Experience on my MicroStrategy Interviews being on both sides!

Writing a post after 2 long years. But not technical this time. Inspired by a couple of posts from MicroStrategy Guru of Gurus! Bryan Brandow and also coz of the interviews that I have been on both sides atleast for the past one year!

To me as far as an interview is concerned its just the first 5 minutes which is very important and how you actually set an interview in the direction which you want as an interviewee. Let me tell about an interview experience.. Basically it was an interview for 6  - 8 years of experience. Where the ask from the candidate was to be sharp in SQL skills, MicroStrategy Public Objects expertise and  good Schema objects exposure. Most of the folks hardly answered a simple Employee and Manager name scenario..

List out the Employee Names and Manager Names from the table?
List the names of employees who gets maximum salary in each department?
List out the duplicate records in a table and its count?

Employee Table
Emp ID Emp Name Manager ID Dept ID Salary
1 A 2 1 6000
2 B 3 1 7000
3 C 4 1 9000
4 D 5 2 15000
5 E 6 2 36000
6 F 1 2 5000
The moment most of the folks find it difficult to  answer simple SQL questions like above which are by standard popular interview questions in Datawarehousing and Business Intelligence industry. Many candidates barely fail to impress the technical capability of the interviewer. Yes though they might be very comfortable in MicroStrategy Schema objects or Public objects. The moment they fail to answer simple SQL questions its very hard for them to answer the questions in MicroStrategy!

Is SQL that important? 

Yes SQL is very important as far as BI Development is concerned just assume lets say if there is a business requirement given and your table is not available in the form which doesn't support report requirement. If you are not good in visualizing your report SQL it becomes very hard for you to solve the reporting requirement.

Cant it be learnt on the job? 

Yes it can be learnt on the job but, an experience over within 2 years its very important for developers to get good understanding on SQL and it becomes a bare minimum expectation to get your BI career forward. So if you ask me a question "Cant SQL be learnt on the job?" Yes it can be and it should be but make it a primary task within the first 2 years of your career. As it is very basic!

So folks make sure you get the SQL skills sharpened very early in your career. If not learn now. Right  now!

Second awareness in Datawarehousing and Business Intelligence (DWBI) concepts. Its very important for any MicroStategy developer to be at least aware of the DWBI concepts. Lets talk about my favorite interview question. 

Explain many to many relationship with an example and how would you solve it?

Many people find it very hard to explain even with a simple example.But what is actually expected in an interview is to explain this concept clearly with an example and say what would be the implications because of many to many relationships in reports and how to solve it. 

On the whole BI interviews are mainly about testing the understanding of the concepts and how you practically implement it. There could be several things you you might not have got opportunity to work with but whatever you say say it with good confidence and let the interviewer know that you have understood the stuff at least conceptually.

Hope you might be overwhelmed with lots of thoughts. Feel free to post your  comments and I will make sure to update the post if required.

Thresholds on Attributes now a reality from MicroStrategy 10.4!

Well well this is one of the most wanted feature out of the box for such a long time and now we have its ready available in v10.4. This is a freaky awesome feature. Now I'll smash those funky old BO developers who mocked at me back in 9.3.0 days with this feature. It took MicroStrategy such a long time to get this feature done. Never late. Thank you MicroStrategy. And here is how you do it.

This was made possible due to section made available for the microstrategy user community Idea Exchange. There are several other features available in latest releases just because an idea got posted in the exchange. I would recommend the community to post the ideas or any requirements which is not feasible to be done and it would enable MicroStrategy to work on it and get it available.

Just as you would apply thresholds using advanced thresholds editor and here is how you do it and see it on the reports.

Create a simple report with a few Attributes and a metric from the MicroStrategy Tutorial project and run the report. Now create a simple threshold in the report using the Advanced Thresholds Editor.

Now you should be able to see the thresholds in the report. Awesome isnt it!

MicroStrategy v10.0 New Feature - Derived Attributes

Hi All,

Today we are going to discuss one new feature from MicroStrategy v10.0 onwards called “DERIVED ATTRIBUTES”.

This is one functionality which I have been wanting to have desperately having worked with customers who always has requirements to Create an attribute / a conditional attributes which evaluates conditionsbetween two different tables.

Prior to v10.0 this was never possible until we have a Logical View or a Database view merging two tables in to a single one!

But now from v10.0 onwards there comes the most powerful but simple functionality called “DERIVED ATTRIBUTES”. We will see about this functionality in detail today.

First let’s see a basic scenario where we can employ this Derived Attributes. Say we have a report with the following objects.


Benefit Type


Employee cost

Say we have a requirement like to concat the values of Year and Benefit which are totally of different attribute hierarchy and we want it to be shown as an attribute. Prior to v9.4.1 it was not possible to achieve this functionality without a logical table or in the report level with the help of a derived metric.

However this can now be achieved through the help of DERIVED ATTRIBUTE from v10.

Steps to create a Derived Attribute.

