Setting Default Sort Performance Options
Sorting large data sets can be one of the most time-consuming operations performed during batch processing, so setting appropriate sort performance options can have a significant impact on the performance of your jobs. Sort performance options control memory and disk utilization, allowing you to take full advantage of the available memory and disk capacity.
There are two places where you can configure sort performance settings. The first is in Spectrum Management Console. This is where you specify default sort performance options for your system. The second place is in dataflow stages that perform a sort. The Sorter stage, Read from File, Write to File, and all other stages that include a sort operation, contain sort performance options. When you specify sort performance option in a stage, you override the default sort performance options, choosing different settings to apply to individual stages in a dataflow.
This procedure describes how to set the default sort performance options for jobs run on your Spectrum Technology Platform server.
