Processing through the Db2 engine
In some cases, Optim™ High Performance Unload will unload data by using the Db2® engine. The DB2 YES or DB2 FORCE option must be specified. If DB2 NO is specified in such a case, the unload processing is stopped with error messages.
When an unload is done using the Db2 engine, such unloads can only be done from a live database and not from a Db2 backup image.
