Service failover ranking entries
- 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.
