Knowage Suite 6.x CE

I found Spago BI version 5.1, that is about two years ago. It was a Complete Open Source BI Sotution, the only one there is, they said. They were proud of it!. And I was waiting for 5.3 to start a series of posts as they announced amazing changes.

On may 4th 2017, @SpagoBI anounced they were starting a #spagobirevolution. The same company (Engineering Group) did an extreme makeover to XU experince and released a Comunity Edition (CE) and an Enterprise Edition (EE) with a Knowage Brand.

What I have seen is that the CE is an interesting product, somewhat crippled as important functionality like scheduling and MDX calculated fields and more are excluded, but lets hope its cockpit designer, metadata, models and widgets, deliver a promising alternative for OS BI data exploration.

Knowage has updated its documentation with instructions for windows, linux and DB migration scripts from 5.x [link].

Prerequisites: You’ll need Java JDK 1.8 and JAVA_HOME defined.

1. Download the Knowage Installer [download page]
   Knowage-6_2_0-CE-Installer-20180809.zip [2.8GB from knowage-suite.com]
   Knowage-6_2_0-RC-CE-Installer-Unix-20180509.zip [2.9GB from one server in ow2]
   Knowage-6_1_1-CE-Installer-Unix-20171213.zip [2.3GB]

   All-in-One-Knowage-6.0.0_RC_CE_20170429.zip [798mb]
2. Open a Terminal, create a folder, unzip its content:

   mkdir Knowage6
   cd Knowage6
   cp ../dowloads/Knowage-6_2_0-RC-CE-Installer-Unix-20190509.zip Knowage.zip
   unzip Knowage
   chmod 777 Knowage-6_2_0-RC-CE-Installer-Unix-20180509.sh
   ./Knowage-6_2_0-RC-CE-Installer-Unix-20180509.sh

3. Run the installer, it will:

   a. Open a welcome dialog. click Next.
   b. Ask if you accept the license agreement. Do it so and click Next.
   c. Ask for your preference on a charting library. Accept the default and click Next.
   d. Ask for six modules to be installed. If all are selected, Click Next.
   e. Select a destination folder. I selected HOME$/knowage6 it will create a Knowage-Server-CE folder.
   f. It will ask for your MySql credentials: jdbc:mysql://localhost:3306/, user and password.
      Version 6.1.1 contains MariaDB files, I used my existing version without problems.
      It said that two schemas: kwowage-ce and foodmart-demo will be created

   The installer will extract the server, the .war files and update the database.
   In the final dialog unselect all and click finish to end the installer.

4. I modified the startup and shutdown scripts to set the correct path to java:

   cd $HOME/Knowage6/Knowage-Server-CE/bin
   gedit startup.sh
   [add your JRE path to the first line like:]
   export JRE_HOME="/usr/lib/jvm/java-8-openjdk-amd64"

   save your script and repeat for shutdown.sh

5. You might want to increase the session time out from the default 30 minutes.
   Then you should edit ./HOME$/Knowage6/Knowage-Server-CE/conf/web.xml

   <session-config>
     <session-timeout>90</session-timeout>
   </session-config>
   

6. If you used your MySql/MariaDB instance, you can delete three files:

   rm $HOME/Knowage6/Knowage-Server-CE/webapps/mariadb-10*

7. Start your tomcat server:

   cd $HOME/Knowage6/Knowage-Server-CE/bin/
   ./startup.sh
   

8. Start yor browser and set it to:

   http://localhost:8080/knowage

You will find examples on the left menu, enjoy.

If you have problems with the server you can check your ./logs folder.
