Important: The OAS Repository attribute in the engine and the OAS Repositories attribute in the server determine where the device sends historical information. The Default OAS Repository attribute in the Site object defines where historical data is stored. By default, these repository attributes are blank. Be sure to enter the address or name of your repository device (typically the Site Director) in these attributes to ensure that you do not lose historical data. For the Site Director itself, leave the OAS Repositories attribute blank if the Site Director also serves as the repository. The Site object's Default OAS Repository attribute defines the location of the OAS repository for all devices on the site that do not have the OAS Repository or OAS Repositories attribute defined on their own. The OAS Repository attribute, once defined on a network engine, supersedes the Default OAS Repositories attribute of the site for that engine.

To generate and retain historical data in the system repository, you require the Historical Data 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.

OAS does not support the configuration of multiple servers on a site, so the OAS is the Site Director by default and provides the individual repositories for trend data, event messages, audit messages, annotations, reporting, and spaces authorization data.
  1. Open the OAS object or the device you plan to modify.
  2. Set the object or device according to (Table 1).
