The Annotation repository resides on the OAS within the SQL Server software database. The Annotation repository contains all optional annotations entered manually through SMP for items in the All Items tree.

The installation program places the Event 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 annotations in the OAS Annotation repository increases and the frequency of the annotation samples to be stored in the Annotation repository increases, depending on the hardware resources used for the OAS computer. The Annotation repository requires no special optimization because the repository only grows in size as the number of annotations increases.
