Non Standard SQL in BIP 11g – Dynamic query implementation


SQL query is often used as a data source in BIP and often we have a requirement in which we have to use one table when the user selects a certain value in a parameter and select a totally different table when the user selects another value in the parameter. While we have discussed a method to do this using pipelined functions in http://obiee-oracledb.blogspot.com.au/2011/07/performance-enhancing-drug-called-table.html, this blog post talks about a (more...)

Increasing width of Multiselect in OBIEE 10g


I was recently involved in a project implementation on OBIEE 10g. The dashboard had a multiselect and the values in the prompt were huge. The standard width of the multiselect was making the user uncomfortable since a large part of the value was hidden due to the small size of the multiselect. This blog talks about a method to fix this problem.

Let me first show you how the multiselect looked.

Book Review: Predictive Analytics Using Oracle Data Miner

My friend and colleague, ACE Director Brendan Tierney, has recently published the reference book Predictive Analytics Using Oracle Data Miner. It is the first comprehensive book on the subject matter. The book is primarily aimed at the Oracle Data Scientist/Data Miner. The other target audience are Oracle developers who implement the data mining models created by the Data Scientists in their applications, e.g. OBIEE. Some of the areas covered are also relevant for Oracle (more...)

OUG Mexico

We (Gorcan, Glen, Debra and I) arrived into Mexico around 10pm and had a few minutes wait for our local user group contact to meet us. They had arranged transportation to our hotel.

Oracle Data Integrator (ODI) Architecture Review Service.

There are various tell-tale signs that something is not quite right with your Oracle Data Integrator implementation. Does your ODI architecture suffer from the following symptoms?

  • The ETL seems to take forever
  • Some data flows take more than 30 minutes
  • Your developers take ages to implement new data flows or change existing mappings
  • The ETL breaks at least once a week
  • No meaningful and consistent set of naming standards and coding conventions has been implemented.
  • (more...)

OUG Costa Rica

After the OUG Panama conference we arrived later that night in San Jose the capitol of Costa Rica. The whole emigration, luggage pick up and customs was the smoothest experiences I have ever experienced at an airport. All was done in a matter of minutes. All the booths for emigration and customs was open and staffed. When was the last time you have ever seen this before. It was a very positive start to our (more...)

OUG Panama

The OTN Tour of Latin America has come to an end and I was very lucky to have been a part of Northern part of the tour.

Over the last two years there have been significant changes and improvements in the various Big Data frameworks. With the release of Yarn (Hadoop 2.0) the most popular of these platforms now allows you to run mixed workloads. Gone are the days when Hadoop was only good for (more...)

Privilege to see hidden objects in OBIEE 11g


My client wanted to hide some of the reports from the users and release them at a later date. The however wanted a set of users to have the privilege to see hidden objects. Let us see the process to achieve this objective.

While we can directly assign the privilege to the users, it is far better to do the following.

1. Create a power user group
2. Create a new role
3. Assign the (more...)

Smart Tables in OBIEE 11g


This article introduces the concept of Smart Tables in OBIEE. I call them 'Smart' because these tables have the ability to produce different data on the fly. These can morph themselves according to the user requirement. Smart Tables also make the data model dynamic in nature as a Smart Table can change characteristics on the fly. Let me now explain the procedure of implementing Smart Tables.
Objective: We will create 2 tables in the database. (more...)

Skipping schedule in BI Publisher 11g


This is an awesome feature in BI Publisher 11g but I do not hear a lot of noise about it so let me create some.
I'm talking about Event triggers in BI Publisher 11g. Using event triggers, we can conditionally stop the delivery of a report. We will see the process of skipping schedules in this article.

Steps:
  1.   Create a data model for a BIP report.
    • a. Define a dataset
    • b. Define a Event (more...)

Drill-able charts in OBIEE 11g


This is a discovery more than a solution. OBIEE 11g lets us use Hierarchical column as dimensional attributes for charts.

Using hierarchical columns in chart enables us to create drill-able charts. The default view can be the top level view and the user can then drill to a more granular view in the chart on the fly.

Consider the following Analysis. I have dragged hierarchical time dimension column and a measure column. I have created (more...)

Formatting levels of a hierarchical column in OBIEE 11g


I had a requirement to indent the levels in a hierarchical column. The solution isn't really innovative but I thought of sharing this because finding the option can become a treasure hunt.

The objective is to attain the following.

















Note that the values in every consecutive level is indented compared to the previous level.

Steps:

1. Drag a hierarchical column, expand its levels and select Hierarchy Level Properties as shown below.








2. You will land (more...)

Tokenizing a String : Using Regular Expressions

In my previous blog post I gave some PL/SQL that performed the tokenising of a string. Check out this blog post here.

Thanks also to the people who sent me links examples of how to tokenise a string using the MODEL clause. Yes there are lots of examples of this out there on the interest.

While performing the various searches on the internet I did come across some examples of using Regular Expressions to extract (more...)
