Capturing a workload involves recording all requests made by external clients to Oracle Database.</p> <p>When workload capture is enabled, all external client requests directed to Oracle Database are tracked and stored in binary files—called <a id="sthref11" name="sthref11"></a>capture files—on the file system. You can specify the location where the capture files will be stored. Once workload capture begins, all external database calls are written to the capture files. The capture files contain all relevant information about the client request, such as SQL text, bind values, and transaction information. Background activities and database scheduler jobs are not captured. These capture files are platform independent and can be transported to another system.</p> <div class="helpinfonotealso"> <h2>Related Topics</h2> <p><a href="dbr_capture.htm#CACICAAC">Capturing a Database Workload</a> for information about how to capture a workload on the production system</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.
