Monitoring the health of an OBIEE system and diagnosing problems that may occur is a vital task for the system’s administrator and support staff. It’s one that at Rittman Mead we help customers with implementing themselves, and also provide as a managed service. In this article I am going to discuss the ELK stack, which fills a specific gap between the high-level monitoring and configuration functionality of Enterprise Manager 11g Fusion Middleware Control, and (more...)
First we asked what is the top most program (duh!!) but by how much and who are next in the list and so on.
Like most Data scientists who believe in the power of simple bar graphs we used our first “chart (more...)
Digging into the Boston public Dataset can reveal interesting and juicy facts.
Even though there is nothing juicy about Bed bugs but the data about Boston open cases for Bed bugs is quite interesting and worth looking at.
We uploaded the entire 50 mb data dump which is around 500K rows into the Data Visualizer and filtered the category for Bed Bugs. Splitting the date into its date hierarchy components we then plotted the month (more...)
rlwrap is a nice little wrapper in which you can invoke commandline utilities and get them to behave with full readline functionality just like you’d get at the bash prompt. For example, up/down arrow keys to move between commands, but also home/end to go to the start/finish of a line, and even ctrl-R to search through command history to rapidly find a command. It’s one of the standard config changes I’ll make to any system (more...)
Recently, here at InfoCaptor we started a small research on the subject of flags. We wanted to answer certain questions like what are the most frequently used colors across all country flags, what are the different patterns etc.
I am sure there are many of you who have never done a presentation at a conference and may not feel comfortable speaking in public. Well, I have a secret for you, despite the fact that I won the Best Speaker Award at Kscope14, I share your discomfort with speaking. What works for me, however, is that I (more...)
The following steps are what I did for installing 18.104.22.168 on Windows.
1. Download the Oracle installation ZIP files from the Oracle Downloads page.
2. Unzip the two 12c downloads files into the same directory.
3. Go to the newly created directory (it is probably called 'database') and you will find a file called setup.exe. Double click on this file.
After a couple of seconds you will see the Oracle Database (more...)
The innovation engine in the field of Business Intelligence and Data visualization tools , is certainly cranked up. Qlikview, Tableau and Tibco Spotfire introduced new category of Data Visualization term in the field of Business Intelligence.
Now every vendor offers some form of Data Discovery. Oracle is also working on something similar adding to their confusing mix of OBIEE stack.
Session or rather content-wise over these four days there are a couple of things to (more...)
Last week I had the great pleasure to attend Oracle Open World (OOW) for the first time, presenting No Silver Bullets – OBIEE Performance in the Real World at one of the ODTUG user group sessions on the Sunday. It was a blast, as the saying goes, but the week before OOW I was more nervous about the event itself than my presentation. Despite having been to smaller conferences before, OOW is vast in its (more...)
An updated version of the Oracle BigDataLite VM came out a couple of weeks ago, and as well as updating the core Cloudera CDH software to the latest release it also included Oracle Big Data SQL, the SQL access layer over Hadoop that I covered on the blog a few months ago (here and here). Big Data SQL takes the SmartScan technology from Exadata and extends it to Hadoop, presenting Hive tables (more...)
It’s the Saturday after Oracle Openworld 2014, and I’m now home from San Francisco and back in the UK. It’s been a great week as usual, with lots of product announcements and updates to the BI, DW and Big Data products we use on current projects. Here’s my take on what was announced this last week.
New Products Announced
From a BI and DW perspective, the most significant product announcements were around Hadoop and (more...)
As a first time OOW participant, when I arrived at Moscone this morning, the sheer size, grandeur and general over-the-top-ness hit me like a brick. Seeing it in pics and on youtube is one thing but experiencing first hand...wow. KScope back in June was a family party in comparison! Which isn't a bad thing by the way
For me, Sunday was all about getting my bearings and participating - (more...)
Lunch was...american. Very american. Think 50s-type diner. Think chili-chedder-hot-dog. Think fries. LOVE IT! (more...)
Just a short note to help publicise the Oracle Openworld 2014 EPM and BI Meetup that’s running next week, organised by Cameron Lackpour and Tim Tow from the ODTUG board.
This is an excellent opportunity for EPM and BI developers and customers to get together and network over drinks and food, and chat with members of the ODTUG board and maybe some of the EPM and BI product management team. It’s running at Piattini, located at (more...)
