This section explains the import group definitions when the multi-FES facility is used with the following partitioning methods:
The following figure shows an example of an import group definition when the multi-FES facility is used with the table-based partitioning method.

The following figure shows an example of an import group definition when the multi-FES facility is used with the key range-based partitioning method.

The following figure shows an example of an import group definition when the multi-FES facility is used with the hash partitioning method.

This example specifies the front-end servers as Datareplicator's target group for a parallel server's table where data is stored in individual servers by the hash partitioning method. By specifying the front-end servers, you can concurrently execute as many import processes as there are hash partitions; you can also reduce the communications overhead between the front-end and back-end servers, thereby reducing the overhead of the front-end servers. As a result, data linkage can be achieved more efficiently.
The following figure shows an example of an import group definition (when the front-end servers are specified with the hash partitioning method).
