Berkeley DB can be used as an XA-compliant resource manager.
|
||
The XA implementation is known to work with the Tuxedo
|
||
transaction manager.
|
||
</p>
|
||
<p>
|
||
The XA support is encapsulated in the resource manager
|
||
switch db_xa_switch, which defines the following
|
||
functions:
|
||
</p>
|
||
<div class="itemizedlist">
|
||
<ul type="disc">
|
||
<li><span class="emphasis"><em>__db_xa_close.</em></span>
|
||
Close the resource manager.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_commit. </em></span>
|
||
Commit the specified transaction.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_complete.</em></span>
|
||
Wait for asynchronous operations to complete.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_end. </em></span>
|
||
Disassociate the application from a
|
||
transaction.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_forget.</em></span>
|
||
Forget about a transaction that was heuristically
|
||
completed. (Berkeley DB does not support heuristic
|
||
completion.)
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_open.</em></span> Open
|
||
the resource manager.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_prepare.</em></span>
|
||
Prepare the specified transaction.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_recover.</em></span>
|
||
Return a list of prepared, but not yet committed
|
||
transactions.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_rollback.</em></span>
|
||
Abort the specified transaction.
|
||
</li>
|
||
<li><span class="emphasis"><em>__db_xa_start.</em></span>
|
||
Associate the application with a transaction.
|
||
</li>
|
||
</ul>
|
||
</div>
|
||
<p>
|
||
The Berkeley DB resource manager does not support the
|
||
following optional XA features:

</p>
|
||
<div class="itemizedlist">
|
||
<ul type="disc">
|
||
<li>
|

Asynchronous operations

<li>
|

Transaction migration
|

</li>
