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.

Open the OAS object or the device you plan
to modify.
- Set the object or device according to

supersedes the Default ADS Repository attribute of the site for that
engine.
