Over the last couple of months, the wonderful folks from Oracle Australia have been running a FREE virtual training event on what to expect from Oracle Database 19c and how to prepare to upgrade to the latest long-term support release of the Oracle Database.
The first 5 sessions covered everything you would want to know about how to upgrade and what you can expect from Oracle Database 19c including an in-depth look at the new Multitenant architecture. The sessions so far have been presented by some of the best Oracle speakers around including Mike Dietrich, Julian Dontcheff, Martin Bach, Richard Agnew, and Alex Blyth. All of the sessions so far have been recorded and are available for replay.
Under the Hood of an Autonomous Database
The final session in series is scheduled for August 11th at 10am AEST ( August 10th at 5 pm PST) and will be presented by Alex Blyth and myself. In our session, we plan to give you a peek under the hood of the Oracle Autonomous Database and provide you with a clear understanding of how this unique autonomous database works. We’ll share details on the exclusive combination of Oracle Database 19c features, best practices, and machine-learning algorithms used to deliver this family of cloud services. We’ll use live demos to show you how it can simplify your approach to data management with Oracle Database 19c and accelerate your transition to the cloud.
You can registers for this session here. Hope you can join us!
Last week I had the pleasure of delivering a five-part SQL Tuning Workshop for my local Oracle User Group – Northern California Oracle User Group. The workshop explains the fundamentals of the cost-based optimizer, the statistics that feed it, the hints that influence it and key tools you need to exam executions plans.
The workshop also provides a methodology for diagnosing and resolving the most common SQL execution performance problems. Given the volume of interest in this content, I want to share all of the material from the workshop here and give you links to additional material on each of the 5 topics.
Part 1 Understanding the Oracle Optimizer
The first part of the workshop covers the history of the Oracle Optimizer and explains the first thing the Optimizer does when it begins to optimize a query – query transformation.
Query transformations or the rewriting of the SQL statement into a semantically equivalent statement allows the Optimizer to consider alternative methods of processing or executing that query, which are often more efficient than the original SQL statement would allow. the majority of Oracle’s query transactions are now cost-based, which means the Optimizer will cost the plan with and with the query transformation and pick the plan with the lowest cost. With the help of the Optimizer development team, I’ve already blogged about a number of these transformations including:
You can also download the slides here.
Part 2 Best Practices for Managing Optimizer Statistics
Part 2 of the workshop focuses on Optimizer Statistics and the best practices for managing them, including when and how to gather statistics, including fixed object statistics.

I can’t believe Oracle Open World is done for another year.
But what a great conference it was for those interested in the Oracle Database. We saw the introduction of Oracle Database 20c and of course the continuing evolution of the Oracle Autonomous Database with details on new deployment option (Dedicated) and new flavors (Document Store).
If you weren’t able to make it to OOW in person, don’t panic as a lot of the session presentations are now available for download in the OOW session catalog. You can download the slides by clicking the down arrow on the right-hand side of each session title as shown below.

With less than a week to go until Oracle Open World kicks off, I thought I would share with you what you can expect.
Of course the whole Database team will be there and you will have multiple opportunities to meet up with us, in one of our technical sessions, our hands-on-labs or at the Oracle demogrounds.
Below are just some of the session I thought might be interesting to help get you started:

The first day of the ODTUG Kscope conference is always symposium Sunday. This year’s Database symposium, organized by @ThatJeffSmith, consisted of multiple, short, rapid sessions, covering a wide variety of database and database tool topics, similar to Ted Talks but we called then JEFF Talks!
I was lucky enough to present 3 of this year’s JEFF Talks that I thought I would share on my blog since there wasn’t a way to uploaded to the conference site.
In the first session I covered 5 useful tips for getting the most out of your Indexes, including topics like reverse key indexes, partial indexes, and invisible indexes.
Next up was my session on JSON and the Oracle Database. In this session, I covered topics like what data type you should use to store JSON documents (varchar2, clob or blob) the pros and cons of using an IS JSON check constraint, and how to load, index, and query JSON documents.
In my finally JEFF talk I covered some of the useful PL/SQL packages that are automatically supplied with the Oracle Database. Since the talk was only 15 minutes I only touched on 4 of the 300 supplied packages you get with Oracle Database 18c but hopefully it will give you enough of a taste to get you interested in investigating some of the others!
Believe it or not, it’s time to start thinking about Oracle OpenWorld 2018!
The Oracle OpenWorld 2018 call for papers is now opens! Oracle customers and partners are encouraged to submit proposals to present at this year’s Oracle OpenWorld conference, which will be held October 22-25, 2018 at the Moscone Center in San Francisco.
Details and submission guidelines are available on the Oracle OpenWorld Call for Papers web site. The deadline for submissions is Thursday, March 22, 11:59 p.m. PDT.
We look forward to checking out your sessions on the Oracle Database and how it has changed the way you do business!
It’s the last day of Oracle OpenWorld and we have saved the very best for last. So hopefully you are still awake and functioning at this stage!
You can start the day off at 12 noon in Moscone West, room 3020 with the Maria & Gerald Venzl show! In this session we will share the Oracle Database Features Every Developer Should Know About. Using clear, easy to follow examples we will explain how you can put these features to work in whatever project you are doing.

Hopefully you enjoyed yesterday, the second full day of technical sessions at Oracle OpenWorld and are ready for more today!
At 11:30 am today I give my first technical session, with the wonder Dominic Giles of Swingbench fame!
Dom and I will be talking about the Oracle Database & the Internet of Things in Moscone West, room 3011. In this session we will provide step-by-step instructions for deploying a high-ingest, mission critical IoT workload on Oracle D atabase. There will be even some demos to proving the impact of each recommendations. So don’t missing it!
You can also get a SQLMaria laptop sticker at the session!

Oracle OpenWorld started yesterday and San Francisco is just buzzing with Oracle folks and the excitement generated by the new Oracle Autonomous Database announcements made by Larry Ellison during last night’s keynote!
If you are interested in more information on the Autonomous Database and how it’s changing the roll of the DBA, be sure to check out the “Preview of Oracle Autonomous Database” that Juan Loaiza‘s and I will present on Wednesday at 3:30pm in Moscone West, room 3014.
But what about session picks for today?
