How does the communication happen between PMO & the ADRDSSU load module occur?
What are the performance concerns to ADRDSSU when PMO is active/when PMO is
The PMO DFDSS exit identifies the data set being processed, and then determines if there is a hash table for that
data set. If there is, the hash table is rebuilt later. Since this is proprietary code, there is not much more I can say.
PMO is only involved with the data set identification, so the impact on DFDSS is negligible. We have never had any customer performance concerns
with this area of the product.
