Problem conclusion

  • Db2ZAI user interface and data services have been updated
    to support the certain JDBC properties such as security
    mechanism and encryption algorithm options.
    
    Below are the Db2ZAI SQL Optimization stored procedures
    that have been updated to resolve the lock escalation,
    high CPU consumption, and as well as support of simple
    model for host variable.
    
    DSNML.CREATE_OFNR_SIMPLE_MODELS
    DSNML.CREATE_PARA_MODELS
    DSNML.GET_CPU_TIME_REG_MODEL
    DSNML.GET_NEXT_ELIGIBLE_HV_MODEL
    DSNML.GET_NEXT_ELIGIBLE_OFNR_MODEL
    DSNML.INSERT_UI_METRICS
    
    Db2ZAI configuration script has been updated to prompt for
    user inputs on the ports.
