All sessions that successfully connect to Unity are mapped to a routing rule by evaluating the user mapping rules. The user mapping rules are specified by userid, region, account string, and role. The Routing Rule name refers to a specific rule that defines Read and Write request routing properties such as to which system to send the request if a Preferred routing is specified. Profiles refers to a specific error profile that defines whether to exit or failover when a specific error occurs.
| Priority | User ID | Region | Account String | Role | Profile | Routing Rule |
|---|---|---|---|---|---|---|
| 1 | Susan | RegionA | * | * | * | RoutingA |
| 2 | John | * | * | DBA | * | RoutingA |
| 3 | * | * | * | DBA | * | RoutingB |
| 4 | * | * | CRM | * | * | RoutingC |
| 5 | * | * | * | * | * | DefaultRouting |
The first rule with Priority 1 says that if Susan logs on from RegionA, Unity performs session routing based on the rules defined in RoutingA. The wildcard in Profile means that all error profiles are used. If John logs on with an assigned DBA role, then Unity performs session routing also using the RoutingA rule. Otherwise, any user who logs on with the DBA role initiates a session that uses RoutingB.
