Before you deploy the routing engine, a Managed Server should be created in WebLogic Server (WLS). The managed server should have at least four gigabytes of memory in the heap. The more memory that is allocated to the heap, the more local partitions can be kept in the cache. Being able to keep more partitions in the cache is the single best way to improve the performance of the routing engine.
For the routing engine to be successfully deployed on a managed server, the server must have a data source associated with it. This data source provides a pool of connections to the database schema that contains the road network data and user data.
It is recommended that a WLS Work Manager be created and associated with the managed server. A work manager stores constraints on the number of requests that can run concurrently on the managed server. It also stores a constraint on the number of requests that can be queued before the managed server starts rejecting requests.
