# Event Archiving (Database Administrator)

VistaLINK™ PRO incorporates an automatic Database Administration feature. It is possible to direct the VistaLINK™ PRO Server to archive any alarms older than a specified duration to an external file. The VistaLINK™ PRO Server achieves this by periodically querying the alarm database for any alarms older than the specified duration. If alarms are found the server runs the Save alarm log feature storing the alarms to an external report file. The Database Administrator can also be run manually at any time. A proper database administration cycle will keep the active alarm database running at best performance. The archive duration should be selected according to the amount of hardware being monitored and how often fault alarms are reported to the VistaLink PRO Server.

#### To Enable or Disable the Database Administrator

1. Select Tools -> Configure Log in the VLPRO Server application or select Tools -> Server Properties in the VLPRO Client application. Either of these two methods will open the Configure Log dialog box .
2. Select the Database Administrator tab and check or un-check the Enable Database Administrator option to enable or disable this feature.

2. Select the Database Administrator tab and change the Archive events that are older than ___ day(s) duration.

Clicking the Run Database Administrator button found in the Configure Log / Database Administrator dialog will immediately run the Database Administrator feature, bypassing its regular schedule thus immediately archiving events according to the Archive events that are older than duration.
