<h1 class="topictitle1">Trigger buffer sections</h1>
|
|
<div><p>The trigger buffer has two logical sections: a static section and
|
|
a variable section.</p>
|
|
<div class="p">The static section occupies (in decimal) offset 0 through 95. It contains
|
|
the following items: <ul><li>A trigger template that contains the physical file name, member name,
|
|
trigger event, trigger time, commit lock level, and CCSID of the current record
|
|
and relative record number.</li>
|
|
<li>Offsets and lengths of the record areas and null byte maps. </li>
|
|
</ul>
|
|
</div>
|
|
<p>The variable section contains areas for old record, old null byte map,
|
|
new record, and new null byte map.</p>
|
|
<p>The following table provides a summary of the fields in the trigger buffer.</p>
