Optionally, you can set the following environment variables to improve the load performance:
SSAUDBPARALLELLOAD=<Integer>
SSAUDBSEQUENCES=Yes
IBM DB2 UDB prevents parallel loading when you load a table. To allow parallel loading, configure the SSAUDBPARALLELLOAD environment variable to a higher value that indicates the number of allowed parallel loads. A value of 999999 indicates unlimited parallel loads.
By default, IBM DB2 UDB does not use sequences. Set the SSAUDBSEQUENCES environment variable to Yes to use sequences.
