A repository provides long-term storage for historical data. To generate and retain historical data in the system repository, you require the Historical Data feature license. If unlicensed, the site user only has access to the most recent seven days worth of historical data, plus any additional engine buffer data outside of that seven days. Any data that exceeds the engine buffer limits becomes permanently unavailable to the system.

The Site Director provides the individual repositories for trend data, event messages, audit messages, annotations, reporting, spaces authorization, potential problem areas, fault detection, and fault triage data. The individual repositories reside in the SQL Server database.

Three new SQL databases: MetasysValue, MetasysFault, and MetasysFaultTriage were introduced at Metasys Release 11.0. To activate the databases, license the associated Metasys features. These include Potential Problem Areas, Fault Detection, and Fault Triage. The MetasysValue and MetasysFault databases self-maintain and store a rolling seven days’ worth of data. These databases are not monitored or managed by Metasys Database Manager.

The following table lists the OAS repositories, the corresponding Metasys SMP Help (LIT-1201793) or Metasys UI Help (LIT-12011953) topic, and the corresponding file name. The next sections describe the repositories in more detail and suggest ways to optimize the repositories.
