The announcement highlighted some of the areas of improvement to be delivered by DB2 10 for z/OS, and at the top of that list, to no one's surprise, is performance. DB2 10 promises to deliver out-of-the-box savings by improving operational efficiencies ranging from 5% to 10% out-of-the-box CPU savings for traditional workloads and up to 20% out-of-the-box CPU savings for nontraditional workloads.
Other areas called out by IBM in the announcement include
- Improved business resiliency through scalability improvements and fewer outages (planned or unplanned).
- Schema evolution or data definition on demand as well as query performance manageability enhancements support improved availability.
- New features such as hash access, index include columns, inline large objects, parallel index updates, faster single row retrievals, work file in-memory, index list prefetch, 64-bit memory enhancements, use of the 1 MB page size of the System z10, buffer pools in memory, access path enhancements, member clustering for universal table spaces, efficient caching of dynamic SQL statements with literals, improved large object streaming, and SQL procedure language performance.
- Rapid application and warehouse deployment for business growth including improved concurrency for data access, data management, and data definition.
- The ability avoid an outage by adding active log data to a subsystem.
- Improved application and data warehousing support including temporal data, a 64 bit ODBC driver, currerntly committed locking, implicit casting or loose typing, timestamp with time zone, variable timestamp precision, moving sum, and moving average.
- Improvements to DB2's XML support including expanded pureXML, customer-driven performance and usability requirements, schema validation in the engine, binary XML exchange format, multiversioning, easy update of subparts of XML document, stored procedures, user-defined functions and triggers, XML index matching with date/timestamp, and a CHECK XML utility.
- Enhanced query and reporting facilities, including QMF V10 with over 140 new analytical functions, support for HTML, PDF, and Flash reports, and more.
If you are interested in the beta program, the pre-requisite for DB2 10 is z/OS V1.10 (5694-A01) or later running in 64 bit mode. More information about the DB2 10 beta program is available on IBM's web site.
No GA date for DB2 10 has been announced.
