Install pre-requisites & Mondrian

\bin>mysql -u root -h localhost mysql>GRANT ALL PRIVILEGES ON *.* TO foodmart@localhost IDENTIFIED BY 'foodmart'; Query OK, 0 rows affected (0.06 sec) 3. Create tables and indexes,load the data, run sanity checks: For Linux mysql> source /mondrian-data/demo/mysql/foodmart.sql For Windows mysql> source c:\mondrian-data\demo\mysql\foodmart.sql mysql> commit; mysql> show tables;

NOTE: On Red Hat Linux(including Fedora) you must to delete the user created(foodmart) in phpmyadmin. Then you have to create new user in phpmyadmin, too.

2.4

Modify code For Windows and Linux: Before you load the data base, you have to modify the file "mondrian.jsp" located in TOMCAT_HOME\webapps\mondrian\WEB-INF\queries

Quick Tutorial for Datamart

For MySQL: select {[Measures].[Unit Sales], [Measures].[Store Cost], [Measures].[Store Sales]} on columns, {([Promotion Media].[All Media], [Product].[All Products])} ON rows from Sales where ([Time].[1997]) Test Query uses Mondrian OLAP For Access: select {[Measures].[Unit Sales], [Measures].[Store Cost], [Measures].[Store Sales]} on columns, {([Promotion Media].[All Media], [Product].[All Products])} ON rows from Sales where ([Time].[1997]) Test Query uses Mondrian OLAP

2.5

Install Driver for MySQL After you had installed Mondrian, loaded the database In Linux download the mysql's driver (mysql-connector-java-3.0.16-ga-bin.jar from /mysql-connector-java-3.0.16-ga ), and copy it in opt/lampp/lib/tomcat/common/lib In Windows download the mysql's driver (mysql-connector-java-3.0.16-ga-bin.jar from /mysql-connector-java-3.0.16-ga), and copy it in TOMCAT_HOME\commom\lib

Test Mondrian Sample 1.- Delete /mondrian from TOMCAT_HOME\work\Catalina\localhost 2.- Restart Xampp and Tomcat 3.- Hit http://localhost:8080/mondrian

2.7

Enable print and export to Excel and PDF When you load mondrian for first time, the print, set print and excel buttoms don't work, for make it work you must add the red lines in the file web.xml located in: TOMCAT_HOME\webapps\mondrian\WEB-INF.

Install Mondrian Plugin

3.1

Install Pre-requisites: Download and Install Eclipse version 3.x and the EMF&SDO version 2.x(required).

International Potato Center (CIP)...© 2006

Install Mondrian Plugin

14

Download and unzip the mondrian-schema.zip into Eclipse installation directory, this will install the plugin. Download it from http://research.cip.cgiar.org/docs/downloads/ or http://sourceforge.net/projects/jpivot or :\Install\Pre-requisites\Windows Start up eclipse and in the menu click on Help->About Eclipse Plattform->Plug-in Details. Mondrian Schema Editor Plugin must appear in the list of installed plugins.

3.2

Test Plugin The plugin is registered with the ".mondrian" file extension, this means you will have to rename TOMCAT_HOME\webapps\mondrian\WEB-INF\queries\Foodmart.xml into Foodmart.mondrian so Eclipse can associate the file with the plugin. If you prefere, download the file Foodmart.mondrian : http://research.cip.cgiar.org/docs/mondrian/FoodMart.mondrian
