Configuring Java Logging for the SQL Engine Server
Java logging can be configured by placing a logging configuration file named ddlog.properties in the directory specified by the Schema Map option. The simple way to create one of these is to make a copy of the ddlog.properties file, which is located in your driver installation directory, in the install_dir/Sample/Example subdirectory.
