<p>Log file formats and the Btree, Recno and Hash Access Method database
|
||
formats changed in the Berkeley DB 3.0 release. (The on-disk Btree/Recno
|
||
format changed from version 6 to version 7. The on-disk Hash format
|
||
changed from version 5 to version 6.) Until the underlying databases
|
||
are upgraded, the <a href="../api_reference/C/dbopen.html" class="olink">DB->open()</a> method will return a <code class="literal">DB_OLD_VERSION</code>
|
||
error.</p>
