  • 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
