Changes in BI Server Cache Behaviour in OBIEE 12c : OBIS_REFRESH_CACHE

The OBIEE BI Server cache can be a great way of providing a performance boost to response times for end users – so long as it’s implemented carefully. Done wrong, and you’re papering over the cracks and heading for doom; done right, and it’s the ‘icing on the cake’. You can read more about how to use it properly here, and watch a video I did about it here. In this article we’ll see (more...)

Under the Covers of OBIEE 12c Configuration with sysdig

OBIEE 12c has changed quite a lot in how it manages configuration. In OBIEE 11g configuration was based around system MBeans and the biee-domain.xml as the master copy of settings – and if you updated a configuration directly that was centrally managed, it would get reverted back. Now in OBIEE 12c configuration can be managed directly in text files again – but also through EM still (not to mention WLST). Confused? Yep, I (more...)

Contemplating Upgrading to OBIEE 12c?

Where You Are Now

NewImage
OBIEE 12c has been out for some time, and it seems like most folks are delaying upgrading to OBIEE 12c until the very last minute. Or at least until Oracle decides to put out another major version change of OBIEE, which is understandable. You’ve already spent time and money and devoted hundreds of resource hours to system monitoring, maintenance, testing, and development. Maybe you’ve invested in staff training to try to maximize (more...)

ChitChat: The Importance of BI Integrations

A user’s workflow shouldn’t change to accommodate a new tool. A new tool should fill a gap in the current workflow and help streamline the user’s process. An application without a clearly defined scope eventually overlaps with existing solutions, creating confusion and distress among users. It takes both time and effort to clarify the appropriate situations to use the application, reconcile different use cases and approaches, and resolve incorrect uses. We designed ChitChat with appropriate (more...)

Install and configure OBIEE 12c

Oracle BI 12c has been released for some time now. There are a few changes in the way it is installed compared to the previous 11g releases. This post is about installing and configuring OBIEE 12c with detailed step-by-step instructions(Linux x86-64 in this case).

 

You can start with downloading the media from OTN :

1. Download and install JDK8(at least 1.8.0_40)

2. Download and install Weblogic Server

fmw_12.2.1.0.0_infrastructure_Disk1_1of1. (more...)

New beginning

Happy New Year everyone. I wish you a prosperous 2015!

Time is passing by too fast. I had a dynamic 2014 with a couple of interesting projects. It’s not time to recap now but it is definitely time to refresh my blog.

For me with the new year comes the new beginning too. I switched from contracting to permanent job because I’ve always wanted to work for an Oracle partner in the UK with big (more...)

OBIEE automatic redirect to a Dashboard via mod_rewrite

Normally end users would like to have a simple URL access for Oracle Business Intelligence Enterprise Edition (OBIEE) 11g like http://webhost:7777 and than to be automatically redirected to their Dashboard, instead of typing endless complex URL's.

Assuming you have following standard implementation of an OBIEE environment which contains an Oracle HTTP Server (OHS) configured with mod_wl_ohs to be proxied to point to your WebLogic Server hosting OBIEE and an OBIEE Server, you can simply use (more...)

Purging corrupted OBIEE web catalog users

Sometimes it can happen that user profiles within a web catalog become corrupted for any number of reasons. In order for these user profiles to be correctly re-initialized, there's more to be done than just drop /users/JohnDoe from the web catalog.

All in all there are three distinct places which need to be cleaned:
  • /users/JohnDoe
  • /system/users/123456
  • /system/acocuntids/987654
This is really important since especially the third place contains the translation between the userid and the effective (more...)

Working around opatch – Prerequisite check "CheckSystemSpace" failed.

I recently ran into the situation where the primary mount for a Linux tech account running an OBI install was just way too small to get OBIEE 11.1.1.7.140114 through.
Prerequisite check "CheckSystemSpace" failed.
The details are:
Required amount of space(17499.766MB) is not available.
So with a bit of hacking I got around it by displacing the ./patch_storage directory and forcing opatch to stop doing a file system check (basically no (more...)

