Use this information as the best way to configure system controls.
- You have the option of using a z/OS system logger log stream as the WebSphere
Application Server for z/OS error log. The WebSphere variable
ras_log_logstreamName
identifies which log stream you want to use for the error log; it has no default
setting. If you do not use a log stream, however, messages that usually appear
in the error log are directed to server's job log.
- You have the option of directing trace output to SYSPRINT or buffers.
The WebSphere variable
ras_trace_outputLocation
controls the
location of trace output; its default values are SYSPRINT for client applications,
and buffers to all other processes. Although you can change the default for
other processes from buffers to SYSPRINT, performance is better when you use
buffers.
- You can use the Resource Measurement Facility (RMF) to view status information
that might indicate potential problems. WebSphere Application Server for z/OS
uses Workload Manager (WLM) services to report transaction begin-to-end response
times and execution delay times, which might indicate that changes are required
for timeout values or tuning controls.
