Although closing a database also closes any open cursors, it is
|
|
recommended that applications explicitly close all their Cursor
|
|
objects before closing the database. The reason why is that when the
|
|
cursor is explicitly closed, the memory allocated for it is
|
|
reclaimed; however, this does not happen if you close a database
|
|
while cursors are still opened.
|
|
</p>
|
|
<p>
|
|
The same rule, for the same reasons, holds true for
|
|
<a href="T_BerkeleyDB_Transaction.htm">Transaction</a> objects. Simply make sure you resolve
|
|
all your transaction objects before closing your database handle.
|
|
</p>
|
|
<p>
|
|
Because key/data pairs are cached in-memory, applications should
|
|
make a point to always either close database handles or sync their
|
|
data to disk (using <a href="M_BerkeleyDB_BaseDatabase_Sync.htm">Sync<span class="languageSpecificText"><span class="cs">()</span><span class="cpp">()</span><span class="nu">()</span></span></a> before exiting, to
|
|
ensure that any data cached in main memory is reflected in the
|
|
underlying file system.
|
|
</p>
|
|
<p>
|
|
When called on a secondary index's primary database, the primary
|
|
should be closed only after all secondary indices referencing
|
|
it have been closed.
|
|
</p>
|
|
<p>
|
|
When multiple threads use the object concurrently, only a
|
|
single thread may call the Close method.
|
|
</p>
|
|
<p>
|
|
The object may not be accessed again after Close is called,
|
|
regardless of its outcome.
|
|
</p>
