Range-partitioned table spaces typically house the largest tables in a DB2 environment. But what really is PBR RPN and why should it matter to me? This article explains the reasons behind this development effort, the issues RPN addresses, the benefits and use cases and also gives advice on its exploitation. Consequently, DB2 for z/OS must continue to evolve to ensure such large amounts of data can be managed in an efficient manner with minimal or no application impact.Ī significant step forward in this regard is the introduction in DB2 12 for z/OS of a major new feature called “PBR RPN” which transforms the management of range-partitioned table spaces. Haakon Roberts, DB2 for z/OS Development Introduction.ĭB2 tables continue to grow in size and these days it is not unusual to encounter tables containing tens of billions of rows.
