A comparison of several statistics—such as database time, average active sessions, and user calls—between the workload capture and the workload replay is also provided. For advanced analysis, Automatic Workload Repository (AWR) reports are available to enable detailed comparison of performance statistics between the workload capture and the workload replay. The information available in these reports is very detailed, and some differences between the workload capture and replay can be expected.</p> <p>For application-level validation, you should consider developing a script to assess the overall success of the replay. For example, if 10,000 orders are processed during workload capture, you should validate that a similar number of orders are also processed during replay.</p> <p>After the replay analysis is complete, you can restore the database to its original state at the time of workload capture and repeat workload replay to test other changes to the system once the workload directory object is backed up to another physical location.</p> <div class="helpinfonotealso"> <h2>Related Topics</h2> <p><a href="dbr_analyze.htm#CACBHAEF">Analyzing Replayed Workload</a> for information about how to analyze data and performance divergence using Database Replay reports</p> <p><a href="dbr_intro.htm#BABBDGIB">Introduction to Database Replay</a></p> </div> </div> <!-- class="sect1" --> <!-- Start Footer --> <div class="footer"> <table class="simple oac_no_warn" summary="" cellspacing="0" cellpadding="0" width="100%"> <col width="86%" /> <col width="*" /> <tr> <td align="left"><span class="copyrightlogo">Copyright © 2008, 2009, Oracle and/or its affiliates.
