PREDICTION_DETAILS function in Oracle

When building predictive models the data scientist can spend a large amount of time examining the models produced and how they work and perform on their hold out sample data sets. They do this to understand is the model gives a good general representation of the data and can identify/predict many different scenarios. When the "best" model has been selected then this is typically deployed is some sort of reporting environment, where a list is (more...)

#IHateYourFace, a BizIntel Love story

Sometimes love isn’t fair

A teenager, just emerging from an awkward growing phase drives a tendency to spew non sensical permutations of varying cringe worthy affections toward their love target.  The data points behind the intent are solid.  Let’s go Boolean now:

Intent of good = 1 ;

attracted to target = 1;

ability to provide for target = 1;

time available  = 1;

prior or current committed relationship = 0.

Under the Covers of OBIEE 12c Configuration with sysdig

OBIEE 12c has changed quite a lot in how it manages configuration. In OBIEE 11g configuration was based around system MBeans and the biee-domain.xml as the master copy of settings – and if you updated a configuration directly that was centrally managed, it would get reverted back. Now in OBIEE 12c configuration can be managed directly in text files again – but also through EM still (not to mention WLST). Confused? Yep, I (more...)

Data Integration Tips: ODI 12c – Who Changed My Table Names?

It’s Sunday night (well, technically Monday morning now), and we have just enough time for another one of my Data Integration Tips. This one, revolving around Oracle Data Integrator 12c, has been on my mind for some time now, so I figured we better just get it out there. Imagine this; you’ve upgraded from Oracle Data Integrator (ODI) 11g to ODI 12c and executed the first test Mapping. But hey…what happened to my C$ table (more...)

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...)

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...)
