Changing the ranking of a service provider

The controller creates an entry in the AR System Service Failover Ranking form under the following circumstances:

• When an entry is created in the AR System Service Whiteboard form
• When a waiting or active provider is examined as a possible highest rank

If no other rankings exist for the service, the entry receives a ranking of 1.  If other rankings exist, the entry receives a null ranking (that is, an unset ranking), which is treated as the lowest ranking (MAXINT (2³² - 1)). This ranking assumes that existing providers are already working, and a failover is not triggered when you introduce a new provider.

Rank is in ascending numerical order. Service providers with the numerically lower rank are chosen before ranks of greater value (negative-valued rank takes a higher precedence over positive-valued rank). If two providers of the same service have the same rank, then the service failover controller chooses one.

To change the ranking of a service provider

1. In a browser, open the AR System Service Failover Ranking form in search mode:
   http://midTierServer:portNumber/arsys/forms/ ARSystemServer/AR+System+Service Failover+Ranking/
2. Perform a search to see the entries in the form, and select the required entry.

3. Change the value in the Rank field.The valid value for this field is any integer.

   A negative-valued rank takes precedence over a positive-valued rank.

4. Save the form.
