I wrote a while ago about converting Oracle’s superb OBIEE SampleApp from a VirtualBox image into an EC2-hosted instance. I’m pleased to announce that Oracle have agreed for us to make the image (AMI) on Amazon available publicly. This means that anyone who wants to run their own SampleApp v406 server on Amazon’s EC2 cloud service can do so.
Before getting to the juicy stuff there’s some important points to note about access (more...)
A question that I’ve noticed coming up a few times on the OBIEE OTN forums goes along the lines of “How can I find out who deleted a report from the Presentation Catalog?”. And whilst the BI Server’s Usage Tracking is superb for auditing who ran what report, we don’t by default have a way of seeing who deleted a report.

Kibana is a graphical front end for data held in ElasticSearch, which also provides the analytic capabilities. Previously we looked at where the data came from and exposing it through Hive, and then loading it into ElasticSearch. Here’s what we’ve built so far, the borders denoting what was covered in (more...)

This included blog hits from the Apache webserver log, tweets, and metadata from WordPress. Having got it into Hive I now need to get it into ElasticSearch as a pre-requisite for using Kibana to see how it holds up as a analysis tool or as a (more...)

What I wanted to do was visualise the data I’d brought in, looking for patterns and correlations. Obviously the de facto choice at our shop would (more...)
