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.

                  - 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.
