good way to tell exactly how much memory is currently in use by an oracle instance, as well as the average memory usage for oracle dedicated connection processes. I explain it here.
In this post I’ll Briefly cover the changes to SQL Server licencing which happened in two areas, edition changes and licensing changes. Lets get started.
I had to refresh my knowledge on how InnoDB threads queue works the other day when debugging activity spikes on one of the customer’s production system and while I had general idea about InnoDB kernel and queue, thread concurrency and queue join delays I didn’t have a complete model of how InnoDB concurrency control works. So I started from manual…
