Switching the Coverage Analyzer On and Off: The Main Switch

Procedure

Activate or deactivate the Coverage Analyzer with the buttons in the Switch Coverage Analyzer On/Off frame.

Note

The start screen of transaction SCOV shows you the activation status of the Coverage Analyzer in summary.

Activation: To activate the Coverage Analyzer and have it collect code coverage statistics, choose the On button in the Switch Coverage Analyzer On/Off frame.

If the Coverage Analyzer displays the message Maintain background server for data collection in settings (message ID COV, message number 254), then you must first choose Settings in the Administration function list.

In the Background Job for Triggering Data Collection frame in Settings, specify the background server that the Coverage Analyzer should use for data collection. This can be any instance in your system that offers background processing. You may need to maximize the SAPGUI screen to display the Data Collection frame.

You can identify such a server in transaction SM51; choose a server that offers the Message Type Batch. Enter the Batch Server name in the form shown in SM51: host_SID_systemnumber. For Period (Minutes) you can enter 45. Once you have saved the settings, you can return to the On/Off, Status function to switch on the Coverage Analyzer.

Go on to activate the Coverage Analyzer in at least one of the application servers on the system.

For the Coverage Analyzer to work, both the 'main switch' and at least one application server must be 'on'.

Figure 1: To see code coverage data, both the main switch and at least one application server must be activated and green.

Please also note the following:

The Coverage Analyzer schedules the data collection job RSCVR_TRIGGER_COLLECT to run on the application server at which you are logged on. By default, the job runs every 45 minutes. The job should not produce significant batch workload, so any application server that offers the background service will do.

You can display code coverage results in the Detail Display. Data should be visible there as soon as the initialization is finished and at least one instance of the RSCVR_TRIGGER_COLLECT job has finished.

To see code coverage statistics in the Global Display as well, you must also activate history recording. Otherwise, the Global Display will remain empty.

Deactivation: Turning off the Coverage Analyzer deletes all current statistics, including both current counters and cumulative counters. Statistics saved in histories are not affected by a deactivation.
