<h3><pre>

public void log_flush(DbLsn lsn)
throws DbException;

<h1>Description</h1>
<p>The DbEnv.log_flush method guarantees that all log records whose
<a href="../api_java/lsn_class.html">DbLsn</a> values
are less than or equal to the <b>lsn</b> argument have been
written to disk. If <b>lsn</b> is null, all records in the
log are flushed.
<p>The DbEnv.log_flush method throws an exception that encapsulates a non-zero error value on
failure.
<h1>Errors</h1>
<p>The DbEnv.log_flush method may fail and throw an exception encapsulating a non-zero error for the following conditions:
<p><dl compact>
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
</dl>
<p>The DbEnv.log_flush method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the DbEnv.log_flush method may fail and throw
a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>, in which case all subsequent Berkeley DB calls
will fail in the same way.
