Catastrophic recovery is used when normal recovery is
unable to repair a corrupted database.
A detailed description of the recovery utility is described at
<a href="../api_reference/C/db_recover.html" class="olink">db_recover</a>
. This
section describes how to use the utility with a SQL database.
</p>
<p>
The first step in running recovery is to add a <a href="../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a>
file
to the journal directory. In the file, add the following line:
</p>
<code class="code">
add_data_dir ..
</code>
<p>
Then execute the following command in the journal directory
<span class="command"><strong>db_recover -c</strong></span>.
