<p>
The <code class="methodname">DbEnv::rep_set_limit()</code> method sets
record transmission throttling. This is a byte-count limit on the
amount of data that will be transmitted from a site in response to a
single message processed by the
<a class="xref" href="repmessage.html" title="DbEnv::rep_process_message()">DbEnv::rep_process_message()</a>
method. The limit is not a hard limit, and the record that exceeds
the limit is the last record to be sent.
</p>
<p>
Record transmission throttling is turned on by default with a limit of
10MB.
</p>
<p>
If the values passed to the <code class="methodname">DbEnv::rep_set_limit()</code> method are both
zero, then the transmission limit is turned off.
</p>
<p>
The database environment's replication subsystem may also be configured using the
environment's <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file. The
syntax of the entry in that file is a single line with the string "rep_set_limit", one or
more whitespace characters, and the limit specified in two parts: the
gigabytes and the
bytes values. For example, "rep_set_limit 0 1048576" sets a 1 megabyte limit.. Because
the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is read when
the database environment is opened, it will silently overrule configuration done before
that time.
</p>
<p>
The <code class="methodname">DbEnv::rep_set_limit()</code> method configures a database environment,
not only operations performed using the specified <a class="link" href="env.html" title="Chapter 5. The DbEnv Handle">DbEnv</a>
handle.
</p>
<p>
The <code class="methodname">DbEnv::rep_set_limit()</code> method may be called at any time during
the life of the application.
</p>
<p>
The <code class="methodname">DbEnv::rep_set_limit()</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.
