My Experience Using Oracle SQL Plan Baselines 11g/12cNelson Calero
This presentation shows how to use the Oracle database functionality SQL Plan Baselines, with examples from real life usage on production (mostly 11gR2) and how to troubleshoot it.
SQL Plan Baselines is a feature introduced on 11g to manage SQL execution plans to prevent performance regressions. The concepts will be presented, along with examples, and some edge cases.
Any DBA from beginner to advanced level, who wants to fill in some gaps in his/her knowledge about Performance Tuning on an Oracle Database, will benefit from this workshop.
This is a recording of my Advanced Oracle Troubleshooting seminar preparation session - where I showed how I set up my command line environment and some of the main performance scripts I use!
Using Kubernetes to deliver a “serverless” serviceDoKC
Serverless promises to change the way we consume software. It allows us to potentially pay for only that which we use and can help drive down operational costs to the minimal amount of resources necessary.
Architecting for serverless requires a unique look at app logic and the way it is deployed. It takes a combination of the logical and physical worlds. An architectural pattern has emerged where we can scale ephemeral compute separate from services that need to persist.
We use Kubernetes to deliver exactly this. A “serverless” experience that is driven and enabled by compute pods and storage pods. We also have used our experience running thousands of database clusters on Kubernetes to automate the operational expertise of managing a distributed database.
In this talk, we will take a dive deep into the architecture of our application and share:
* A definition and outline of the challenges of serverless
* How we reworked our logic for a serverless approach
* How we use Kubernetes to gain serverless autoscaling

Schizophrenic High Availability with SQL and Windows 2016Mark Broadbent
As SQL Server and Windows availability solutions have reached maturity, their capabilities and interoperability has grown to such an extent that it is no longer clear what technologies to use, when to use them, what they deliver and when things can go wrong.
In this session we will take a look at some of the new features provided by SQL Server and Windows 2016, how existing high availability solutions can benefit from their adoption and when schizophrenic HADR can be bad idea!

Mastering Chaos - A Netflix Guide to MicroservicesJosh Evans
QConSF 2016 Abstract:
By embracing the tension between order and chaos and applying a healthy mix of discipline and surrender Netflix reliably operates microservices in the cloud at scale. But every lesson learned and solution developed over the last seven years was born out of pain for us and our customers. Even today we remain vigilant as we evolve our service architecture. For those just starting the microservices journey these lessons and solutions provide a blueprint for success.
In this talk we’ll explore the chaotic and vibrant world of microservices at Netflix. We’ll start with the basics - the anatomy of a microservice, the challenges around distributed systems, and the benefits realized when integrated operational practices and technical solutions are properly leveraged. Then we’ll build on that foundation exploring the cultural, architectural, and operational methods that lead to microservice mastery.
Persistence Is Futile - Implementing Delayed DurabilityMark Broadbent
The concurrency model of most Relational Database Systems are defined by the ACID properties but as they aim for ever increasing transactional throughput, those rules are bent, ignored, or even broken.
In this session, we will investigate how SQL Server implements transactional durability in order to understand how Delayed Durability bends the rules to remove transactional bottlenecks and achieve improved throughput. We will take a look at how this can be used to compliment In-Memory OLTP performance, and how it might impact or compromise other things.
See this session and you will be assimilated!
Lockless in Seattle - Using In-Memory OLTP for Transaction ProcessingMark Broadbent
Locks and latches have long been the mechanism used to implement SQL Server concurrency control, but with the introduction of In-Memory OLTP the paradigm has shifted. Are we really looking at the Brave New World of Transaction Processing or a dystopian nightmare?
In this session, we will understand how In-Memory OLTP architecture is implemented and how its mechanics function. We will learn what transactional bad dependencies and other considerations are introduced by its use and what capabilities are provided by SQL Server 2016.
SharePoint is from Mars, SQL Server is from Venus (SQL Server for SharePoint ...Mark Broadbent
The SQL Server Database Engine is a prerequisite and fundamental part of any SharePoint deployment but the downside to all of this is the Database Server usually brings a Database Administrator with it. In this session we will explain how to configure SQL Server correctly with SharePoint deployments in mind, how the underlying architecture and mechanisms of SQL Server work and why you need to do all this! By the end of this session you will have learnt how to talk to your DBA to explain that they are doing it wrong!
SQL Server is a high performance relational engine and provides a highly scalable database platform but due to its complexity, bad programming practices, poor indexing and configuration can be prone to serious concurrency problems, unexpected behaviors, lost updates and much more! In SQL Server 2005, two optimistic concurrency mechanisms were introduced and touted as the solution to all our problems. Now in SQL Server 2012 and SQL 2014 even more have followed including latch free data-structures, but many challenges and problems still remain. Let’s take a long look into the world of SQL Server concurrency and investigate Pessimistic and Optimistic isolation understanding how they work, when you should use them, and more importantly when they can go very wrong. Don't be staring down the wrong end of SQL Server's two Smoking Barrels and join me for this revealing and thought provoking presentation.

Enter The Dragon - SQL 2014 on Server Core - SQLSaturday #341 Porto EditionMark Broadbent
In 1982 the Dragon32 entered the home computer market but unfortunately there was one small problem ...lower-case letters were almost impossible to access. Two years later Dragon was no more. In 2008 Microsoft released ServerCore providing a fast and streamlined (but reduced functionality) edition of Windows with minimal GUI support and with Windows 2012/R2 Server Core is "by default". Ever since SQL 2012, installation onto Server Core became a "supported" option and meant the single biggest administrative shift for a DBA since the release of SQL 2005 ...or did it? In this exciting session we will discuss administration, configuration and installation of both SQL 2014 and ServerCore in both standalone and advanced AlwaysOn configurations but will the lack of GUI support send Server Core in the same direction as the Dragon32 or spell a bright new beginning for Server based computing and SQL Server?
Welcome to the strange and mysterious world of SQL Failover Clustering and enter Ye Olde Cluster Curiosity Shoppe where we will reveal a miscellany of top tips, tricks and advice gained from nearly two decades of installing and troubleshooting SQL Clusters.
Roll-up roll-up! Come and see :-
The "multi-headed" cluster.
The installation of Death.
The Zombie.
The Marie Celeste.
The indestructible network name.
And many more weird and wonderful exhibits.
Concurrency is probably one of the most important subjects in SQL Server, but one of the least talked about -and one of the most misunderstood. We will attempt to delve into the world of Transactions, Locking and Isolation and reveal some of SQL's dirty little secrets.
PASS 2012 "Moves Like Jagger" - Upgrading to SQL Server 2012Mark Broadbent
Upgrading SQL Server is one of the most challenging and risky operations that you will perform as a DBA. Make the wrong move and you could be heading for the exit. Upgrade does not end when you think so you should prepare for the worst and aim for success.
Thinking outside the box, learning a little about a lotMark Broadbent
Being a SQL specialist is not enough. Windows and the interfaces SQL consumes are becoming ever more complex. Being aware of these technologies and beyond can make you a better DBA. You will learn how to become a DBA 2.5, SQL Enterprise name resolution strategies, create your own private VSAN & VCluster, fail instances BETWEEN separate clusters and use the CLR to manage the OS from SQL.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

• Set connection string property

32. In Summary…
• It is not all Butterflys and Unicorns so choose the
HA solution appropriate to your requirements.
• Failover Clustering is a very mature technology
but requires specialist skill and understanding. It
does not provide scalability.
• Availability Groups partially rely on Windows
Clustering but are slightly easier to setup and
manage. They also provide reporting query
scalability.
