This documentation article is a legacy resource describing the functionality of the deprecated OpenAccess Classic only. The contemporary documentation of Telerik OpenAccess ORM is available here.

This category provides information on how your application manages ObjectScopes (OS). Watch out for OS Closed Auto and OS Closed Auto Tx as these indicate that OSs are not being closed. This can cause a database lock contention and reduce throughput. The Local OS Allocated metric is effectively a request counter for web applications that use the "one OS per request" model.
