Starting the simulation function

About this task

To start the simulation function, perform the following steps:

Procedure

  1. Start the IBM® DB2® Buffer Pool Analyzer by double-clicking the icon on your Windows desktop, or use the Start push button on the taskbar to start this client application.

    If you are using Db2 Performance Expert, click Tools > Buffer Pool Analysis for z/OS on the menu bar, or click the Opens the Buffer Pool Analysis for z/OS window toolbar button.

    The Db2 Buffer Pool Analyzer - z/OS® main window is displayed.

  2. On the menu bar, click File > Start Simulation. Alternatively, click the Starts simulating buffer pools toolbar button.
    To directly simulate Object Placement results right-click the object placement result file and select Simulate....
    Note: Simulate... passes the object placement recommendations to the simulation function. If the files match, the object placement output is used, otherwise an error message is displayed.

    The Open dialog box is displayed. You use this dialog box to select and open a trace data file that contains the buffer pool activity data you want to use for the simulation.

    Several sample buffer pool trace data files (*.trace) are delivered with Buffer Pool Analyzer in the …\samples\simulation folder. You can use them to become familiar with this function.

  3. Continue with Selecting and opening a trace data file.
