Here are some options you have with DB2 utilities and regular SQL:
1. To prevent logging of an SQL statement, alter the table to not logged initially, do the SQL, and run the script with auto-commit off. This will prevent logging, but make sure you commit at the end of the script (since auto-commit is off).
2. Use the COMMITCOUNT option during the import. If you set it to 1000 or so, then the logs will not fill up.
3. Do a LOAD with NONRECOVERABL option.
