hierarchy. The following generic DDL statement is used to create

it:</p><pre class="programlisting">CREATE TABLE BATCH_JOB_INSTANCE (

VERSION BIGINT,

<code class="classname">JobInstance</code>.</p></li><li class="listitem" epub:type="list-item"><p>VERSION: See above section.</p></li><li class="listitem" epub:type="list-item"><p>JOB_NAME: Name of the job obtained from the
