When tsort or psort executes in sequential mode, it's called a total sort.
When tsort or psort executes in parallel mode, it's called a partition sort or a parallel sort.
When you combine a parallel sort with a sort merge collector, it's called a total sort.
Records processed by psort must be less than 32 KB in length (psort... prohibitive sort).
In the Sort stage:
The default "Sort Utility = DataStage" option leads to the tsort operator.
The "Sort Utility = Unix" option leads to the psort operator. You can find "psort -sorter unix" in the OSH script.
