Oracle GoldenGate, MySQL and Flume

Back in September Mark blogged about Oracle GoldenGate (OGG) and HDFS . In this short followup post I’m going to look at configuring the OGG Big Data Adapter for Flume, to trickle feed blog posts and comments from our site to HDFS. If you haven’t done so already, I strongly recommend you read through Mark’s previous post, as it explains in detail how the OGG BD Adapter works.  Just like Hive and HDFS, Flume isn’t (more...)

OBIEE 11g query tracking mechanism


We had a requirement of tracking a query fired from OBIEE. This was to help us find out the Analysis that consume the most database resources.
It is possible that some user might be selecting a huge date range resulting in the problem at the database. So the trouble in this case might be (more...)

Installing OBIEE 11g Client tool on Windows 8


OBIEE 11g client tool is not certified with Windows 8. 
The certification matrix for OBIEE version 11.1.1.7.0+ is in the following location and it does not include Windows 8.

This blog talks about a way to to install admin tool on Windows 8 machine.


We can download both the 64 bit and 32 bit windows installer for client tool from OBIEE portal.

Lifting the Lid on OBIEE Internals with Linux Diagnostics Tools

There comes the point in any sufficiently complex or difficult problem diagnosis that the log files in OBIEE alone are not sufficient for building up a complete picture of what’s going on. Even with the debug/trace data that Presentation Services and other components can be configured precisely to write you’re sometimes just left having to guess what is going on inside the black box of each of the OBIEE system components.

Here we’re going to (more...)

New Oracle Big Data Quick-Start Packages from Rittman Mead

Many organisations using Oracle’s business intelligence and data warehousing tools are now looking to extend their capabilities using “big data” technologies. Customers running their data warehouses on Oracle Databases are now looking to use Hadoop to extend their storage capacity whilst offloading initial data loading and ETL to this complementary platform; other customers are using Hadoop and Oracle’s Big Data Appliance to add new capabilities around unstructured and sensor data analysis, all at considerably lower-cost (more...)

RM BI Forum 2015 : Justification Letters for Employers

(Thanks to Christian Berg @Nephentur for the suggestion, and acknowledgements to ODTUG KScope for the original idea – our favourite conference after the BI Forum)

The Rittman Mead BI Forum 2015 promises to be our best BI Forum yet, with fantastic speakers at each event, keynotes and guest speakers from Oracle and John Foreman, author of the bestselling book “Data Smart”, a data visualisation challenge and an optional one-day masterclass on delivering Oracle’s new Information (more...)

OBIEE nqcmd Tidbits

nqcmd is the ODBC command line tool that always has, and hopefully always will, shipped with OBIEE. It enables you to manually fire queries directly at the BI Server, rather than through the usual way of Presentation Services generating Logical SQL and sending it to BI Server. This can be useful in several cases:

  1. Automated cache purging, by sending one of the SAPurge[…] ODBC commands to the BI Server, usually done as part of a (more...)

Announcing the BI Forum 2015 Data Visualisation Challenge

The Rittman Mead BI Forum 2015 is running in Brighton from May 6th-8th 2015, and Atlanta from May 13th – 15th 2015. At this year’s events we’re introducing our first “data visualization challenge”, open to all attendees and with the dataset and scenario open from now until the start of each event. Using Oracle Business Intelligence 11g and any plugins or graphics libraries that embed and interact with OBIEE (full details and rules below), (more...)

Instrumenting OBIEE Database Connections For Improved Performance Diagnostics

Nearly four years ago I wrote a blog post entitled “Instrumenting OBIEE – The Final Chapter”. With hindsight, that title suffix (“The Final Chapter”) may have been a tad presumptuous and naïve of me (or perhaps I can just pretend to be ironic now and go for a five-part-trilogy style approach…). Back then OBIEE 11g had only just been released (who remembers 11.1.1.3 in all its buggy-glory?), and in (more...)

OBIEE 11g dashboard pages outside of a dashboard


We had a strange requirement. The user did not want the dashboard to be published and he hated the fact that he had to expand the dashboard to see the pages in it.

Since the requirement is strange so will be the solution.

One option is to create the shortcut of each page and then hide the dashboard.  This option is recommended but will lead to creation of a shortcut for each page.

Might need to use Tunneling with Discoverer 11g

I have noticed a few instances recently of Discoverer 11g Plus failing to open or taking an awful long time to open. In both of the cases where this has been reported to me by my clients, changing the plus communication protocol from Default to Tunneling did the trick.

To enable tunneling for use with Discoverer Plus, use this workflow:

  1. Launch Enterprise Manager using something like: http://server.domain.com:7002/em
  2. Enter your Username and Password. Username (more...)

3 way switch in OBIEE 11g


While we all know about using conditions on sections in a dashboard, and while we all have used presentation variables to show or hide a report using these conditions, this blog talks about a process to use conditions on sections to implement a 3 way decision rather than just a boolean (true/false) decision.


Lets say that we have to show one section based on one value of a presentation variable, another based on another value (more...)

More on the Rittman Mead BI Forum 2015 Masterclass : “Delivering the Oracle Big Data and Information Management Reference Architecture”

Each year at the Rittman Mead BI Forum we host an optional one-day masterclass before the event opens properly on Wednesday evening, with guest speakers over the year including Kurt Wolff, Kevin McGinley and last year, Cloudera’s Lars George. This year I’m particularly excited that together with Jordan Meyer, our Head of R&D, I’ll be presenting the masterclass on the topic of “Delivering the Oracle Big Data and Information Management Reference Architecture”.

Automatic Analytics is So main stream. Not something new.

Everyone is doing advanced analytics. Right? Hmm

Everyone is talking about advanced analytics? Yes that is true.

Everyone is an expert in advanced analytics? This is so not true. Watch out for these Great Pretenders. You know what I mean! You know who I mean! Maybe you know some of them already? If not, watch out for these Great Pretenders!!!

Some people are going around talking about data mining, predictive analytics, advanced analytics, machine learning (more...)

An Introduction to Analysing ODI Runtime Data Through Elasticsearch and Kibana 4

An important part of working with ODI is analysing the performance when it runs, and identifying steps that might be inefficient as well as variations in runtime against a baseline trend. The Operator tool in ODI itself is great for digging down into individual sessions and load plan executions, but for broader analysis we need a different approach. We also need to make sure we keep the data available for trend analysis, as it’s often the (more...)

Over the past couple of months Oracle has been releasing some EA (Early Adopter) versions of a new tool that is currently called SQL Command Line.

The team behind this new tool is the SQL Developer development team and they have been working on creating a new command line SQL tool that is based on some of the technology that is included in SQL Developer.
