Java tracing is enabled through a set of parameters configured in the Session Configuration Manager. In all Java display and
printer sessions, tracing is controlled from the
Custom Options page. Tracing in these emulations is at two levels.
- Host Interface Tracing - captures Telnet data that flows between the emulator and the host.
- Session Tracing - captures the emulator specific data stream data.
The following parameters must be entered with a value of either
True or
False in the
Value column:
- EnableHostInterfaceTracing and
EnableSessionTracing determine if these levels are captured.
- HostInterfaceTraceFile and
SessionTraceFile specify the path where the trace files are written and the name assigned to them. If they are left blank, trace data is written
to the Java console (when enabled).
- EnableTraceControlButtons, when set to
True, adds
Record,
Stop, and
Pause buttons to the emulator's toolbar.
- LogMaskHidden, when set to
True, replaces sensitive data in hidden fields with spaces.
When tracing is enabled, but
EnableTraceControlButtons is not set to
True, tracing is always on, and begins as soon as the emulator initiates its connection.
Notes:
- The Java UNIX display does not have a
Customs Options page. Use the
Trace Options page to set all trace parameters.
- For Java AS/400 File Transfer, tracing is set from the
General Options page. Clicking
Enable Trace results in a new trace control button on the emulator’s toolbar.
