are written as plain text files.
About this task
The SystemOut.log and SystemErr.log JVM
logs are located in the job logs of the application server.

Use either of two techniques to view the JVM
logs for an application server:
- Use the administrative console, which also supports viewing the
JVM logs from a remote machine.
- Use a text editor on the machine where the logs are stored.
Note: This topic references one or more of the application
server log files. As a recommended alternative, you can configure
the server to use the High Performance Extensible Logging (HPEL) log
and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files on distributed and IBM® i systems. You can also use
HPEL in conjunction with your native z/OS® logging facilities. If you are using HPEL, you can access
all of your log and trace information using the LogViewer command-line
tool from your server profile bin directory. See the information
about using HPEL to troubleshoot applications for more information
on using HPEL.
