Abstract: Recent IMS maintenance has added a capability for IMS to verify the reorganization numbers of HALDB partitions. This enhancement has improved the integrity of HALDB databases. The maintenance was delivered as a result of APARs PQ97357 for IMS Version 9 and PQ97356 for IMS Version 8. This paper explains the need for the function, how it operates, and how you can implement it. It also provides guidance on avoiding the potential database integrity exposure before you apply this maintenance. Finally, it provides background information about how IMS uses reorganization numbers with HALDB partitions.
