<b>Description: DbEnv::rep_set_limit</b>
<p>The DbEnv::rep_set_limit method sets 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 href="../api_cxx/rep_message.html">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 DbEnv::rep_set_limit 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="../ref/env/db_config.html#DB_CONFIG">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 parameters.
For example, "rep_set_limit 0 1048576" sets a 1 megabyte limit.
Because the <a href="../ref/env/db_config.html#DB_CONFIG">DB_CONFIG</a> file is read when the database environment
is opened, it will silently overrule configuration done before that
time.</p>
<p>The DbEnv::rep_set_limit method configures a database environment, not only operations
performed using the specified <a href="../api_cxx/env_class.html">DbEnv</a> handle.</p>
<p>The DbEnv::rep_set_limit method may be called at any time during the life of the
application.</p>
<p>The DbEnv::rep_set_limit 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.
</p>
<b>Parameters</b> <br>
<b>bytes</b><ul compact><li>The <b>gbytes</b> and <b>bytes</b> parameters specify the maximum
number of bytes that will be sent in a single call to <a href="../api_cxx/rep_message.html">DbEnv::rep_process_message</a> method.</ul>
<b>gbytes</b><ul compact><li>The <b>gbytes</b> and <b>bytes</b> parameters specify the maximum
number of bytes that will be sent in a single call to <a href="../api_cxx/rep_message.html">DbEnv::rep_process_message</a> method.</ul>
<br>

<b>Description: rep_get_limit</b>
<p>The DbEnv::rep_get_limit method may be called at any time during the life of the
application.</p>
<p>The DbEnv::rep_get_limit 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.
</p>
<b>Parameters</b> <br>
<b>bytesp</b><ul compact><li>The <b>bytesp</b> parameter references memory into which
the additional bytes of memory in the current transmit limit is copied.</ul>
<b>gbytesp</b><ul compact><li>The <b>gbytesp</b> parameter references memory into which
the gigabytes of memory in the in the current transmit limit is copied.</ul>
