DB2 11 for z/OS:

GA – general availability for ESP partners: March 8, 2013, announcement - 5615-DB2           

  • CPU reductions, performance improvements and system efficiency
    • Compared to use of DB2 10, you may achieve up to 5% out-of-the-box CPU savings for many traditional OLTP, heavy INSERT, and SAP workloads.
    • Compared to use of DB2 10, you may also achieve up to 20 to 30% out-of-the-box CPU savings for select query workloads. These performance improvements along with use of IBM DB2 Analytics Accelerator for z/OS , can further enable significant query acceleration and potential cost savings.
    • New SQL PL ARRAY support may bring up to an additional 10% CPU savings for OLTP workloads with higher read-to-write ratios
    • You may see additional performance and CPU savings by taking advantage of additional enhancements, including DPSI performance improvements and suppress null indexes.
    • Additional optimizer enhancements for distinct, group by, and sparse index support bring performance improvements across a wide variety of queries.
    • Cost effective archiving of warm and cold data with easy access to both within a single query
    • Using pageable large (1 MB) pages and Flash Express (with IBM zEnterprise EC12, zEC12)
    • Enabling support of 2 GB pages (with IBM zEnterprise EC12, zEC12)
  • Improved-data sharing performance
    • Data sharing clients may see performance improvements from a 2x to 5x more efficient index structure modification and from full LRSN spin avoidance.
  • Improved utility performance and additional zIIP eligible workload
    • Inline statistics gathering enhancements greatly reduces the need for RUNSTATS which can reduce resource consumption.
    • DB2 Utilities now offer more zIIP eligible workload for RUNSTATS and LOAD and faster LOAD processing for improved performance and CPU savings. Additional REORG enhancements minimize DBA workload with automated mapping tables and improved PBG handling.
    • Improve productivity and performance through REORG avoidance and auto index pseudo delete cleanup.
  • Availability and reliability
    • SWITCH phase reduction and improved drain processing in online REORG deliver additional availability improvements.
    • The need for planned outages is significantly reduced with online data repartitioning capabilities, including support for REORG, REBALANCE, SHRLEVEL, CHANGE, and online ALTER LIMITKEY.
    • With extended relative byte address (RBA) and log record sequence number (LRSN) addressing support you can avoid many manual recovery actions that can potentially cause extended outages.
    • Improved backup manageability enables even faster recovery.
    • Improved cloning capabilities support automatic VCAT name translation for system-level backup.
  • Other enhancements
    • Deploy real-time scoring directly within the transaction when used in conjunction with IBM SPSS offering.
    • Together with IBM DB2 Analytics Accelerator for z/OS and System z , user can efficiently colocate OLTP and data warehouse as one integrated workload in real time.
    • DB2 QMF , a separately priced feature of DB2 for z/OS , has also been enhanced to include improved analysis, forecasting, reporting, and presentation capabilities, as well as better storage management, supporting greater analytics on business data.
    • Improvements in XML, temporal support, and SQL PL deliver even more capabilities for application developers.
    • Various SQL enhancements including support for array data types and global variables, make it easier for application developers
  • Migration:
    • With the new application compatibility feature, migration plans no longer have to wait for applications to make SQL or XML changes before leveraging new DB2 features.
    • Simpler catalog migration helps your business get the value of DB2 11 faster.
    • DB2 11 for z/OS is upwardly compatible with earlier releases of DB2 for z/OS . Migration with full fallback protection is available for customers running on DB2 10. Existing customers should ensure they are successfully running on DB2 10 for z/OS (NFM) before migrating to DB2 11.

DB2 10 for z/OS:

GA – general availability: 22. Oct. 2010, Announcement.

  • Reduced CPU usage:
    • DB2 CPU savings of up to 5% – 10% for traditional workloads and up to 20% for specific workloads, when compared to running the same workloads on DB2 9. Customers moving from DB2 9 should expect the same CPU times for utilities, while customers moving from DB2 V8 will see CPU reductions up to 20%.
    • DB2 reduces its CPU usage by optimizing processor times and memory access, leveraging the latest processor improvements, larger amounts of memory, and z/OS enhancements.
    • Improved scalability and virtual storage constraint relief can add to the savings.
