Install a consolidated database (CDB) so that it is independent of any Unwired Server instance in the cluster.
To improve performance, you may want to install a dedicated CDB in a cluster of Unwired Servers so that it is independent of any Unwired Server within that cluster. Typically, as client load increases, the CDB becomes a bottleneck. If a single Unwired Server becomes a bottleneck, you can always add more servers to your cluster, and the load is balanced between all servers. However, you cannot add more CDBs—one CDB handles the entire load for database-related work. A dedicated CDB improves performance because it does not compete with other Unwired Server components for CPU and I/O resources.
