    * PROBLEM DESCRIPTION: Here is the list of problems            *
    *                      addressed :                             *
    *                                                              *
    *                      - Performance optimization is required  *
    *                      to reduce the CPU consumption           *
    *                      resulting from the Db2ZAI Distributed   *
    *                      connection control (DCC) and SQL        *
    *                      optimization processes.                 *
    *                                                              *
    *                      - Permissions to the Liberty logs in    *
    *                      Db2ZAI are changed from 640 to 644 so   *
    *                      that users other than the owner or      *

    *                      set to COMMA in the target Db2          *
    *                      subsystem, Db2ZAI user interface users  *
    *                      might receive SQLCODE -104.             *

    * RECOMMENDATION: Apply corrective PTF when available          *
    ****************************************************************
    Here is a summary of the reported Db2ZAI issues:
    
    - To reduce the CPU requirement from Db2ZAI, the following
    areas can be optimized.
       a. Scorecard process when DCC alerts are generated.
       b. Model creation in SQL optimization
    - Currently Db2ZAI Liberty logs are using the default
    attributes for permission (640), however,  this is too
    restrictive, and prevents users from accessing the logs.
    - When the DSNHDECP DECIMAL option is set to COMMA in the
    target Db2 subsystem, Db2ZAI user interface users may receive
    SQLCODE -104 while viewing the SQL optimization dashboard.
    
    Additional keywords:
    
    DB2AIV1R6/K SQLCODE104
    

Problem conclusion

  • - SQL Optimization and DCC process are optimized.
    - The permission attribute for the Liberty logs is set to
    644.
    - The SQL optimization dashboard process is updated to support
    COMMA for the DSNHDECP DECIMAL option.
