A few months ago ODTUG announced their ODTUG Mobile Day in Utrecht, Netherlands and asked if I’d like to put forward an abstract for a presentation. Something that’s been on my mind for a while is the issues some of our customers have been reporting trying to run Oracle BI Mobile HD with the Good Mobile Device Management toolkit, so I thought this might be a good opportunity to look into the topic in more (more...)
The May/June 2015 edition of Oracle Magazine is now out, and my Business Intelligence article in this edition is on Oracle BI Cloud Service (BICS). In “Upload, Model, Analyze and Report” I focus on the “departmental power-user” use-case where someone with a small team wants to share data and dashboards with others in the department, is familiar with OBIEE but wants to get something up-and-running quickly without having to include IT or the formal development (more...)
In two previous posts this week I talk about a client request to offload part of their data warehouse top Hadoop, taking data from a source application and loading it into Hive tables on Hadoop for subsequent reporting-on by OBIEE11g. In the first post I talked about hosting the offloaded data warehouse elements on Cloudera Hadoop CDH5.3, and how I used Apache Hive and Apache HBase to support insert/update/delete activity to the fact and (more...)
Earlier in the week I blogged about a customer looking to offload part of the data warehouse platform to Hadoop, extracting data from a source system and then incrementally loading data into HBase and Hive before analysing it using OBIEE11g. One of the potential complications for this project was that the fact and dimension tables weren’t append-only; Hive and HDFS are generally considered write-once, read-many systems where data is inserted or appended into a file (more...)
Part III – There’s Something (Profitable) About Your Privacy
Why do so many companies hanker after apps? Smartphone apps, tablet apps, iOS apps, Android apps, app-this, app-that….
Leave aside for a moment the techno-pubescent excitement that accompanies the launch of every new technology (if you are not old enough to remember words like “client-server”, then “soa (more...)
Using HBase and Impala to Add Update and Delete Capability to Hive DW Tables, and Improve Query Response Times
One of our customers is looking to offload part of their data warehouse platform to Hadoop, extracting data out of a source system and loading it into Apache Hive tables for subsequent querying using OBIEE11g. One of the challenges that the project faces though is how to handle updates to dimensions (and in their case, fact table records) when HDFS and Hive are typically append-only filesystems; ideally writes to fact tables should only require (more...)
As you all probably know I’m a big fan of Oracle’s BI and Big Data products, but something I’ve been critical of is OBIEE11g’s lack of support for HiveServer2 connections to Hadoop clusters. OBIEE 126.96.36.199 supported Hive connections using the older HiveServer1 protocol, but recent versions of Cloudera CDH4 and CDH5 use the HiveServer2 protocol by default and OBIEE 188.8.131.52 wouldn’t connect to them; not unless you switched (more...)
It’s now the Saturday after the two Rittman Mead BI Forum 2015 events, last week in Atlanta, GA and the week before in Brighton, UK. Both events were a great success and I’d like to say thanks to the speakers, attendees, our friends at Oracle and my colleagues within Rittman Mead for making the two events so much fun. If you’re interested in taking a look at some photos from the two events, I’ve put (more...)
After over two years since the last major release of OBIEE, Oracle released version 184.108.40.206 in May 2015. You can find the installers here and documentation here. 220.127.116.11 is termed the “terminal release” of the 11g line, and the 12c version is already out in closed-beta. We’d expect to see patchsets for 11g to continue for some time covering bugs and any security issues, but for new functionality in (more...)
Alternatives to using ROracle would be RODBC, RJDBC and DBI. So you could use one of these to connect to the database.
In this post I want to show (more...)
Oracle Documentation for 18.104.22.168 is here.
And most importantly the 3 "New Features Guides" in detail:
I’ve been using Oracle Big Data Discovery for a couple of months now, and one of the sessions I’m delivering at this week’s Rittman Mead BI Forum 2015 in Atlanta is on Big Data Discovery Examples from the Field, co-presented with Tim Vlamis from Vlamis Software. Tim is going to concentrate on a data analysis and visualization example using a financial/trading dataset, and I’m going to look at at some of the trickier, or less (more...)
It’s the Monday before the Atlanta Rittman Mead BI Forum 2015, and delegates will start to arrive in Atlanta tomorrow and during the rest of the week. The first event in Brighton was excellent, and we’re hoping for something even better in Atlanta this week!

The Numbers Game Can be Very Misleading
According to the Internet Trends report of 2014, mobile internet advertising spend grew 47% (more...)
In this post I want to show you one way of taking a JSON file of data and loading it into your Oracle schema using ROracle. The JSON data will then be used to create a table in your schema. Yes you could use other methods to connect to the database and to create the table. But ROracle is by far the fastest method of connecting, selecting and processing data.
1. Necessary R Packages
With the release of SQL Developer 4.1 we also get a number of new features with Oracle Data Miner (ODMr). These include:
- Data Source node can now include data sources that contain JSON data, generating JSON schema and has a JSON viewer
- Create Table can now create data in JSON
- JSON Query Node allows you to view, query and process JSON data, combine it with relational data, generate sub-group by, and nested columns to (more...)
Earlier today (4th May) SQL Developer 4.1 was released :-)
For those of you who use the Oracle Data Miner tool (that is part of SQL Developer) you will need to upgrade your repository. The following steps will walk you through the process.
This article talks about a method to handle this (more...)
