Installing DB2 Express-C on Windows
IBM makes available a free version of their flagship DB2 database called DB2 Express-C. It is a competitor to Oracle Express, Microsoft SQL Server Express and MySQL. It is ideal for a development environment or a small pilot project, and it can be updated to a fully supported licensed version at any time. Cognos 8 Business Intelligence supports reporting off this database and using it as the content store. This tutorial will step through the installation of DB2 Express-C on Windows.
Download DB2 Express-C from the IBM website: http://www-306.ibm.com/software/data/db2/express/download.html
Extract the files, and double click setup.exe to get started. On Windows Vista or Windows 2008 Server, right click the setup.exe and select ‘Run as Administrator’.
