Berkeley DB will perform an internal initialization from the master to the client automatically and will run recovery on the client to bring it up to date with the master.</p> <p>For Base API applications, connecting to a new site in the replication group happens whenever the <a href="../api_reference/C/repmessage.html" class="olink">DB_ENV->rep_process_message()</a> method returns <a href="../api_reference/C/repmessage.html#repmsg_DB_REP_NEWSITE" class="olink">DB_REP_NEWSITE</a>. The application should assign the new site a local environment ID number, and all future messages from the site passed to <a href="../api_reference/C/repmessage.html" class="olink">DB_ENV->rep_process_message()</a> should include that environment ID number. It is possible, of course, for the application to be aware of a new site before the return of <a href="../api_reference/C/repmessage.html" class="olink">DB_ENV->rep_process_message()</a> (for example, applications using connection-oriented protocols are likely to detect new sites immediately, while applications using broadcast protocols may not).</p> <p>Regardless, in applications supporting the dynamic addition of database environments to replication groups, environments joining an existing replication group may need to provide contact information. (For example, in an application using TCP/IP sockets, a DNS name or IP address might be a reasonable value to provide.) This can be done using the <span class="bold"><strong>cdata</strong></span> parameter to the <a href="../api_reference/C/repstart.html" class="olink">DB_ENV->rep_start()</a> method. The information referenced by <span class="bold"><strong>cdata</strong></span> is wrapped in the initial contact message sent by the new environment, and is provided to the existing members of the group using the <span class="bold"><strong>rec</strong></span> parameter returned by <a href="../api_reference/C/repmessage.html" class="olink">DB_ENV->rep_process_message()</a>. If no additional information was provided for Berkeley DB to forward to the existing members of the group, the <span class="bold"><strong>data</strong></span> field of the <span class="bold"><strong>rec</strong></span> parameter passed to the <a href="../api_reference/C/repmessage.html" class="olink">DB_ENV->rep_process_message()</a> method will be NULL after <a href="../api_reference/C/repmessage.html" class="olink">DB_ENV->rep_process_message()</a> returns <a href="../api_reference/C/repmessage.html#repmsg_DB_REP_NEWSITE" class="olink">DB_REP_NEWSITE</a>.</p> <p>Replication Manager automatically distributes contact information using the mechanisms previously described.</p> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="rep_comm.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="rep.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="group_membership.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Building the communications infrastructure </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Managing Replication Manager Group Membership</td> </tr> </table> </div> </body> </html>
