<p>
The <code class="methodname">DbSite::set_config()</code> method configures
a Replication Manager site.
</p>
<p>
The <code class="methodname">DbSite::set_config()</code> <span>
<span>
method either returns a non-zero error value or throws an
exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
</span>
</span>
</p>
<p>
The Replication Manager site may also be configured using the
environment's DB_CONFIG file. The syntax of the entry in that file
is described in
<a class="xref" href="repmgr_site_parameter.html" title="repmgr_site">repmgr_site</a>.

This parameter must be set to one of the following

<ul type="disc">
<li>
<p><a id="DB_BOOTSTRAP_HELPER"></a>
<code class="literal">DB_BOOTSTRAP_HELPER</code>
</p>
<p>
Specifies that a remote site may be used as a
"helper" when the local site is first joining the
replication group. Once the local site has been
established as a member of the group, this
setting is ignored.
</p>
</li>
<li>
<p><a id="DB_GROUP_CREATOR"></a>
<code class="literal">DB_GROUP_CREATOR</code>
</p>
<p>
Specifies that this site should create the
initial membership database contents, defining a
"group" of just the one site, rather than trying to
join an existing group when it starts for the first
time.
</p>
<p>
This setting can only be used on the local site and
is ignored when configured for a remote site.
</p>
</li>
<li>
<p><a id="DB_LEGACY"></a>
<code class="literal">DB_LEGACY</code>
</p>
<p>
Specifies that the site is already part of an
existing group. This setting causes the site to be
upgraded from a previous version of BDB. All sites
in the legacy group must specify this setting for
themselves (the local site) and for all other sites
currently existing in the group. Once the upgrade
has been completed, this setting is no longer
required.
</p>
</li>
<li>
<p><a id="DB_LOCAL_SITE"></a>
<code class="literal">DB_LOCAL_SITE</code>
</p>
<p>
Specifies that this site is the local site within
the replication group. The application must
identify exactly one site as the local site in this
way, before calling the
<a class="xref" href="repmgrstart.html" title="DbEnv::repmgr_start()">DbEnv::repmgr_start()</a>
method.
</p>
</li>
<li>
<p><a id="DB_REPMGR_PEER"></a>
<code class="literal">DB_REPMGR_PEER</code>
</p>
<p>
Specifies that the site may be used as a target for
"client-to-client" synchronization messages. This
setting is ignored if it is specified for the local
site.
