Using SparkSQL and Pandas to Import Data into Hive and Big Data Discovery

Using SparkSQL and Pandas to Import Data into Hive and Big Data Discovery

Big Data Discovery [https://www.oracle.com/big-data/big-data-discovery/index.html] (BDD) is a great tool for exploring, transforming, and visualising data stored in your organisation’s Data Reservoir. I presented a workshop on it at a recent conference [https://speakerdeck.com/rmoff/unlock-the-value-in-your-big-data-reservoir-using-oracle-big-data-discovery-and-oracle-big-data-spatial-and-graph] , and got an interesting question from

OBIEE 12c – Extended Subject Areas (XSA) and the Data Set Service

One of the big changes in OBIEE 12c for end users is the ability to upload their own data sets and start analysing them directly, without needing to go through the traditional data provisioning and modelling process and associated leadtimes. The implementation of this is one of the big architectural

Changes in BI Server Cache Behaviour in OBIEE 12c : OBIS_REFRESH_CACHE

The OBIEE BI Server cache can be a great way of providing a performance boost to response times for end users - so long as it's implemented carefully. Done wrong, and you're papering over the cracks and heading for doom; done right, and it's

#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

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 [https://docs.oracle.com/middleware/11119/biee/BIESG/configsettings.htm#BIESG1643] and the biee-domain.xml as the master copy of settings - and if you updated a configuration directly

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.

Data Integration Tips: Oracle Data Integrator 12c Password

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 a lost 12c password. Let me start first by stating there is never any blame placed

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

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

I’m pleased to have recently had my first article published on the Oracle Technology Network (OTN) [http://www.oracle.com/technetwork/index.html]. You can read it in its full splendour and glory(!) over there [https://community.oracle.com/docs/DOC-993649], but I thought I’d give a bit

The Importance of BI Documentation

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

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,

One of the first steps to improve OBIEE performance is to determine why it is slow. That may sound obvious—can’t fix it if you don’t know what you’re fixing, right? Unfortunately, the “Drunk Man anti-method [http://www.brendangregg.com/methodology.html]”, in which we merrily stumble
