The onpload database can reside on any database server on your network. In addition, any onpload utility can use the onpload database as long as the onpload utility can access the database server that contains the onpload database. In contrast, the onpload utility must run on the same computer as the database server that contains the target database. Логика процесса To populate the onpload database with the table mapping information (similar to control files in Oracle), SQL scripts are used. These scripts are generated according to the target table structures.
