<h3 align=center>XA Introduction</h3>
<p>Berkeley DB can be used as an XA-compliant resource manager. The XA
implementation is known to work with the Tuxedo(tm) transaction
manager.</p>
<p>The XA support is encapsulated in the resource manager switch
db_xa_switch, which defines the following functions:</p>
<blockquote><pre>__db_xa_close Close the resource manager.
__db_xa_commit Commit the specified transaction.
__db_xa_complete Wait for asynchronous operations to
complete.
__db_xa_end Disassociate the application from a
transaction.
__db_xa_forget Forget about a transaction that was heuristically
completed. (Berkeley DB does not support heuristic
completion.)
__db_xa_open Open the resource manager.
__db_xa_prepare Prepare the specified transaction.
__db_xa_recover Return a list of prepared, but not yet
committed transactions.
__db_xa_rollback Abort the specified transaction.
__db_xa_start Associate the application with a
transaction.
</pre></blockquote>
<p>The Berkeley DB resource manager does not support the following optional
XA features:</p>
<p><ul type=disc>
<li>Asynchronous operations
<li>Transaction migration
</ul>
<p>The Tuxedo System is available from <a href="http://www.beasys.com">BEA Systems, Inc.</a></p>
