# Global ACRON settings

In the Global Settings area of the Admin Explorer you can enable/disable diagnosis mode, change the background image, and restart the Database Engine and Database Server automatically and have them deleted at specific intervals.

## Diagnosis mode <a href="#diagnosemodus" id="diagnosemodus"></a>

When ACRON diagnosis mode is enabled, the ACRON modules write diagnostic messages to a log file. The scope of the message is determined by the custom-preset level.

### Explanation on user control

You can use the round buttons to activate and deactivate the individual areas (gray = inactive; green = active; red = disabled). Use the square buttons to change all the areas simultaneously. When diagnosis mode is active you can also activate a logger window as an option. It displays diagnostic messages in real time.

Note

As diagnosis mode heavily influences the performance of the application, and the recorded messages can normally only be evaluated by Technical Support, you should only activate it when prompted to do so by Support.

## Miscellaneous <a href="#verschiedenes" id="verschiedenes"></a>

### Background image

Various background images are available for the local user interface. In the "Pictures" folder you can store your own background images in Bitmap format. You can use the arrow button to reset to a custom background image to the default.

### Delete log files

Entry option to specify the archiving period for log files (min = 3 days, max = 1000 days, default = 30 days).

Note

Changes to the 'lifetime' only take effect when the modules concerned are restarted.
