Strategy's default driver for DB2 requires specific User privileges in order to connect to the database.
It's all explained here: KB19382: Information regarding package creation and binding for the MicroStrategy ODBC Driver for DB2 Wire Protocol .
If you don't have access to a DBA or cannot get the privileges added to your Database account, you can still use JDBC to setup the connection.
The following article explains how to connect to Databases using JDBC: KB250923: Connecting to Databases using JDBC Drivers in MicroStrategy 10.x.
Regarding IBM DB2, you can download the JDBC driver from the IBM download site
