Usage Notes

If a transaction contains any record that exceeds the standard page size defined by the Temporary Storage Page Size DBS Control field, the RSG will allocate memory using the large page size. If the record exceeds the large page size, the entire transaction is spilled to disk.

Pages are not shared between transactions, so increasing the page size may cause a decrease in storage utilization efficiency.
