Definition

The number of the program run is used to distinguish between different instances of the same program, which can come into existence as a consequence of parallel processing on table level. The original program for the multiplication gets numbe "00", while the created parallel instances are numbered in sequence starting with "01".

Use

This parameter can have a big impact on performance.

If the update phase of conversion of some table takes very long time (for example more than 50% of the total time of the conversion) then it probably makes sense to set this value higher (for example 16 or 20). On the other hand each additional job uses system resources, which are limited, and therefore cannot be used for other tasks.

If the runtime of the update phase of the conversion of some table is not very long (that is it does not run for a substantial part of the conversion) then probably setting this value higher will not make sense. The system resources will also not be left unused, as other processes will make use of them.
