<p>
Transactions may only span threads if they do so serially;
each transaction must be active in only a single thread of control
at a time. This restriction holds for parents of nested transactions
as well; no two children may be concurrently active in more than one
thread of control at any one time.
</p>
<p>
Cursors may not span transactions; each cursor must be
opened and closed within a single transaction.
</p>
<p>
A parent transaction may not issue any Berkeley DB operations
except for <a href="M_BerkeleyDB_DatabaseEnvironment_BeginTransaction.htm">BeginTransaction<span class="languageSpecificText"><span class="cs">()</span><span class="cpp">()</span><span class="nu">()</span></span></a>,

while it has active child transactions (child transactions that
have not yet been committed or aborted).
