<h4><a name="trbprocessintro"></a>Process log files</h4>
<p>Application server processes contain two output streams that are accessible
to native code running in the process. These streams are the <strong>stdout</strong> and <strong>stderr</strong> streams.
Platform-specific code, including the Java virtual machine (JVM), may write
data to these process streams.</p>
<p>By default, the <strong>stdout</strong> and <strong>stderr</strong> streams
are redirected to log files at application server startup, which contain text
written to the <strong>stdout</strong> and <strong>stderr</strong> streams
by native modules (for example, *SRVPGM object). The application server does
not have a special process or format of the output that is written to the process
log.</p>
<p>The log files must have the following granted authorities:</p>
<ul>
<li>*Public *Exclude</li>
<li>QEJBSVR *RW</li>
</ul>
<p>If the application server is running under a user profile other than the default
(QEJBSVR) and the user profile does not have QEJBSVR specified as a group profile,
the user profile must have explicit *RW authority to the process log file.</p>