Step 1: Create a dataset with the necessary objects

Step 2: Add the dataset in the reporting services document and create a derived attribute.

Step 3: Add the derived attribute to the grid in the document and run it.That’s it!



  • Now you can create an attribute from two different tables without having to create a logical table or a database view which is very simple and minimizes the schema design complexity.


Bottomline: This is one feature we wanted real bad and happy to see that its possible now in MicroStrategy atleast in the document. However there are few limitations now with Derived Attributes.

  • Must use a document in Web to create Derived Attribute.
  • Cannot edit a document in MicroStrategy developer when derived attribute is used.
  • Cannot create a derived attribute in a normal grid report.
Workaround for editing documents with Derived Attributes.

However we found one easy workaround to edit documents with Derived Attributes in the MicroStrategy Developer. Here is how you can do it...

Create a new Document

Then select File --> Open and then select the document with derived Attributes.

So with this you can easily make changes and edit the documents with Derived Attributes from Developer. Cool isnt it thanks to one of my peer developer Raja for finding this one out!

MicroStrategy Configuration Wizard Challenges with your new 10 Installation

Hi All,

For those who are trying to learn MicroStrategy with MicroStrategy 10 and Microsoft SQL Server as database, you are likely to get the following issue discussed below and today we will see how to resolve the same.

As of what I have seen with MicroStrategy 10 when using Configuration Wizard it does not detect the already available system DSN's in your machine. So you would need to configure the DSN with the help of the connectivity wizard.

And when I tried test connecting with connectivity wizard got the below error....

Connection test failed: Error in testing connection: Connect failed.
Error type: Odbc error. Odbc operation attempted: SQLDriverConnect.
[HY000:0: on SQLHANDLE] [MicroStrategy][ODBC SQL Sserver Wire Protocol
driver]General error. recvfrom failed:10054


SQL Server Browser service was not running. This service needs to be started when connecting to SQL Server named instances.

Resolution: Follow the steps given in the below article

Then post the above step I got the below error

Connection test failed: Error in testing the connection: Connect faild.
Error type: ODBC error. Odbc operation attempted: SQLDriverConnect.
[HY000:0: on SQLHANDLE] [MicroStrategy][ODBC SQL Sserver Wire Protocol
driver] General error. not TCP/IPServerName; InstanceName; SQLExpress
IsClustered; No; Version; 11.0.2100.60;;


The driver communicates using the TCP/IP network protocol which needs to be enabled for the database.

Resolution: Follow the steps given in the below article

Final challenge was very simple... it was just to configure the DSN connection with the MicroStrategy Connectivity Wizard. The thing here is that the MicroStrategy connectivity wizard expects the database username and password to configure the DSN connection successfully unlike the older approach for database hosted in the local machine with Windows/NT authentication.

To overcome this we would need to just provide the DB credentials for the Metadata.

Thats it we are done!

Bottom Line:

From MicroStrategy 10 onwards the local system DSN configured in the Intelligence Server machine is not detected by the configuration wizard and it requires MicroStrategy Connectivity Wizard to create the connection to the Metadata.

MicroStrategy 9.5.0 Compatibility Issue with SQL Server 2014

Hi All,

Recently I have been evaluating MicroStrategy 9.5.0 and its been a rebranding of MicroStrategy 9.4.1 with advanced security features and little functionalities.

Though Microsoft SQL Server 2014 is supported from MicroStrategy 9.4.1 onwards its does have a small compatibility issue with Microsoft SQL Server 2014.

I was running with MicroStrategy v9.5.0 and I get this error "Failed to create component ‘Server Administrator’; CoCreate Instance Returned 0x8007007E" after upgrading my database server from SQL Server 2012 to SQL Server 2014.

And it so happened after the upgrade to SQL Server 2014 MicroStrategy developer doesn't work when trying to log into the project source! and ends up in the below error.

Though MicroStrategy had already documented this issue in the TN below, the workaround suggested did not work out.

Troubleshooting steps:

Tried repairing the MicroStrategy Installation - Did not work out

Tried downloading the MicroStrategy setup file, reinstalled Microsoft Windows 7 and installed MicroStrategy 9.5.0 again - did not work out.

So far what I have seen both the above instances which din't work out when I had SQL Server 2014 installed on my PC. Then I installed SQL Server 2012 in my machine and then installed MicroStrategy v9.5.0 then Developer worked like a charm!


 I think there is some compatibility issue with SQL Server 2014 and MicroStrategy v9.5.0. 

My First MicroStrategy Product Limitation! - Projects with Partition Mapping not generating Optimized Report SQL

Hi All,

Is been a while since I have updated the blog! But this time its about my first MicroStrategy Product Limitation!

For some reason MicroStrategy Projects until v9.5.0 implemented with Partition Mapping do not generate optimized report SQL’s on certain reporting scenarios.
In one of our project environments we have projects implemented with and without Partition Mapping feature. We use Partition Mapping feature basically to overcome split DWH architecture.

