To access a DB2 9.5 or DB2 10 server, you need the JDBC driver consisting of the following jar files: db2jcc.jar, db2jcc_license_cu.jar, db2jcc_javax.jar. The required files are located in the java subdirectory of your DB2 installation.
When starting, the PPM server outputs the exact versions of the database and the JDBC driver. In the log file or on the command line, messages like this are displayed:
...Establishing connection between user UMG_EN and jdbc:db2://ppmdbsrv:50001/PPM...
...Database version used: SQL09013.
...JDBC driver used: IBM DB2 JDBC Universal Driver Architecture (3.4.65).
