<h5><a name="trbjvminterp"></a><strong>Interpret the contents for the Java virtual

machine log files</strong></h5>
|

|
|
<p>The Java virtual machine (JVM) writes data to the logs using two different
|
||
|
|
formats, Basic and Advanced format. The Basic and Advanced formats use the
|
||
|
|
same fields and formatting techniques with the exception that Advanced format
|
||
|
|
adds information about events when possible.</p>
|