Please refer the link for info. The issue was reproducible in v9.4.1 and v9.5.0 project environments. The attached document is reproduced from Customer Analysis Module.

It would be great if we could get a resolution for this! Happy Exploration.

Installing and Configuring MicroStrategy Web without IIS.

Hi All,

Today we are going to see a way to install MicroStrategy Web without IIS as a web server. IIS has some limitations if you are in one of the operating systems of windows mentioned below...

Microsoft Windows 7 Home Premium
Microsoft Windows 7 Home Basic
Microsoft Windows 7 Home Starter
Microsoft Windows Vista Home Premium
Microsoft Windows Vista Home Basic

Its basically a known product limitation as mentioned in the below link

However if you cannot upgrade to the higher versions of Windows. Here is one simple way to configure MicroStrategy Web with an opensource webserver named Apache Tomcat!

Here is how we can do it!

Download Apache 7.0 from the below link

Download JDK from the below link

Install both the software applications in the machine with the default machine installation.

To configure the JDK

·         From the Start menu, select Computer. The Computer dialog box opens.
·         Click System properties. The System dialog box opens.
·         Click Advanced system settings. The System Properties dialog box opens.
·          Click Environment Variables. The Environment Variables dialog box opens.
·         Under System Variables, click New to create a system variable. The New System Variable dialog box opens.

In the Variable Name field, type JAVA_HOME.

In the Variable Value field, type the path of the folder where you installed the JDK and click OK.

For example, if the fully qualified path to your JDK executable is C:\jdk1.6.0\bin\java.exe, the value of your JAVA_HOME variable is C:\jdk1.6.0.

If you have installed JDK under the Program Files folder, type Progra~1 when specifying the folder name in the Variable Value box

Assuming if you have installed JDK and its available in this location...

Paths to be set when a default installation of JDK is made.

C:\Program Files\Java\jdk1.6.0_19\bin;.;

C:\Program Files\Java\jdk1.6.0_19\lib;.;

C:\Program Files\Java\jdk1.6.0_19

 To configure Tomcat

·         From the Start menu, select Computer. The Computer dialog box opens.
·         Click System properties. The System dialog box opens.
·         Click Advanced system settings. The System Properties dialog box opens.
·         Click Environment Variables. The Environment Variables dialog box opens.
·         Under System Variables, click New to create a system variable. The New System Variable dialog box opens.
·         In the Variable Name field, type CATALINA_HOME
·         In the Variable Value field, specify the path of the folder where you installed Tomcat and click OK.

 For example, if you installed Tomcat directly to the C drive, the destination folder is C:\Tomcat.

Assuming if you have installed JDK and its available in this location... 

Your CATALINA_HOME should be set to : 

C:\Program Files (x86)\Apache Software Foundation\Tomcat_7.0

Locating the WAR file

·         The MicroStrategy Web Universal WAR file (MicroStrategy.war) is located in the path you specified when installing MicroStrategy Web Universal.
·         The default location when installing on 32-bit Windows environments is C:\Program Files\MicroStrategy\WebJSP.
·         The default location when installing on 64-bit Windows environments is C:\Program Files (x86)\MicroStrategy\WebJSP.

Deploying using Tomcat as a stand-alone Web container

·         To deploy MicroStrategy Web Universal or Mobile Server (JSP) using Tomcat as a stand-alone Web container
·         Copy the MicroStrategy.war file to the Tomcat\webapps folder.

To control access to the MicroStrategy Web Administrator and Mobile Server Administrator pages
·         In the Tomcat\conf folder, open the tomcat-users.xml file in a program that allows you to edit the file, such as Notepad.
·         Add the following tag and save the file:

<user name=”administrator” password=”administrator” roles=”admin”/>

Now stop and start the web server. That’s it you are done.

To configure MSTR Web Admin

To access MicroStrategy projects in Web.

Upon Successful configuration you should be able to see the version of the MicroStrategy web like below!

Issues faced and resolution with MicroStrategy 10.3

Once the war file is deployed and while logging into the MicroStrategy web admin console I got the below error http://localhost:8080/MicroStrategy/servlet/mstrWebAdmin

To overcome this issue we need to add entries to the couple of files under the Tomcat Configuration folder.

C:\Program Files\Apache Tomcat 7.0\conf\web.xml

        <web-resource-name>Protected Admin Area</web-resource-name>   
C:\Program Files\Apache Tomcat 7.0\conf\tomcat-users.xml
<user username="admin" password="admin" roles="manager-gui"/>
<user username="administrator" password="administrator" roles="manager,admin"/>
  <role rolename="manager"/>
  <role rolename="admin"/>
  <role rolename="manager-gui"/>
 <user username="tomcat" password="tomcat" roles="tomcat"/>
 <!-- <user username="both" password="<must-be-changed>" roles="tomcat,role1"/>
  <user username="role1" password="<must-be-changed>" roles="role1"/>

This should help you resolve this issue.
