<div><p>The <em>remote unit of work</em> facility provides for the remote
preparation and processing of SQL statements.</p>
<div class="section"><p>An activation group at computer server A can connect to an application
server at computer server B. Then, within one or more units of work, that
activation group can process any number of static or dynamic SQL statements
that reference objects at B. After ending a unit of work at B, the activation
group can connect to an application server at computer server C, and so on.</p>
</div>
<div class="section"><p>Most SQL statements can be remotely prepared and processed with
the following restrictions:</p>
<ul><li>All objects referenced in a single SQL statement must be managed by the
same application server.</li>
<li>All of the SQL statements in a unit of work must be run by
the same application server.</li>
