3.Create user and give privileges
International Potato Center (CIP)...© 2006
Install pre-requisites & Mondrian
<MYSQL_HOME>\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:

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

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
<MYSQLCONNECTOR_HOME>/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
<MYSQLCONNECTOR_HOME>/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:

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

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

Create a simple cube
We're going to create a simple OLAP cube for passport data, for this we need to:
· Modify the source code of mondrian.jsp
· Create a schema for the OLAP model with Eclipse
For this example we're using a sample database of potato from CIP
