The <code class="methodname">DB_ENV->set_verbose()</code> method turns specific additional
|
|||
|
|
informational and debugging messages in the Berkeley DB message output
|
|||
|
|
on and off. To see the additional messages, verbose messages must
|
|||
|
|
also be configured for the application. For more information on
|
|||
|
|
verbose messages, see the <a class="xref" href="envset_msgfile.html" title="DB_ENV->set_msgfile()">DB_ENV->set_msgfile()</a>
|
|||
|
|
method.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
The database environment's messages 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 "set_verbose", one or
|
|||
|
|
more whitespace characters, and the method
|
|||
|
|
<span class="bold"><strong>which</strong></span> parameter as a string and
|
|||
|
|
optionally one or more whitespace characters, and the string "on"
|
|||
|
|
or "off". If the optional string is omitted, the default is "on";
|
|||
|
|
for example, "set_verbose DB_VERB_RECOVERY" or "set_verbose
|
|||
|
|
DB_VERB_RECOVERY on". 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">DB_ENV->set_verbose()</code> method configures operations performed
|
|||
|
|
using the specified <a class="link" href="env.html" title="Chapter 5. The DB_ENV Handle">DB_ENV</a> handle, not all
|
|||
|

operations performed on the underlying database environment.
