WebSphere MQ for z/OS V7.1 extends the availability and opportunity for removing affinities between applications and queue managers to new classes of MQ applications. Shared Message Data Sets (SMDS) are an alternative to DB2 BLOB tables for storing large messages on shared queues. Message payload may be offloaded to an SMDS at message queue PUT (MQPUT) time and retrieved as required by MQGET. An SMDS offloaded message can be accessed with faster response time and reduced cpu than those offloaded to DB2 BLOBs. This session looks at how WebSphere MQ for z/OS exploits the unique features available to z/OS - sysplex and coupling facility - to provide you with the highest level of availability for your messages. We will first look at traditional shared queue support before taking an in-depth look at Shared Message Data Sets and the advantages this can bring. Paul S. Dennis ; IBM Corporation
