In the Preferences section of the information/working area, the following preferences can be modified:

Automatic Restart

Option	Desciption
Tracing and Mockups Enabled	Switching tracing and mockups on / off. All xUML services are compiled with tracing and mockups enabled. This option allows you to turn off the tracing, so that no trace information is returned by the Bridge when a service is called. Noteinfo icon false To change this preference, you have to stop the service - it cannot be changed on a running service. Runtime 2017.8 If you change the flag during runtime, you will get an error "Failed to update the running xUML service". In the service log you will see the following: [2017-10-13 17:14:11 +0200][0000000000][Error][Internal][BELM][47][Fail to handle the change "AddOns/SOAP/Service/base.tab"] Using an older Runtime, you cannot change this preferences on the fly either, but you will not get an error.
Dump Context on Error	Switching error dump on / off. Each time an xUML service throws an exception, actual call stack and data is logged in a trace file. This trace information can be viewed with the E2E Analyzer (function Import Trace from File) or with the E2E Interactive Debugger (function Load Dump File).
Bridge Server Log Level	Related to the xUML service standard log.The Bridge process running the selected xUML service logs activities like starting and stopping xUML services, loading add-ons, etc. according to the log levels listed in a table on Log Levels of an xUML Service. Users, who have MODELER access rights, may only change the log level, if they themselves or a member of the same group deployed the xUML service. The logged information is described in detail on xUML Service Standard Log.
Transaction Log Level	Related to the xUML service transaction log.The Bridge process running the selected xUML service logs data usable for performance measurements or statistical evaluations. The transaction log levels are described on Transaction Log Levels of an xUML Service. Users, who have MODELER access rights, may only change the log level, if they themselves or a member of the same group deployed the xUML service. The logged information is described in detail on xUML Service Transaction Log.
Transaction Log Rotation Interval	Related to the xUML service transaction log. The transaction log rotation interval configures the segmentation of the transaction log: one logfile per day or one logfile per hour (default is daily). Users, who have MODELER access rights, may only change the log level, if they themselves or a member of the same group deployed the xUML service.
Automatic Startup	Multiexcerpt-include MultiExcerptName automatic_startup PageWithExcerpt INTERNAL:_bridge_excerpts
Select this option, if you want the service to startup automatically, whenever the E2E Bridge is started.  Only users who are member of a group, to which the role ADMIN has been assigned, are allowed to change this option. Note icon false This option can be globally disabled by the Disable Automatic Service Startup option on the node instance preferences.
Multiexcerpt-include MultiExcerptName automatic_restart Whenever the service crashes, it will restart immediately. Nevertheless, in the navigation the icon Image Removed next to the xUML service name will indicate the abnormal termination. PageWithExcerpt INTERNAL:_bridge_excerpts
Owner	Multiexcerpt-include MultiExcerptName owner The group id of the user who has deployed the service. Only users who are member of a group, to which the role ADMIN has been assigned, are allowed to modify the owner of the service. PageWithExcerpt INTERNAL:_bridge_excerpts
Timer Enabled	Switching timers on / off.
Scheduler Enabled	Switching schedulers on / off.

Users with USER access rights may not change any of these preferences.

Click Apply to save your modifications. All future incidents will be handled according to the new settings.

Updating or reinstalling the Bridge (by keeping the deployed xUML service) will reset the automatic startup and owner preferences. The automatic startup option will be deselected, and the owner will be reset to user id admin.
