I followed the instructions to "Create objects for TPC-C" and it is taking a very long time to load for a DB2 database.
Replace your current CTPCC_DB2CLI.dll with the one attached to this solution. By default it is located in the 'C:\Program Files\Quest Software\Benchmark Factory for Databases 5.5\bin' directory. Make sure BMF is closed when you replace the file.
Waiting for fix to be released in a future release of BMF for database.
