In previous posts I gave the steps required to install Oracle R Enterprise on your Database server and your client machine.
One of the steps that I gave was the initial set of Database privileges that the DB needed to give to the RQUSER. The RQUSER is a little bit like the SCOTT/TIGER schema in the Oracle Database. Setting up the RQUSER as part of the installation process allows you to test that you can (more...)
There are many different ways for you to connect to a database using R. You can setup an RODBC connection, use RJDBC, use Oracle R Enterprise (ORE), etc. But if you are an Oracle user you will want to be able to connect to your Oracle databases and be able to access the data as quickly as possible.
The problem with RODBC and RJDBC connections is that they are really designed to process small amounts (more...)
The headline articles of Oracle Magazine for July/August 2000 were on business intelligence, architectures for BI and how companies like NetFlix m drug-store.com and health insurances companies are using BI to better understand their customers.
Other articles included:

In my previous two blog posts (Part-A and Part-B) I detailed 4 steps for how you can install ORE on your servers and on your client machines.
I also mentioned a possible issue you may encounter if you try to install ORE on a Windows server. This blog post will look at this issue and how you can workaround it and get ORE installed.
The problem occurs when I when to install the (more...)
This is the second part of a two part blog post on installing ORE.
In reality there are 3 blog posts on installing ORE. The third and next blog post will be on a particular issue you might encounter on a Windows server and how you can over come the issue.
In the previous blog post I outlined the steps needed to install ORE on the database server and on the client machine. Click here (more...)
This blog post will look at how you can go about installing ORE in your environment.
The install involves a 4 steps. The first step is the install on the Oracle Database server. The second step involves the install on your client machine. The third steps involves creating a schema for ORE. The fourth steps is connecting to the database using ORE.
In this Part A blog post I will cover the first two steps (more...)
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...)
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...)
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 188.8.131.52
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...)
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...)
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...)
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?
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...)
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 184.108.40.206.
Check out the full announcement here.
Make sure you have a full backup of your ODM (more...)
Back at the end of January Oracle finally go round to releasing the updated version of the Oracle BigDataLite virtual machine. Check out my previous blog post of this.
Yesterday (27th March) I say on Facebook that a new updated versions of the BigDataLite VM was released. I must have missed the tweet and other publicity on this somewhere :-(
This is a great VM that allows you to play with the various Big Data (more...)
