IBM recently announced the DB2 11 for z/OS Early Support Program (ESP). Selected ESP participants are able to utilize the next version of DB2 prior to its general availability. Contact your IBM representative for details.
The DB2 11 ESP begins on March 8, 2013. For more, read the announcement letter. This is from the overview:
"DB2 10 delivered strong CPU savings that drove great value for IBM clients. DB2 11 follows up with even more CPU savings and improved performance. Compared to DB2 10, DB2 11 clients may achieve up to 5 percent out-of-the-box CPU savings for various traditional online transaction processing (OLTP), heavy INSERT, and SAP workloads. Select query workloads may see even more benefits, with up to 20 to 30 percent CPU savings. Read intensive OLTP workloads may see up to 10 percent CPU savings with DB2 11. Decompressing data is much faster using DB2 11, with significant performance improvements, delivering up to 15 percent CPU savings when running the queries against compressed tables. Deep integration between DB2 and System z continues to bring value.
"Additional RUNSTATS and LOAD workloads can now take advantage of zIIP engines, driving faster LOAD processing, improved performance, and CPU savings. With IBM zEnterprise EC12 (zEC12) and DB2 11, you can achieve additional CPU reductions through the use of pageable large (1 MB) pages and Flash Express, as well as the support of 2 GB pages."
