When necessary, Oracle orders the execution of dependent transactions to ensure global database integrity. When you specify parallel propagation with Oracle Enterprise Manager:</p> <ul> <li> <p>Specify <code>1</code> to use parallel propagation with only one parallel process.</p> </li> <li> <p>Specify greater than one for parallel propagation with the number of parallel processes specified.</p> </li> <li> <p>Specify <code>0</code> (zero) for serial propagation.</p> </li> </ul> <p>For most environments, <code>1</code> is the best setting. If set to greater than <code>0</code>, then make sure the initialization parameters <code>PARALLEL_MIN_SERVERS</code> and <code>PARALLEL_MAX_SERVERS</code> are configured correctly.</p> <p><code>PARALLEL_MIN_SERVERS</code> specifies the minimum number of parallel execution processes for the instance. This value is the number of parallel execution processes Oracle creates when the instance is started. If you use parallel propagation, make sure you have at least one process for each stream.</p> <p><code>PARALLEL_MAX_SERVERS</code> specifies the maximum number of parallel execution processes and parallel recovery processes for an instance. As demand increases, Oracle will increase the number of processes from the number created at instance startup up to this value. If you use parallel propagation, make sure the value of this parameter is set high enough to support it.</p> <div class="helpinfonotealso"> <h2>Related Topics</h2> <p><a href="setting_up001.htm#BABHDIJF">Setting Up Master Sites</a></p> <p><a href="setting_up002.htm#BABIHGDG">Setting Up Materialized View Sites</a></p> <p><a href="administer016.htm#BABIIDJJ">Viewing and Editing a Scheduled Link</a></p> <p><a href="javascript:open('http://www.oracle.com/pls/db112/lookup?id=REPLN','newWindow').focus()"><span class="italic">Oracle Database Advanced Replication</span></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.
