Preview of Maria Colgan, and Andrew Bond/Stewart Bryson Sessions at RM BI Forum 2014

We’ve got a great selection of presentations at the two upcoming Rittman Mead BI Forum 2014 events in Brighton and Atlanta, including sessions on Endeca, TimesTen, OBIEE (of course), ODI, GoldenGate, Essbase and Big Data (full timetable for both events here). Two of the sessions I’m particularly looking forward to though are ones by Maria Colgan, product manager for the new In-Memory Option for Oracle Database, and another by Andrew Bond and Stewart Bryson, (more...)

Oracle R Enterprise and Oracle 12c

A few of weeks ago we had the release of Oracle R Enterprise (ORE).

There has been some posts on the R/ORE on the Oracle discussion forums about installing ORE on Oracle 12c.

It turns out that the only way to install ORE on an Oracle 12c database is if you do a traditional install. What this means is that you do not have a CDB and PDBs configuration of Oracle 12c.

I'll assume that (more...)

Oracle Advanced Analytics and Oracle Fusion Apps

At a recent Oracle User Group conference, I was part of a round table discussion on Apps and BI. Unfortunately most of the questions were focused on Apps and the new Fusion Applications from Oracle. I mentioned that there was data mining functionality (using the Oracle Advanced Analytics Option) built into the Fusion Apps, it seems to come as a surprise to the Apps people. They were not aware of this built in functionality and (more...)

Oracle 11.2g install on OLE 6.x

This notes are really just a reminder to myself of the typical "issues" that I encounter every time I do a new install of OEL 6.x and 11.2.0.4

These notes are in addition to the excellent installation instructions given by oracle-base.com: oel install, DB 11.2.0.x install

The notes listed below are just a reminder to myself of things that I seem to always have to look (more...)

How to find out a table type in Hive Metastore.

| Apr 10, 2014

Hi All

As Hive metastore is getting into the center of nervous system for the different type of  SQL engines like Shark and Impala. It getting equally difficult to distinguish type of table created in Hive metastore. Eg. if we create a impala table using impala shell you will see the same table on hive prompt and vice versa. See the below example

Oracle Text and Oracle Data Miner

This blog post is a follow up to comment on a previous blog post and to some emails.

Basically the people are asking about some messages they get when they open the Oracle Data Miner tool, that is part of SQL Developer.

If you are just using the SQL and PL/SQL functions in the database then you do not have to worried about Oracle Text. You will receive no warning message.

But if you use (more...)

Set up https (SSL) for Weblogic and OBIEE

I have been blogging about the integration between Oracle eBS and Oracle BI EE. Apart from the integration, there are are few assumptions: Oracle eBS is installed Oracle BI is installed Oracle eBS and Oracle BI are compatible with each other (http vs. https) All necessary Oracle eBS patches are installed R11 check R12 included […]

The ORE Packages

If you are interested in using ORE or just to get an idea of what does ORE give you that does not already exist in one of the other R packages then the table below lists the packages that come as part of ORE.

Before you can use then you will need to load these into your workspace. To do this you can issue the following command from the R prompt or from the prompt (more...)

I’m honoured to have been accepted to speak at this year’s Rittman Mead BI Forum, the sixth year of this expert-level conference that draws some of the best Oracle BI/DW minds together from around the world. It’s running May 8th-9th in Brighton, and May 15-16th in Atlanta, with an optional masterclass from Cloudera’s Lars George the day before the conference itself at each venue.

My first visit to the BI Forum was in 2009 (more...)

Data Integration Tips: ODI 12c – Varchar2 (CHAR or BYTE)

Continuing with our Data Integration Tips series, here’s one that applies to both Oracle Data Integrator 11g and 12c. This “tip” was actually discovered as a part of a larger issue involving GoldenGate, Oracle Datapump, and ODI. Maybe a future post will dive deeper into those challenges, but here I’m going to focus just on the ODI bit.

The Scenario

During our setup of GoldenGate and ODI, it was discovered that the source and target (more...)

Visualising OBIEE DMS metrics with Graphite

Assuming you have set up obi-metrics-agent and collectl as described in my previous post, you have a wealth of data at your disposal for graphing and exploring in Graphite, including:

  • OS (CPU, disk, network, memory)
  • OBIEE’s metrics
  • Metrics about DMS itself
  • Carbon (Graphite’s data collector agent) metrics

In this post I’ll show you some of the techniques we can use to put together a simple dashboard.

Building graphs

First off, let’s see how Graphite (more...)

Gartner 2014 Advanced Analytics Quadrant

The Gartner 2014 Advanced Analytics Quadrant is out now. Well it is if you can find it.

Some of the companies have put it up on their websites to promote their position.

For some reason Oracle hasn't and I wonder why?

Gartner Advanced Analytics MQ Feb2014

You can see that some typical technologies are missing from this, but this is to be expected. How much are companies really deploying these alternatives on real problems and in production. Perhaps the positioning (more...)

ODM Repository upgrade Issue with 4.0.1

An important announcement was made on the Oracle Data Mining discussion forum last night and I haven't seen anything on twitter about it yet (but maybe I missed it). It was about some ODM Repository migration issues that you might encounter with using ODM in SQL Developer 4.0.1 and using the Oracle Database 11.2.0.3.

Check out the full announcement here.

Make sure you have a full backup of your ODM (more...)

Built-In OBIEE Load Testing with nqcmd

nqcmd ships with all installations of OBIEE and includes some very useful hidden functionality – the ability to generate load tests against OBIEE. There are lots of ways of generating load against OBIEE, but most require third party tools of varying degrees of complexity to work with.

It’s easy to try this out. First set the OBIEE environment:  [I'm using SampleApp v309R2 as an example; your FMW_HOME path will vary]

How To Create External Hive Table on HBase

| Mar 28, 2014

Hi All,

While building a data flow for replacing one of the EDW’ workflow using Big Data technology stack , came across some interesting findings and issues.  Due to  UPSERT ( INSERT new records or UPDATE existing records depending) nature of data we had to use Hbase, but to expose the outbound feed we need to do some calculation on HBase and publish that to Hive as external. Even though conceptually , its easy to create an (more...)

Data Integration Tips: ODI 12c – Substitution API GUIDs

With the release of Oracle Data Integrator 12c and Oracle GoldenGate 12c still fresh in our minds, I thought I would start an ongoing series focused on Data Integration Tips – specifically around the latest version of Oracle’s data integration tools. The goal is to provide insight into some of the hidden, undocumented, or lesser known features of these products. Most of these tips and tricks will come from our experiences when solving challenges for (more...)
