The <code class="methodname">DbTxn::abort()</code> method causes an abnormal termination of the
|
|||
|
|
transaction. The log is played backward, and any necessary undo
|
|||
|
|
operations are done through the <span class="bold"><strong>tx_recover</strong></span>
|
|||
|
|
function specified to <a class="xref" href="envset_app_dispatch.html" title="DbEnv::set_app_dispatch()">DbEnv::set_app_dispatch()</a>.
|
|||
|
|
Before <code class="methodname">DbTxn::abort()</code> returns, any locks held by the transaction
|
|||
|
|
will have been released.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
In the case of nested transactions, aborting a parent transaction
|
|||
|
|
causes all children (unresolved or not) of the parent transaction to
|
|||
|
|
be aborted.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
All cursors opened within the transaction must be closed before the
|
|||
|
|
transaction is aborted.
|
|||
|
|
If they are not closed, they will be closed by
|
|||
|
|
this function. If a close operation fails, the rest
|
|||
|
|
of the cursors are closed, and the database environment is set to the panic state.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
After <code class="methodname">DbTxn::abort()</code> has been called, regardless of its return, the
|
|||
|
|
<a class="link" href="txn.html" title="Chapter 13. The DbTxn Handle">DbTxn</a> handle may not be
|
|||
|
|
accessed again.

|

exception that encapsulates a non-zero error value on

failure, and returns 0 on success.
