Using deployment templates, you can define a collection of materialized view definitions at a master site and use parameters in the definitions so that the materialized views can be customized for individual users or types of users.</p> <p>For example, you might create one template for the sales force and another template for field service representatives. In this case, a parameter value might be the sales territory or the customer support level. When a user instantiates a template, the appropriate materialized views are created and populated at the remote site.</p> <p>Before you create a deployment template, complete the following tasks:</p> <ul> <li> <p>Read <a href="javascript:open('http://www.oracle.com/pls/db112/lookup?id=REPLN003','newWindow').focus()">Chapter 3, "Materialized View Concepts and Architecture"</a> and <a href="javascript:open('http://www.oracle.com/pls/db112/lookup?id=REPLN004','newWindow').focus()">Chapter 4, "Deployment Templates Concepts and Architecture"</a> in <a href="javascript:open('http://www.oracle.com/pls/db112/lookup?id=REPLN','newWindow').focus()"><span class="italic">Oracle Database Advanced Replication</span></a> for more information.</p> <p>Understanding how materialized views are created and how they work will better prepare you to build deployment templates.</p> </li> <li> <p>Connect to the master site where you want to create the deployment template.</p> </li> <li> <p>Create a materialized view log for each master table that will support materialized views. A materialized view log is required for materialized views to perform fast refreshes with the master table.</p> <p>See <a href="materialized002.htm#BEIHCICE">Creating Materialized View Logs</a> for instructions.</p> </li> <li> <p>If conflicts are possible at the master site because of activity at the materialized view sites you are creating, then configure conflict resolution for the master tables of the materialized views before you instantiate the deployment template.</p> <p>See <a href="configure001.htm#CACJABIJ">About Conflict Resolution Methods</a> for more information about configuring conflict resolution.</p> </li> </ul> <div class="helpinfonote"> <p><span class="bold">Note: </span>If you plan to define conflict resolution methods or use column subsetting for materialized views that you add to the deployment template, then you must first quiesce the master group containing the objects. Also, column-subsetted materialized views are available only when using the Replication Deployment Template Wizard.</p> </div> <div class="helpinfonotealso"> <h2>Related Topics</h2> <p><a href="deployment002.htm#BABIDIHJ">Flowchart for Using Deployment Templates</a></p> <p><a href="basic_concepts018.htm#CHDEJGFA">Deployment Templates</a></p> <p><a href="deployment003.htm#BABBDEHC">Creating a Deployment Template</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 © 2005, 2009, Oracle and/or its affiliates.
