<p>A transaction manager calls <strong>db2xa_prepare()</strong> to request that
|
|
a resource manager prepare for commitment any work performed on behalf of
|
|
<em>*xid</em>. The resource manager places all resources used in the
|
|
transaction branch in a state that the changes can be made permanently when it
|
|
later receives the <strong>db2xa_commit()</strong> request. All associations
|
|
for <em>*xid</em> must have been ended by calling
|
|
<strong>db2xa_end()</strong> prior to the prepare request.</p>
|
|

about parameters, authorities required, return values, and error conditions,
