To collect performance information on your application:

  o  Compile and link your application with the PCA
     Collector

  o  Issue the run command for your application. This
     causes the PCA Collector window to appear on your
     screen.

  o  In the Collector window, click on the File pull-down
     menu and choose New Datafile... to create a data
     file into which the Collector places performance
     data.

  o  Click on the Query Category button to see the
     Query Category menu, from which you can select the
     category of performance data you are interested in
     collecting.

  o  Click on the specific query category you are
     interested in. This causes the specific queries
     for that query category to be displayed in the
     query pane at the bottom half of the Collector main
     window.

  o  Click on the specific query related to the
     information you are intersted in collecting.

  o  Click on Collect, in the middle of the Collector
     main window.

  o  Invoke the Analyzer to see the results of your
     performance data collection.

  Note that you can collect information from only one
  query at a time. That is, you must do a separate
  collection run for each query you choose. You can
  append the results of multiple collection runs to one
  performance data file, allowing you to analyze all your
  performance data together.

  For more information on collecting and displaying
  performance information, refer to:

  o  The online help, which is context-sensitive. This
     means you can click on any object in a PCA window
     and get help on it by simultaneously pressing
     the Help key on your keyboard while you press and
     hold MB1 on the mouse.For more information on using
     online help, see the Help menu on any PCA screen.

     and Coverage Analyzer for OpenVMS Systems
