Oracle Big Data Spatial and Graph enables the analysis of data sets beyond that of standard relational analytics commonly used. Through graph technology relationships can be identified that may not otherwise have been. This has practical uses including in product recommendations, social network analysis, and fraud detection.

In this presentation we will see a practical demonstration of Oracle Big Data Spatial and Graph to load and analyze the "Panama Papers" data set. Graph algorithms will be utilized to identify key actors and organizations within the data, and patterns of relationships shown. This practical example of using the tool will give attendees a clear idea of the functionality of the tool and how it could be used within their own organization.

When: Jun 27, 2017, Tuesday Session 7 , 11:15 am - 12:15 pm

OBIEE 12c is the latest generation of Oracle's Enterprise analytics and reporting tool, bringing with it many powerful new features. Many users are still on earlier releases of OBIEE 11g or even 10g, and are looking to understand how they can move to OBIEE 12c to benefit from its new capabilities.

Liberty Global is a global telecommunications company, with a long history with OBIEE going back to 10g. They wanted to move to OBIEE 12c in order to use the new Advanced Analytics options, and used Rittman Mead to support them with the full scope of the upgrade.

In this presentation, we will see what a highly successful OBIEE 12c migration looks like. We will cover clear details of all the steps required, and discuss some of the problems encountered. Regression testing is a crucial step in any upgrade and we will show how we did this efficiently and accurately with the provided Baseline Validation Tool. This presentation will assist all attendees who are considering, or in the process of, an OBIEE 12c upgrade.

When: Jun 26, 2017, Monday Session 5 , 4:45 pm - 5:45 pm
Room: Wisteria/Sunflower

And

As a DBA or sysadmin responsible for OBIEE how do you really dig into the guts of OBIEE, look at intra-component communication between the system components and examine the apparently un-examinable? What do you do when you need to trace activity beyond what is in the log files? How do you work with log files in order to give precise but low-level information? What information can be gleaned, by hook or by crook, from OBIEE?

OBIEE provides a set of systems management and diagnostic tools, but these only take you so far. Join me in this presentation to dive deeper with OBIEE. We will take a look at a bag of tricks including undocumented configuration options, flame graphs, system call tracing, discovering undocumented REST APIs, and more! This is not just a geek-out - this is real-life examples of where client OBIEE projects have required that next level of diagnostic techniques and tools. Don your beanie hat and beard as we go deep!

A focus on Higher Education, HEDW 2017

First, before I get into a great week of Higher Education Data Warehousing and analytics discussions, I want to thank the HEDW board and their membership. They embraced us with open arms in our first year of conference sponsorship. Our longtime friend and HEDW board member, Phyllis Wykoff, from Miami University of Ohio even spent some time with us behind the booth!

HEDW was in the lovely desert scape of Tucson, AZ at the University of Arizona. Sunday was a fantastic day of training, followed by three days of outstanding presentations from member institutions and sponsors. Rittman Mead wanted to show how important the higher education community is to us, so along with me, we had our CEO-Jon Mead, our CTO-Jordan Meyer, and our US Managing Director-Charles Elliott. If our AirBnB had ears, it would have heard several solutions to the problems of the world as well as discussions of the fleeting athleticism of days gone past. But alas, that will have to wait.

While at the conference, we had a multitude of great conversations with member institutions and there were a few themes that stuck out to us with regard to common issues and questions from our higher education friends. I will talk a little bit about each one below with some context on how Rittman Mead is the right fit to be partners in addressing some big questions out there.

Legacy Investment vs BI tool Diversification (or both)

One theme that was evident from hour one was the influx of Tableau in the higher education community. Rittman Mead is known for being the leader in the Oracle Business Intelligence thought and consulting space and we very much love the OBIEE community. With that said, we have, like all BI practitioners, seen the rapid rise of Tableau within departments and lately as an enterprise solution. It would be silly for the OBIEE community to close their eyes and pretend that it isn’t happening. There are great capabilities coming out of Oracle with Data Visualization but the fact is, people have been buying Tableau for a few years and Tableau footprints exist within organizations. This is a challenge that isn't going away.

