For best performance in a batch environment, DPV Flat is recommended with a Large memory model. Running with the Flat Large memory model will require about 50MB of additional virtual memory for the processing run. For CICS and IMS processing, Finalist forces a Pico memory model.
For LACSLink, a Medium memory model is recommended if your system can provide the 250MB virtual memory requirement. A Small memory model will require only 35MB of virtual storage with a minimal performance loss. Ultra-Small will require only 1MB of virtual storage, but has significant performance loss.
For SuiteLink, a Large memory model will require 50MB of storage and provide excellent performance results. A Medium memory model will require only 7MB of storage and provides good performance results. Small and Ultra-Small will require only 1MB of storage, but have significant performance loss.
