Ramu,
Here is an extract from DFSORT manual about the HIPRMAX parameter. Note that memory object sorting is an exclusive feature of DFSORT.
The HIPRMAX parameter sets the maximum amount of Hiperspace to be used during a run. Hiperspace is a high-performance data space that resides in expanded storage, or in central storage for 64-bit real mode, and is backed by auxiliary storage (if necessary). Because I/O processing is reduced for Hipersorting, elapsed time, EXCP counts, and channel usage are also reduced.
Specifying HIPRMAX=OPTIMAL allows DFSORT to optimize the maximum amount of Hiperspace to be used during a run, subject to other system and concurrent Hipersorting and memory object sorting activity throughout the run. OPTIMAL specifies that DFSORT determines dynamically the maximum amount of Hiperspace to be used for Hipersorting.
Please note that not all features of DFSORT are supported by Syncsort.
