The Audit Repository resides on the OAS within the SQL Server software database. The installation program places the Audit repository on the same computer where the OAS software resides.

The default directory location is C:\Program Files\Microsoft SQL Server\MSSQL<version>.MSSQLSERVER\MSSQL\DATA. If you want to change where the databases are loaded, you need to do so before you install OAS. For details, refer to the Open Application Server (OAS) Installation Instructions (LIT-12013222).

The OAS performance degrades as the number of audit samples coming in to the OAS Audit repository increases. In addition, the frequency of the audit samples to be stored in the Audit repository increases, depending on the hardware resources used for the OAS computer. You can optimize the required storage size of the OAS Audit repository by specifying the Audit level (1 through 4) for the audit messages that need to be reported and archived. In addition, you can optimize the network communication performance for transferring audit messages from engines to the OAS Event repository by optimizing the Audit repository size in the device object of each engine. Audit Level 1 provides the minimum information. Audit Level 4 provides the most information. Audit Level 2 is the default setting.

Refer to the Audit Trail topic in the Metasys SMP Help (LIT-1201793) for more information.
