    * RECOMMENDATION: Apply the provided PTF.                      *
    ****************************************************************
    IBM Z Performance and Capacity Analytics does not include
    the ability to simulate a workload allowing for a change
    in the number and type of processors along with an expected
    growth in workload.
    

Problem conclusion

Temporary fix

Comments

  • A new forecasting mechanism is provided - Workload Simulation.
    This enables you to explore What-If scenarios of increasing
    the workload and/or changing the hardware using an iterative
    simulation modeler which can model how the system will respond
    to the workload.
    
    The following objects are added:
    
    TABLES:
    CP_CPU_SCENARIO_S
    CP_CPU_LPAR_S
    CP_CPU_WKLD_TX_S
    CP_CPU_WKLD_PROC_S
    
    VIEWS:
    CP_CPU_WKLD_SV
    CP_CPU_LPAR_SV
    CP_CPU_WSIM_SV

    New Cognos reports are provided to view the output of
    workload simulations. Reports located in folder:
