<p>
Application components running at various sites within a
replication group can now use the Replication Manager's existing
TCP/IP communications infrastructure to send and process messages
among themselves, using the <code class="literal">DB_CHANNEL</code> handle.
<a href="../api_reference/C/repmgr_channel.html" class="olink">DB_ENV->repmgr_channel()</a> is used to create the
<code class="literal">DB_CHANNEL</code> handle. <a href="../api_reference/C/dbchannel_send_msg.html" class="olink">DB_CHANNEL->send_msg()</a> and
<a href="../api_reference/C/dbchannel_send_request.html" class="olink">DB_CHANNEL->send_request()</a> are used to send sychronous and
asychronous messages that are handled by the function set by
<a href="../api_reference/C/repmgr_msg_dispatch.html" class="olink">DB_ENV->repmgr_msg_dispatch()</a>. <a href="../api_reference/C/dbchannel_set_timeout.html" class="olink">DB_CHANNEL->set_timeout()</a> is used to
configure channel time out, and <a href="../api_reference/C/dbchannel_close.html" class="olink">DB_CHANNEL->close()</a> closes the
channel and frees resources held by it.
