<h1>Description</h1>
<p>The DbEnv.set_verbose method turns additional informational and
debugging messages in the Berkeley DB message output on and off. If
<b>onoff</b> is set to
true,
the additional messages are output.
<p>The <b>which</b> parameter must be set to one of the following values:
<p><dl compact>
<p><dt><a name="Db.DB_VERB_CHKPOINT">Db.DB_VERB_CHKPOINT</a><dd>Display checkpoint location information when searching the log for
checkpoints.
<p><dt><a name="Db.DB_VERB_DEADLOCK">Db.DB_VERB_DEADLOCK</a><dd>Display additional information when doing deadlock detection.
<p><dt><a name="Db.DB_VERB_RECOVERY">Db.DB_VERB_RECOVERY</a><dd>Display additional information when performing recovery.
<p><dt><a name="Db.DB_VERB_WAITSFOR">Db.DB_VERB_WAITSFOR</a><dd>Display the waits-for table when doing deadlock detection.
</dl>
<p>The DbEnv.set_verbose interface may be used to configure Berkeley DB at any time
during the life of the application.
<p>The DbEnv.set_verbose method throws an exception that encapsulates a non-zero error value on
failure.
<p>The database environment's verbosity may also be set using the environment's
<b>DB_CONFIG</b> file. The syntax of the entry in that file is a
single line with the string "set_verbose", one or more whitespace characters,
and the interface <b>which</b> argument as a string, for example,
"set_verbose DB_VERB_CHKPOINT". Because the <b>DB_CONFIG</b> file is read when the database
environment is opened, it will silently overrule configuration done
before that time.
<h1>Errors</h1>
