Connection pooling

PRPC uses a single user account but may make multiple simultaneous connections to each external database, on demand. Connections are shared among multiple requestors, a technique known as connection pooling.

For example, when started, PRPC makes two connections to the PegaRULES database. If demand grows, it makes more connections (up to an optional limit) to provide good service. Connections once opened remain in a pool to be reused for later database requests, eliminating the costly overhead of signing on to the database.
