<h1 class="topictitle1">Run Java in a batch job</h1>
|
||
|
|
<div><p>Java™ programs run in a batch job by using the Submit
|
||
|
|
Job (SBMJOB) command. In this mode, the Java Qshell Command Entry display is not
|
||
|
|
available to handle the System.in, System.out, nor System.err streams.</p>
|
||
|
|
<div class="section"><p>You may redirect these streams to other files. Default handling
|
||
|
|
sends the System.out and System.err streams to a spooled file. The batch job,
|
||
|
|
which results in an input and output exception for read requests from System.in,
|
||
|
|
owns the spooled file. You can redirect System.in, System.out, and System.err
|
||
|
|
within your Java program. You can also use the os400.stdin, os400.stdout,
|
||
|
|
and os400.stderr system properties to redirect System.in, System.out, and
|
||
|
|
System.err.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> SBMJOB sets the current working directory (CWD) to the
|
||
|
|
HOME directory that is specified in the user profile.</div>
|
||
|
|
<p><strong>Example:</strong> Running Java in
|
||
|
|
a Batch Job</p>
|
||
|
|
<p><samp class="codeph">SBMJOB CMD(JAVA Hello OPTION(*VERBOSE)) CPYENVVAR(*YES)</samp></p>
|
||
|
|
<p>Running
|
||
|
|
the JAVA command in the previous example spawns a second job. Therefore, the
|
||
|
|
subsystem that the batch job runs in must be capable of running more than
|
||
|
|
one job.</p>
|
||
|
|
<p>You can verify that your batch job is capable of running more
|
||
|
|
than one job by following these steps:</p>
|
||
|
|
</div>
|
||
|
|
<ol><li><span>On the CL command line, enter <samp class="codeph">DSPSBSD(MYSBSD)</samp>,
|
||
|
|
where <samp class="codeph">MYSBSD</samp> is the subsystem description of your batch job.</span></li>
|
||
|
|
<li><span>Choose option 6, Job queue entries.</span></li>
|
||
|
|
<li><span>Look at the Max Active field for your job queue.</span></li>
