Oracle Data Visualization Desktop – now available

Accessing the R datasets in ORE and SQL

When you install R you also get a set of pre-compiled datasets. These are great for trying out many of the features that are available with R and all the new packages that are being produced on an almost daily basis.

The exact list of data sets available will depend on the version of R that you are using.

To get the list of available data sets in R you can run the following.

Experiments with Elastic’s Graph Tool

Elastic announced their Graph tool at ElastiCON 2016 (see presentation here). It’s part of the forthcoming X-Pack which bundles Graph along with other helper tools such as Shield and Marvel. Graph itself is two things; an extension of Elasticsearch’s capabilities, enabling the user to explore how items indexed in Elasticsearch are related, and a plugin for Kibana that acts as an optional front-end for this new functionality.

Contemplating Upgrading to OBIEE 12c?

Where You Are Now

NewImage
OBIEE 12c has been out for some time, and it seems like most folks are delaying upgrading to OBIEE 12c until the very last minute. Or at least until Oracle decides to put out another major version change of OBIEE, which is understandable. You’ve already spent time and money and devoted hundreds of resource hours to system monitoring, maintenance, testing, and development. Maybe you’ve invested in staff training to try to maximize (more...)

Data Integration Tips: Oracle Data Integrator 12c Passwords

Hey everyone, it’s Sunday night and we have just enough time for another Data Integration Tip from Rittman Mead. This one has originated from many years of Oracle Data Integrator experience – and several lost passwords. Let me start first by stating there is never any blame placed when a password is lost, forgotten, or just never stored away in a safe place. It happens more often than you might wish to think! Unfortunately, there is (more...)

Are you worried about what to do now that Discoverer is almost out of support

Hello everyone
Like me, if you are a big user of Discoverer, you would have been alarmed at the news a few years ago that Oracle was dropping the tool.

Well, once I got over my alarm I started to think about how my clients could maximize their use of the at times millions of dollars of investment.

Oracle Corporation’s statement of direction implies that they will not force you off of Discoverer and (more...)

Oracle Advanced Analytics in the Oracle Cloud

You have heard about the cloud? Right? Even the Oracle Cloud?

If you haven't, then maybe we need to look at how you can learn more about the Oracle Cloud.

Over the past while, and in the past few weeks in particular, Oracle has been advertising about how you can get a trail Oracle cloud service setup for FREE. Well it is free for one month when you set it up on the Oracle website (more...)

Rittman Mead at Collaborate 16: Data Integration Focus

It’s that time of year again when Oracle technologists from around the world gather in Las Vegas, NV to teach, learn, and, of course, network with their peers. The Collaborate conference, running for 10 years now, has been a collaboration, if you will, between the Independent Oracle Users Group (IOUG), Oracle Applications Users Group (OAUG) and Quest International Users Group (Quest), making it one of the largest user group conferences in the world.

ChitChat: The Importance of BI Integrations

A user’s workflow shouldn’t change to accommodate a new tool. A new tool should fill a gap in the current workflow and help streamline the user’s process. An application without a clearly defined scope eventually overlaps with existing solutions, creating confusion and distress among users. It takes both time and effort to clarify the appropriate situations to use the application, reconcile different use cases and approaches, and resolve incorrect uses. We designed ChitChat with appropriate (more...)

New OTN Article – OBIEE Performance Analytics : Analysing the Impact of Suboptimal Design

Configuring RStudio Server for Oracle R Enterprise

In this blog post I will show you the configurations that are necessary for RStudio Server to work with Oracle R Enterprise on your Oracle Database server. In theory if you have just installed ORE and then RStudio Server, everything should work, but if you encounter any issues then check out the following.

Before I get started make sure to check out my previous blog posts on installing R Studio Server. The first blog post (more...)

Installing RStudio Server on an (Oracle) Linux server

In a previous blog post I showed how you can install and get started with using RStudio on a server by using RStudio Server. My previous post showed how you could do that on the Oracle BigDataLite VM. On this VM everything was nicely scripted and set up for you. But when it comes to installing it on a different server, well things can be a bit different.

The purpose of this blog post is (more...)

The Importance of BI Documentation

Why Is BI Documentation Important?

Business intelligence systems come with a lot of extra information. Even beautifully constructed analyses have piles of background information and histories. Administrators might often have memos and updates that they’d like share with analysts. Sales figures might have anomalies that need further explanation. But OBIEE does not currently have any options for BI Documentation inside the dashboard.

Let’s say a BI user for a cell phone distribution company is viewing a report (more...)

Installing RStudio Server on Oracle BigDataLite VM

A very popular tool for data scientists is RStudio. This tool allows you to interactively work with your R code, view the R console, the graphs and charts you create, manage the various objects and data frames you create, as well shaving easy access to the R help documentation. Basically it is a core everyday tool.

The typical approach is to have RStudio installed on your desktop or laptop. What this really means is that (more...)

ASO Slice Clears – How Many Members?

Essbase developers have had the ability to (comparatively) easily clear portions of our ASO cubes since version 11.1.1, getting away from fiddly methods involving manually contra-ing existing data via reports and rules files, making incremental loads substantially easier.

Along with the official documentation in the TechRef and DBAG, there are a number of excellent posts already out there that explain this process and how to effect “slice clears” in detail (here and here (more...)

Issue in using EJB Actions in OBIEE 11.1.1.9

Use OBIEE to Achieve Your GOOOALS!!! – A Presentation for GaOUG

Background

A few months before the start of the 2014 World Cup, Jon Mead, Rittman Mead’s CEO, asked me to come up with a way to showcase our strengths and skills while leveraging the excitement generated by the World Cup. With this in mind, my colleague Pete Tamisin and I decided to create our own game-tracking page for World Cup matches, similar to the ones you see on popular sports websites like ESPN and CBSSports, (more...)