Analytics Modernization Approaches

We had a ton of conversations about how to include newer technologies in institutions’ business intelligence and data warehousing footprints. There is clearly a desire to see how big data technologies like Hadoop, data science topics like the R statistical modeling language, and messaging services like Kafka could positively impact higher education organizations. Understanding how you may eliminate batch loads, predict student success, know if potential financial aid is not being used, know more about your students with analysis of student transactions with machine learning, and store more data with distributed architectures like Hadoop are all situations that are readily solvable. Rittman Mead can help you prioritize what will make the biggest value impact with a Modernization Assessment. We work with organizations to make good plans for implementation of modern technology at the right place and at the right time. If you want more info, please let us know.

Sometimes we need a little help from our friends

Members of HEDW need a different view or another set of eyes sometimes and the feedback we heard is that consulting services like ours can seem out of reach with budgets tighter than ever. That is why we recently announced the Rittman Mead Expert Service Desk. Each month, there are hours available to spend however you would like with Rittman Mead’s experts. Do you have a mini project that never seems to get done? Do you need help with a value proposition for a project or upgrade? Did production just go down and you can’t seem to figure it out? With Expert Service desk, you have the full Rittman Mead support model at your fingertips. Let us know if you might want a little help from your friends at Rittman Mead.

To wrap up

Things are a changing and sometimes it is tough to keep up with all of the moving parts. Rittman Mead is proud to be a champion of sharing new approaches and technologies to our communities. Spending time this week with our higher education friends is proof more that our time spent sharing is well worth it. There are great possibilities out there and we look forward to sharing them throughout the year and at HEDW 2018 in Oregon!

Analysing the Panama Papers with Oracle Big Data Spatial and Graph

January 31, 2017 | 3:45 pm – 4:15 pm | Room 103

This practical example of using the tool will give attendees a clear idea of the functionality of the tool and how it could be used within their own organisation. If Oracle Database 12cR2 on-premise is available by the time of this presentation, then its new property graph capabilities will also be covered here. The presentation will be based on a paper published on OTN: https://community.oracle.com/docs/DOC-1006400


Kafka’s Role in Implementing Oracle’s Big Data Reference Architecture on the Big Data Appliance

February 1, 2017 | 2:20 pm – 3:10 pm | Room 102

Big Data … Big Mess? Everyone wants Big Data, but without a good platform design up front there is the risk of a mess of point-to-point feeds. The solution to this is Apache Kafka, which enables stream or batch consumption of the data by multiple consumers. Implemented as part of Oracle’s Big Data Architecture on the Big Data Appliance, it acts as a data bus for the enterprise to both the data reservoir and discovery lab. This presentation will introduce the basics of Kafka, and explain how it fits within the Big Data Architecture. We’ll then see it used with Oracle GoldenGate to stream data into the data reservoir, as well as ad hoc population of discovery lab environments and microservices such as Flume, HBase, and Elasticsearch.

(Still) No Silver Bullets: OBIEE 12c Performance in the Real World

February 2, 2017 | 1:30 pm – 2:20 pm | Room 203

Are you involved in the design and development of OBIEE systems and want to know the best way to go about ensuring good performance? Maybe you’ve an existing OBIEE system with performance “challenges” that you need to diagnose? This presentation looks at the practical elements of diagnosing the causes of performance issues in OBIEE, and discusses good practices to observe when developing new systems. It includes discussion of OBIEE 12c and with additional emphasis on analysis of Usage Tracking data for the accurate profiling and diagnosis of issues. Why this would appeal to the audience: – Method-R time profiling technique applied to the OBIEE nqquery.log – Large number of the community use OBIEE, many will have their own performance horror stories; fewer will have done a deep dive into analysing the time profile of long-running requests – Performance “right practices” will help those less familiar with performant OBIEE designs, and may prompt debate from those more experienced. As presented previously at OOW, OUGF, UKOUG, OUG Scotland, and POUG. Newly updated for OBIEE 12c. * Video: http://ritt.md/silver-bullets-video* Slides: http://ritt.md/silver-bullets-slides
