I have tried to use the DB2 as the database, and start my jazz application by connecting to the database, but get the following error message:

java.lang.RuntimeException: CRJAZ1238I Jazz has detected another server process is connected to the repository database location "db2:/localhost:60000/JAZZ". The server must not be running when running repotools data commands. Check that only one process is connecting to the database
