<h1>Description</h1>
|
|
<a name="3"><!--meow--></a> <a name="4"><!--meow--></a>
|
|
<p>The db_verify utility verifies the structure of one or more
|
|
files and the databases they contain.
|
|
<p>The options are as follows:
|
|
<p><dl compact>
|
|
<p><dt><b>-h</b><dd>Specify a home directory for the database environment; by
|
|
default, the current working directory is used.
|
|
<p><dt><b>-N</b><dd>Do not acquire shared region locks while running. Other problems such as
|
|
potentially fatal errors in Berkeley DB will be ignored as well. This option
|
|
is intended only for debugging errors and should not be used under any
|
|
other circumstances.
|
|
<p><dt><b>-q</b><dd>Suppress the printing of any error descriptions, simply exit success or
|
|
failure.
|
|
<p><dt><b>-V</b><dd>Write the version number to the standard output and exit.
|
|
</dl>
|
|
<p>If the file being verified contains databases using non-default
|
|
comparison or hashing functions, the db_verify utility may
|
|
not be used for verification, as it will likely always return failure.
|
|
Such files must be verified explicitly, using the <a href="../api_c/db_verify.html">DB->verify</a> function,
|
|
after setting the correct comparison or hashing functions.
|
|
<p>The db_verify utility may be used with a Berkeley DB environment (as described for the
|
|
<b>-h</b> option, the environment variable <b>DB_HOME</b>, or,
|
|
because the utility was run in a directory containing a Berkeley DB
|
|
environment). In order to avoid environment corruption when using a Berkeley DB
|
|
environment, db_verify should always be given the chance to detach from
|
|
the environment and exit gracefully. To cause db_verify to release all
|
|
environment resources and exit cleanly, send it an interrupt signal
|
|
(SIGINT).
|
|
<p>The db_verify utility exits 0 on success, and >0 if an error occurs.
|
|
<h1>Environment Variables</h1>
|
|
<p><dl compact>
|
|
<p><dt>DB_HOME<dd>If the <b>-h</b> option is not specified and the environment variable
|
|
DB_HOME is set, it is used as the path of the database home, as described
|
|
in <a href="../api_c/env_open.html">DBENV->open</a>.
|
|
</dl>
