Prerequisites and Maintenance for IBM Db2 Analytics Accelerator for z/OS, V7

Db2 Analytics Accelerator V7.5.6 provides the following main enhancements and improvements:

  • Enhancements of IBM Integrated Synchronization (InSync)
    • Schema change support (add or alter column), now at production level (no longer as "technical preview")
    • Enhanced certificate management, e.g. transfer and activate new ones, remove old ones
    • Improved serviceability and messaging
  • Enhancements for Accelerator on Z
    • Ability to collect System Activity Reports (SAR) for additional diagnostics
    • Query performance and system stability improvements by using direct I/O mechanisms
    • JSON configuration enhancements: Ability to limit the maximum size of the temporary workspace on a disk
    • Enhancements related to query acceleration and performance
      • Option to block recursive queries from being routed to the Accelerator
      • Masked column support
        • Tables with masked columns can now be fully added, loaded, or replicated to an accelerator. Before this maintenance level, masked columns were omitted and only non-masked columns could be added, loaded, or replicated to an accelerator. 
        • Queries referencing the masked columns can be routed to an accelerator if the masked columns are not referenced in the outermost SELECT statement of the query.
        • This enhancement requires installation of the PTF UI74917 for Db2 for z/OS APAR PH33061
