The Event repository resides on the ADS/ADX /OAS within the SQL Server software database. You may view and acknowledge ADS/ADX /OAS alarms and events in the event repository. The newest and highest priority alarm or event that requires acknowledgment appears in the Alarms window. Use the Event Viewer to see all the events in a device repository. When the device repository receives an acknowledgment either from the user interface or through a web service, the original source device of the alarm is notified.

The installation program places the Event repository on the same computer where the ADX software resides. The default directory location is C:\ProgramData\Johnson Controls\MetasysIII\SQLData (pre-Release 8.0) or C:\Program Files\Microsoft SQL Server\MSSQL<version>.MSSQLSERVER\MSSQL\DATA (Release 8.0 or later). For a split ADX, the directory location is on the database server computer on the same drive where the SQL Server software is installed. If you want to change where the databases are loaded (for example, E:\MyDatabases), you need to do so before you install the ADS/ADX/OAS software. For details, refer to the Metasys Server Installation and Upgrade Guide (LIT-12012162) or the Metasys Server Lite Installation and Upgrade Instructions (LIT-12012258) .

The ADS/ADX /OAS performance degrades as the number of event samples coming into the ADS/ADX /OAS Event repository increases. In addition, the frequency of the event samples to be stored in the Event repository increases, depending on the hardware resources used for the ADS/ADX /OAS computer.