How-To: File hunt for OBIEE GUI changes

Among the questions I receive and that frequently come up on OTN, treated in blog posts etc. are questions pertaining to: How do I change a part of the GUI of OBIEE? Now in this post you'll find the answer to that specific question, but the point here today isn't simply to say "do X in Y", but rather "how do you get to know that you need to change X in Y?".

Excel VS BI in Financial Analysis: why the fight was over before it started

by Victor Fagundo

The argument over why Businesses should abandon Excel in favor of more structured tools has been raging for as long as I have had more than a casual exposure to Oracle products. From the standpoint of an IT user Excel appears to be a simplistic, flat-file-based, error-prone (more...)

Conditional Formatting of Calculated Items in OBIEE 11g

By Victor Fagundo

Calculated items in OBIEE Pivot tables can be very useful in certain reporting circumstances, either for ease of development, or to meet specific report requirements. While calculated items in OBIEE are easy, and flexible, they do have one important drawback: they take on the data and display (more...)

Business Intelligence Enterprise Edition & Applications

Not too long ago Oracle released Oracle Business Intelligence Enterprise Edition (OBIEE – 11.1.1.7.0) and Oracle Business Intelligence Applications (OBIA – 11.1.1.7.1) on version 11g. As you might know, OBIA is basicly an addition to the OBIEE where you get

(First off, sorry Mike, I'm hoping this will break my writer's block...)

On Friday I was asked to look at a report that wasn't returning all of the data. Sample:
Year/Month  Total Sales Total Sales (YAGO)
------------------------------------------
01/31/2013 $1,000,000 $900,000
03/31/2013 $950,000
For reference, YAGO is "Year Ago."

Notice anything funny there?

Yeah, February is missing. The (OBIEE) report has a filter on Jan, Feb and Mar of 2013. But it wasn't showing up. I confirmed via manual SQL (hah!) that there was (YAGO) data in there for February. Any ideas?

I immediately suspected one of two (more...)

Book Review: OBIEE 11g: A Hands-On Tutorial

Since a few months, a new book has appeared in the Oracle Business Intelligence landscape. This is good news for the Oracle BI community because it gives us a new middle of communication and discovery. The book provides a more comprehensive approach that articles or blogs and gives a privileged and direct access with the [...]

A chart is worth a thousand words – only when it’s used appropriately (Part 2)

Charts are informative and widely adopted in Business Intelligence. However, sometime they are misused and generates no business insights but confusion. In my last post, we've discussed about Line Chart and Pie Chart. Today let's continue the same topic by examining map, gauge and Trellis.

Map Chart

Maps have been used to visualize information since the early phase of human civilization. Now in the recent years, thanks to the digitalization of maps more and more quantitative analysis of location related information can be performed on top of map. Furthermore, with powerful spatial systems such as Oracle Spatial, the business (more...)

A chart is worth a thousand words – only when it’s used appropriately (Part 1)

People love charts and graphs. They are intuitive, less intimidating (compare with big fat spreadsheet) and more informative. However, every now and then, I've seen people force data into unsuitable charts, not for revealing business insight purpose but for just having some color and graph on their BI reports. In those cases charts provide no value add but duplication or confusion, in terms of analysis. In this post, I will examine a few OBIEE chart types which I believe are important but sometime not used in the most appropriate way by end users.

Line Chart

Lines work better than any other means to make (more...)

OBIEE install avoid RTD license problems

If you are not going to use RTD (Real Time Decisions) uncheck the box during installation:

OBIEE 11116 repository on MS-SQL I

We had to do a POC on some MS-SQL data. Instead of bringing an extra Oracle DB we used an existing MS-SQL instance.

1. Create a repository database:

We called ours “Repositories” Winking smile

2. Enable case-sensitive collation

ALTER DATABASE Repositories COLLATE Latin1_General_CS_AS

3. Enable Row versioning

ALTER DATABASE Repositories SET READ_COMMITTED_SNAPSHOT ON

 

4. Allow TCP/IP access to the database:

(Bounce the service if you changed it!)

4b. If you have a firewall running check if the ms-sql port is open (1433 for a default instance)

5. Create a user (fi: REP_OWN)

6. make  the default database repositories:
