• Batch Resource Recovery Service (RRS) support allows batch programs to use MQSeries with coordinated commit. It also provides for a full two phase commit for batch programs accessing DB2 as well as IMS DB, where today's Batch Attach from DB2 does not support coordinated commit. And it also allows for work which captures data and propagates it to another system (DB2) to participate in the 2-phase syncpoint process along with the IMS work, thus making sure that all the work is done or not done where it is all part of the same unit of recovery. Batch RRS support is also being utilized by the new IMS DataPropagator V3R1 which provides asynchronous, near real-time IMS-to-DB2 Propagation by taking advantage of the asynchronous messaging functions of the IBM MQSeries product. With this the operations and administration of an asynchronous propagation is simplified, easier to use, and less error-prone. This near real-time propagation would also offer improved performance and reliability, minimizing the impact on mission-critical IMS applications that are updating IMS DB data being propagated to DB2.
