Populating a Table in an Existing Table Space

If you are populating a table in an existing table space, it is usually better to have db2split use the existing partitioning map for the nodegroup, rather than create a new one. The reason is that db2split will create the best distribution for the table, but not necessarily for the table space. In this situation, you should use the db2gpmap program to obtain a copy of the partitioning map from the catalog partitioned database server and have db2split use this file to partition the data.
