To optimize your application's performance, remember to utilize the following features:</p> <ul> <li> <p>Use bind variables within your application whenever possible. You can reference session state values using bind variable syntax in SQL queries and application logic such as PL/SQL executed from processes and validations. Accessing session state using bind variables is the most efficient way to reference session state.</p> </li> <li> <p>Include a <code>#TIMING#</code> substitution string in the region footer so that you can view the timing of each region.</p> </li> </ul> <div align="center"> <div class="inftblnotealso"><br /> <table class="NoteAlso oac_no_warn" summary="" cellpadding="3" cellspacing="0"> <tbody> <tr> <td align="left"> <p class="notep1">See Also:</p> <ul> <li> <p><a href="concept_bind_var.htm#BEIEGCCC">"About Bind Variable Syntax"</a></p> </li> <li> <p><a href="concept_sub.htm#BEIFGFJF">"Understanding Substitution Strings"</a></p> </li> </ul> </td> </tr> </tbody> </table> <br /></div> <!-- class="inftblnotealso" --></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 © 2003, 2009, Oracle and/or its affiliates.
